How long you can run it for a full charge?
Haven't tried it for long but max I went was 10mins and still had 75% battery
What voltage for speed controler and wattz
Hi sir😊 The other type or the name of the company that is compatible with the suspension system of this car, or another type for another car model that is compatible with our car.
yo its me again can i contact u on discord for more information. Im making a project
Why every one racing in the back ground !?
Lol i had recorded this video outside and I live right next to a busy road, also had sped up parts of the video while editing
its kinda late but what specific kind of car alternatior do u use, how much rpm its have ?
I wouldn't be sure on the actual specs or the rpm but you can use any alternator
@@rextech42 00:34 wdym for test only ??
Ok... what happened to the 2 wire rotor leads? Care to share the speed controller spec?
It's connected to the 12v car battery just to energize the electromagnet, controller is a 500 watt 36/48v brushless
fundamentally a motor and generator (yes generator) are the same. A car alternator is a 3 phase motor/generator with a field winding that needs to be energized. When used as a generator the device produces 3 phase A.C. which is rectified by the diodes embedded in the device. Alternators are not especially good as motors since they require 12 V (Usually) at 1-4 amps wasting as much as 48 watts in the field winding.
I'm just showing that it can be done
@@rextech42 I appreciate your work. Other channels have demonstrated how to get a massive permanent magnet in there, but that's an extra cost, albeit a potential upgrade path.
Great Video! Would a 24V alternator be stronger / spinn faster?? If it was connected to a 24 volt battery ofcourse
No probably be slower but might have higher torque, it has to be driven by 36v and up
Thanks
What size controller did you use.
500watt 36/48v
Are there 3mm thick pipes or 2mm? Cause i have plenty of 2mm but no 3mm ;(
You can use 2mm but 3mm and above should be used for the main column
@@rextech42Thank you very much! I'm kinda new to this whole weld/diy thing but you did a great job showing how it's done it's an awesome ideea with the one side handle and the other side the air piston I can't wait to get started😆
@@YagrumBagarn thank you very much for the appreciation 😊 I'm glad you liked the video
How to retract the brushes I'm stuck😂😂
Pls send advice
There's a tiny hole for a pin to slide into, push the brushes down and slide a pin or a drill bit in to lock them in place. Once you've assembled everything, pull the pin
It's missing few nuts 😊
😂
just want to know why did you change it was it making noises Strut Mount ? please can you let me know
It was a customers car that had failed inspection, but yes they usually start making a rattling or a thumping sound when they wear out
Very impressive 👏
Thank you so much 😀
Link to controller and throttle please

Why are you soldering wires 🤦♂️
Are you supposed to superglue them?
@@rextech42 Crimped connectors
Will crimp them for next projects thanks
@@rextech42 ok 😒
@@rextech42 crimp over solder wtf...
It would be interesting to see what the peak power/torque output is, and also how much of a steady load it can deliver without heating issues.
I will be trying to put this on a scooter or a bike to see if it's able to move it, will be making a video soon
Steps on how to do headlights ?
Will make a video and post it soon
thanx
No worries
Is the car battery enough to run it? How much time can it run?
The car battery is there just to keep the electromagnet live, main power to spin the alternator comes from the 2 drill batteries
@rextech42 nice work man. Just a quick one...how many AH must the "electromagnet" be?
@@NiteshMahabeer not sure but I've heard they take 12v and 10amps to work properly
@@rextech42 thank you very much
@@rextech42 thank you
Just need to understand for me, 1) Does your controller is supported with/without hall sensor ? 2) If not then now you have fix magnet field inside so how your controller understanding the position of south & north pole without connecting any hall sensor wire from your controller? Because I also made the but my alternator only jerk twice thrice & stops please help me to make it successful bro. Tx in advance.
Hey the controller does support with/without hall sensor I think that's the reason why it doesn't need hall sensor to operate
Good working bro 💯
Thank you 😊❤️
No requires torque values? What model Swift is this? Thanks.
Don't really need to torque it as long as you know how tight it has to be, not sure of the exact model sorry
@@rextech42 How will you know if the shock mounts are for replacement?
Strut mount ka price kya hota h 2 piece ka
Bhai depends where you are buying it from
@@rextech42 Nexa wale 1 piece ka 1600 bta rhe! Chandigarh me

What you laughing at?

Nicely done. What size tubing and bolts are you using? I'm having some trouble making mine
Id of tube is 10mm od is 12mm, bolts are m10 x 1.5 x 140mm
@@rextech42 Awesome. Thank you
No worries
Hello sir. May i have the measurement sir?
There isn't any specific measurements you need as it all depends on how big you want the press and also how big the drill is. Let your imagination be your measurements 😊
Do i need wheel alignment after changing shock mounts? Thanks
No you don't need to unless your hub bolts have camber lobes
Thanks
@@noelsimbulan5455 no worries
Por que no usan la guarda, ya que es un elemento de mucha seguridad ??
We don't purposely remove the guard, it's either been given to us like that or the guard has been lost. Sometimes it's easier to cut steel without the guard
Can you directly power the alternator from the battery, bypassing the controler? Or will that fry the whole thing?
No it's not possible as the alternator is a 3 phase motor so you will need a controller to run it
Hey im wondering if this could be used in a car audio setup my car (2019 Toyota Camry) won't take a HO alternator because of the new ONBUS LINBUS electronics build which is where the cars computer is built into the alternator housing so I can only upgrade my battery system UNLESS I can figure out how to do something like this to power my lithium then i could run any setup I want to this would be able to power a lithium Bank really well i just don't know enough to do it maybe if you made it with a different type of switch kind of like a bass knob but for the speed control im just thinking out loud and asking at the same time im literally clueless and need help to figure it out any advice would be greatly appreciated
I'm not sure if it would work but maybe someone who has more electrical knowledge might help?
Good bro 💯
This doesn't "power" anything, it's a variable speed electric motor
After watching several videos I have no idea wtf to do still
What part are you stuck at? I could walk you through it
@@rextech42 actually watched the video a few more times and got it thank you!
No worries
Nice bro
You will need some basic knowledge of electrical
Great video, I like how you make it look more simple than the other videos