Wouldn't a dimmer switch provide variable voltage to motor
Just go to the nearest thrift store and look for an old electric sewing machine and use the pedal from that for a throttle.
@@tstricklin4808you read my mind haha
@@dbomber69better use that sewingmachinemotor too then.
Connecting a (much) bigger motor to that pedal will just make it smoke (and burn).
@@tstricklin4808 No, or not really, a dimmer switch, aka a TRIAC, cuts off the leading portion of the AC waveform, which causes worse and worse jolts to the motor and will eventually just kill the motor. A Variac is what can provide variable voltage, its kind of in the name, Variac, Vari-AC, Variable AC, its a generic trade name for what is called a "variable autotransformer" and they have been used for decades to vary the voltage of AC devices and it also acts as a half-decent isolation transformer by nature. Add in a polarity switch between the Variac and the motor and you can go forward and backward.
Edit: Never mind, this is a synchronous motor rather than a normal AC induction motor, it did come off a lathe after all.
You need a 208V 3HP 3 phase motor with a 240V 1phase input to 208V 3 phase Variable frequency drive, use a potentiometer to control the frequency of the VFD, you'll have full torque, reverse, and can go from 0 to about 5000RPM on a 3600RPM 2 pole motor.
This is the correct answer. Used to do this for motors that we needed to ramp up slowly.
Bingo!
This !!!
Then you'll need a better generator
I bet that exceeds their electrical expertise and budget. But yes, you are right.
A rusted flooded out generator, a pile of parts from the parts bin, a few bells and whistles from Go Power Sports and an "It'll be fine!" attitude... man I love this channel. Hope you guys have a fun holiday!
Pshhhh, you seen these guys do their thing? It'll Be Fine! Just like you said!
fr
Wish my “parts bin” looked anything near what theirs does…
Just wheels alone are a pain in the ass to come across now days
Use a 240 sliding dimmer light switch, can use 2 springs 1 on each side on 1 side, and a throttle cable on the other side. That way you can actually have a working "throttle" lmao
That wouldn't work, you need to vary the frequency to change the speed of an ac motor. Reducing voltage or using a triac dimmer will only cause increased amp draw and component damage
That blue car in the back ground put this setup in for drive train
No no no, never throttle an AC motor under a high stall load like a go-kart or an industrial machine with a TRIAC dimmer, that murders the motor from the 60hz walls of voltage slamming into the windings. Its already a boat with the heavy generator, why not go elegant and use a Variac? As a variable transformer it varies the voltage itself, many consumer units can go from 0 to 250 volts and cost about 200 bucks for a 5kVA Variac, plenty enough power to handle this motor and generator. And also, as a big and heavy transformer, they tend to be immortal. I still have an old like 10 to 140 volt Variac that's older than my dad, and it still works flawlessly, the adjustment knob turns smoothly and precisely, and the geared stainless steel display dial rotates smoothly and still correlates very closely to the actual output voltage.
Edit: Never mind, this is a synchronous motor rather than a normal AC induction motor, it did come off a lathe after all.
@@Avetho 38:50 This came out of a large fan
I very much doubt that they would find a dimmer switch rated to 4kw
I think you guys are on to something here.....Drag Race Generators..........it's got a nice ring to it!
1 hp is 746 watts so if you know a hp rating for a motor you can calculate generator power that way. Watts = amps x volts so if you have an amperage rating instead of hp rating you can use that. Its way simpler than a lot of people think. Just be mindful of peak watt rating vs continuous.
On a 3500 watt generator you only have 15 amps available at 220V. A 5 hp motor will draw 17 amps. A 3 hp motor fed the proper amperage (10.2A) will make 3 hp. A 5 hp motor that is demanding more than the generator has will choke the generator down, and it will only make a few amps at best. Thats why the (I'm assuming 3hp) lathe motor is "more powerful" than the 5hp when properly matched with the correct current.
The "30 Amp" plug on that gennie is just meant to match to a 30 amp RV circuit, so is labelled that. It can't give you 30 amps at 220. Most of those plugs are 110/220 and a smaller gennie like that will only keep up with three 110 outlets.
This is actually a super cool idea/concept gentlemen! As both an Electrical & Locomotive Engineer, I can tell you there's 2 options to do this correctly:
A.) Use a single phase 240V in 3 Phase out VFD rated at the max continuous power (Watts) of your generator, with a 3 phase Syncronous motor rated at or more than the Peak Watt output of your VFD/Generator.
B.) Remove the governor from the generator & throttle it like a gas drivetrain, which then converts your generator from 60hz fixed frequency to a variable frequency output. You would then remove & bypass the starting capacitors on that first motor you had. This would truly make it like a locomotive, albeit a VERY old school tech one (40-50s era Diesel-Electric Loco).
The thing with option B is you can't truly come down to 0RPM, as gas engines typically have an idle, so stopping completely wouldn't be possible. So you could either use a big contactor & switch as a sort of 'electrical clutch', or more interestingly wire the accelerator like a gas golf cart where it acts as a starter switch/kill switch built in to the throttle.
Another way to think of it is the motor acts as an 'electromagnetic transmission' to the gen motor.
Being a retired senior electronics tech for over 40 years all I have to say is AAAAARRRRGGGGHHHH!
Always a good time working on a budget build!
Next use a starter motor
Use a VfD.
FJB
Use a 240 dimmer switch for a throttle
Dont give up on this. It’d be sweet in the pits.
🗣️: HEY BRO I THINK SOMEONES TRAILER JUST GOT STOLEN
ME: nahh that’s just cars and cameras drivin by😂
Regarding dimmers: These are synchronous motors, they will only ever operate at a speed that's determined by the frequency of the power source. Since that's 60hz, that's what you get. It's single speed, on-off. Dimmers aren't going to do anything but burn out.
That is an excellent point, I forgot to take that into account.
What about a voltage controller, like a fan speed controller, would that work?
@@wisecampmotorcycles8258 No, you *have* to change the frequency to alter the running speed.
You can drop voltage and make a synchronous motor drag slightly, but it gets extremely hot doing so and will stall in a heartbeat. All you're doing is making the motor draw more amperage until it can't, which is how copper turns to smoke.
Some motors can be rewired in the pecker head for dual voltage 120/240 volt. FYI pecker head is the box on the motor where the wires are attached. Yes that's the name for it. Lol. See if you can rewire that and run the motor on 240 volts. May help with horse powers. There's a diagram on the cover to wire both ways. Google it if need be.
being that it is a 5hp ac motor it should only be 240v unless it is a specialty motor for a specific task that can needs to be 120v. 5hp= 3730w / 120 = 31.08amp.
yes that's what journey-level union morons call it. i have zero respect for those a$$holes.
I'll be the first to say " this sucks, they ain't working on the dragster this week". Instead they are doing a generator go kart. "I AM SORRY I WAS WRONG"! I never laughed so hard at CarsandCamers. Ike bailing on the go kart and John talking 1880 western so flawless! I'm still laughing! HATS OFF TO YOU BOYS!!!
It's a hybrid! Back to the roots loving it 😂
ive missed videos like this
And here it is ladies and gents, I present to you the "Frakengencartor"!
I do believe you two must be truly creative or maybe just a touch insane! Either way, I love this concept!
The difference between a motor and an engine is more semantics than equipment. It is due to the fact that modern English is assembled from parts from other languages. An engine uses energy to generate force. A motor is a device that creates motion.
This was hilarious back in the day we had a Go-Kart with the motor on hinges you sat in it moved the Handle which moved the engine which tightened the belt but if the belt popped off going down the road the spark plug would get you right in the back we used to put people on it and watch them get shocked and laugh our ass off !
Don't give up on it! Still a good idea. Just put a predator 212 gas engine on the back. Maybe a torque converter. A lawn tractor seat with springs. Small trailer to carry the welder. You could still get out on the trail to do repairs. You know you want to build it, we definitely want to see it!
“Does it need lube?” 😂😂
I've got to say, as a railroader, I'm impressed that Ike understands how modern "Diesel-Electric" locomotives operate. Bravo! Great video BTW!
Adding a 3 phase motor and a vfd would give you more control.
Or a simple Variac between the motor and generator, and a polarity switch between the Variac and the motor. There's the throttle and the gear selector! Glad you didn't say TRIAC, lots of people don't realize that TRIAC dimmers kill these kinds of motors, they chop off the leading portion of the waveform, light bulbs handle that no problem but a high stall load on a motor makes the motor jerk worse and worse the lower you go in speed until they destroy themselves. You _can_ dim a fan, well _kind of_ at least, but it whines a lot and gets louder the lower you go as you hear the 60hz buzz and the higher order harmonics.
Edit: Never mind, this is a synchronous motor rather than a normal AC induction motor, it did come off a lathe after all.
1 phase universal motor with triac would be way better bc it would be more efficient
@@mihkus It would be less efficient, but far cheaper. A VFD can control a synchronous motor like this one, because its in the name, Variable-Frequency Drive, as those motors determine their RPM as a multiple of line frequency. VFDs are also expensive, so using an induction motor with a Variac transformer would be optimal, control RPM by controlling torque, and control torque by controlling the voltage of the smooth 60Hz sine wave. But if you use a TRIAC on an induction motor, you'll kill the motor, those control the RMS by chopping the front of the waves off by only conducting at a certain variable threshold and that basically slams the square-wave-like front of suddenly-high-voltage into a device designed to take a smooth sine wave and nothing but.
Or at least a potentiometer
@@SimonRiley115 that will not work
for those wondering,, this is a good example of why you need more than a 3500watt ac generator. honestly a great representation of gas to electric power. the gas engine would love doing this, but connecting a generator to an electric motor to then power the wheels is a good concept for representing power loss factors
British to southerner to welding… 🤣😂🤣. You two are an Odd couple indeed . Absolutely brilliant my good gentleman ❤🔧🔧😎
This is the kind of sketchy entertainment I started watching y'all for. Love it!!!!
Loved the idea guys! You all inspired me to think outside the box again. And I have a few new ideas myself. Thank you all for your time and creativity!
The fact that you use a gas engine to run a electric motor is just funny and cool to make it drive , its a cool build keep up the crazy different builds.
I think with a little more thought and a lawnmower rear-end, you could a great machine. A hydro rear-end would be the best. That would give the gear reduction and reverse as well. This has inspired me so much, I am going to try to build one myself. Have a great 4th and I'll see you later.
regarding the A/C motor ... on / off. Years ago, a friend of mine and I built an electric go cart (we are talking the 1960's here). We got a 12v battery, a transformer to convert 12v DC to 110v AC ... and a thing called a rheostat ... which basically controlled the amount of volts the motor would require. We used an evaporative home cooler motor ... and got it to work. Though gearing was our problem, not a lot of gears available for a cooler motor ... we had belt drive, and there was too much slippage or we would burn up a car V belt, in about 30 seconds ... I think the most it moved was about to the end of a short driveway. But the rheostat worked pretty well.
John & Ike, this is exactly how our 40's go kart works. It is on a fixed throttle. So it runs at idle speed. If you had a DC motor a speed controller you could use a much larger DC motor and would have throttle. I like the concept and would see if you could improve it. It would be quite interesting to see a electric go kart from you all.
Caster also makes the steering wheel return to the center, after taking a corner.
It's actually a hybrid.
the clutching set up is very similar to what was used on a model T Ford. where a person pushes the clutch pedal down to move forward. and the throttle is on the steering column. and the gas engine normally is set at a pre chosen RPM. and the clutch is basically a slipper clutch. that controls the speed of the vehicle.
the electric motor that you guys had. was probably a two speed motor that has a centrifically controlled by a switch in it the motor. because it takes a lot of current to start the motor. so the motor starts at one speed and switches to the other speed after the initial load is gone.
John riding it side saddle was hilarious. LOL.
22:20 This is great! The "clutch" becomes the throttle as the light switch is flat open. Genius!
The hose clamp to hold the pulley on the moter is great 👍 😂😂😂
That power supply solution is so jank! I LOVE IT!!! 😂😂 this is proper old school C&C back to the old days of John's parents garage
Works great! Just ad an alternator a battery then drive the wheels with a starter motor.
Good ideas here in comments.
Idea: plug a variac transformer into generator, plug motor into variac. Variac has control knob that could be hooked up any way you want.
Fun project!
The cart before the Horse would be cool. A sweet ride with a trailer motor in back to power the vehicle in front . Your idea is like the bar stool , also very cool.
Inverter, 2 motors for a E bike , brakes, larger tyres, hitch & trailer for equipment.
C & C you don't disappoint 😂❤ im expecting a part 2.
Boys, I think you just need a variac. Don't you have one hooked up to the lathe? Change the frequency, change the motor speed.
Iv tried this before and the motor kept going into some protection mode and really didn’t like it
a variac controls voltage, which won't work for speed control on an ac induction motor.
You say variac but mean a VFD. Those are 2 very different things.
THIS IS WHAT CARS AND CAMERAS IS ALL ABOUT!!! I LOVE IT!!!
With all the cool cars in the background, yall should do another series, or playlist, covering those. They look super cool!
Always wanted to make one with the motor and electronics from a treadmill. Don’t know if it’d have the torque for an adult, but it’d be fun to try.
Great build. On a 120/240 generator there are two 120v legs. Each one is half the total wattage. So if your generator is rated at 3000 watts, then it’s 1500 watts on each 120v leg. 1500 watts is the max single 120v load. Not enough to run the original motor. There is also a surge to deal with. A 120v only generator probably would have likely worked since the legs are running in parallel and you would have had access to all the watts. Also a 240v motor would have been able to access all the watts on this generator.
The rail crain was the best use of a stored anything, I have ever seen.
I think what you need to make this work is a bicycle gear shifter and chain to switch gears on a separate jack shaft. It would transfer more power to the ground and have climbing capabilities. Especially since you only want the generator to make rescue missions. The belt drive would still be used for taking off in first gear and then the shifting mechanism on a 10 or 20 speed bicycle chain would be the way to go from there with multiple ring gears. Maybe a 2x10 setup.
I’m not sure what is worse… the acting or the idea! 😂
But John’s accent makes up for it all! 😆
LOL. You guys crack me up. Looked like there was a lot of fun making this one taking a turn for the silly and it was hilarious. Thank you for making me laugh.
Reminds me of my first scooter. I talked a neighbour out of it and nothing worked on it. Even the tires were flat. I got the tires patched enough! Had no engine. So I took the electric motor off my Dad's bench grinder and nailed to the scooter. I plugged in an extension cord and went flying down the drive till I ran out of cord! I lived on a circle. I borrowed as many extension cords from my neighbors as I could get and I made it almost all the way around the circle till I unplugged myself! I had a blast on that thing. Not bad for a 6 year old! I'm now 72 and not much has changed!
Definitely need a part two, using a DC "engine" (yes, it can still be considered as an "engine") for a proper attempt. I can't wait for your next video!
These are the builds I come for, the absolute crazy, “stupid” nutty stuff is the coolest! And this doesn’t disappoint!
Whoa, that carburetor tap blew my mind.
Now you can drive the generator to the job site! Cool!
That ending… the Dadbod Veteran might have some stiff competition!!
Put a small trailer hitch on a tool box so you can pull it around the generator would be a cool mobile workstation for drag strips and stuff
You turned an electric generator into a fun generator... What a great job!
The scene at the end deserves an award
1hp is 746w x 5 is 3730w constant, your generator is 3500w peak. a 3.5hp could work just fine!
Like a NC-8 we used to use in the Navy on aircraft.
A lot of big mining dump truck's and trains run a diesel engine generator to large electrical motors on the wheel's 😮😅 thanks for sharing, all the best to yous and your loved ones
Definitely worth revisiting, the idea is doable with a few modifications
21:52 engines could be diesel or hydrogen powered as well.
yall need an rc boat with a pond like that
Just adding steering to a heavy generator was a good idea still a great concept
Get a neat old welder like a lincoln pipeliner or something and make a real show cart out of it that drives decent and welds. Great stuff as always. Thanks guys.
Well its either the fastest generator or slowest cart. Love that cluch/throttle arrangement.
A AC Variac, would work as a throttle, it allows you to control the ac output voltage.
I'm not an electrician either. But the word you were looking for when you came up with "frequency" is actually phase. Which is actually related to frequency. Both phases in a 220v circuit operate at the same frequency, which is 60Hz in the United States. But those frequencies don't line up with each other on a scope. The difference in the match of frequency is phase.
I was a generator mechanic in the army , so I would fix it, even though the go-kart idea is great 😂
Once again, C&C delivers. Thanks guys.
Cool. Consider a 3 phase motor, if the generator even does that. Those don't need a starter circuit; they sometimes still have them to reduce current spikes at start up, but not needed. Plus a throttle that bypasses governor.
As a British person I am half amused and half terrified at the happy slappy t-shirt.
If I wore one in the UK, I'd probably be lynched
this would be an awesome project for some collab with someone like Redbeards Garage or Rather-B-Welding, i know y'all can make this work
You've got to do a revisit on this I would love to see this working good it would make a great addition to your fleet and an awesome vehicle for the swap meet
You guys need a T-shirt that says " We'll put that S#%T on anything"...lol. This concept is great. A pull behind mobile unit for a quad would work as well. Or stretch out a go-kart and mount the welder and generator to that. Love the ideas you guys come up with, they get me into trouble. Not the bad kind, but the FUN kind of trouble. See you guys in the next one. Cheers.
Instead of lugging the heavy generator around now you can ride it genius idea 💡 guy's. And have a happy 4 😊
That has great potential to turn into a repair rig for the trail.
Talk about put it in reverse terry lol with the spring throttle idea but no one els has really even tried this yall still the titans of the fabrication the moment john said was you serious about the light switch im ☠️ this is the funniest vid out so far we learning the language of ike
If I hear you say how rusty it is when it looks brand new is astounding.
Total power is 746wattsx5= 3730W. Your generator is 3500w or there abouts. If your generator was a 5000w then you'd be in business. A 2 or 3hp motor would be easier though
Hell yes to the mobile "engine " generator v2 😎👍
You should wire in a Light DIMMER knob switch to use as a throttle!
I don't think that would work, afaik light dimmers work by basically chopping the AC waveform by only turning on the power when the voltage gets above a certain level, in either direction, AC motors don't particularly like that, doing so to a fan motor you can hear the motor whining the lower it goes until the motor stalls and just jerks in place. I've tried that before. Perhaps an old Variac, one of them boxed units with a big knob on the front, would work best, remove the knob, connect it through a chain reducer to a gas pedal, and boom you've got throttle, but it will keep moving forward at the minimum voltage. The unfortunate thing is, if you get a new one that can do the full 0-250V range, a proper throttle control for this application, it'll run you about 200 bucks, and they're hefty little units.
Edit: Never mind, this is a synchronous motor rather than a normal AC induction motor, it did come off a lathe after all.
@@Avetho 38:50 This came out of a large fan
That was an adventure
this was fun to watch even if it didnt work out as well as planned
I definitely think this needs a revisit in the future. Maybe get a rheostat for the motor? Or just do something different altogether.
I want to see more on the generator go-kart. You could run a few run capacitors or switch it to DC and hook it up to your starter battery.
Engine vs motor!!! Ike for the win!!! Finally someone says it correctly!
Maybe run an inverter on generator and power couple dc motor hubs or power a good dc motor.
Best video guys! Had me cracking up ..really enjoyed this..thanks!
Oh man! I had an electrical contracting business back in the 70’s!!!
I could have really helped you out!
240v has two 120v lines which are 180degrees out of phase
Instead of the pedal clutch try putting a tensioner pulley on the end or a stick with a pivot point in so that when you pull the stick it engages, add a hook and you can lock it in tension mode.
You just built a Prius! Happy Independence Day Boys
Locomotive engineer (train driver) here, I have dreamt about this project for a decade!
I think the switch should be a potentiometer, it's like a volume control. 22:30 Deadman pedal. That's used on locomotives too. Wise choice.
We used a variable speed controller with a potentiometer on an old 6hp 220v air compressor motor we used to speed limit it for our electric can crusher, my dad sat over the ram and fed cans in then used the throttle pedal with potentiometer on it to speed up the pump/ram forward and back. With 2600+ cans per cube a day of crushing is profitable when they are free
A lot of headshaking and I love it!
Awesome video guys. Get a DC motor for it, then you can run the power supply from the generator. 👍
This is neat, i had the same idea when i was younger lol. Maybe a centrifugal clutch would work better for the electric motor to have some slip and engagement
One of those super quiet inverter generators with a 12v outlet. Mine puts out a rock solid 8amps which is more than enough to power a big 12v Dc motor leaving the 120 outlets free for whatever. Nice compact design easily fits into small places
Nothing sucks more than dragging a generator where it's needed. The darned things never rool well. Gear it down to where you can drive it reliably.
Then some brakes.....LOL
Cheers
Terry
*Great Idea for you* Get a roll around white board. That way when you are explaining your plans, you can give us visuals. Love the channel and can't wait to see you again at Busco -The Z cup holder guy lol
Hybrid technology at its very shed best. Great job guys.
This is a good idea. Don’t give up! This is the stuff I subscribed to this channel for!
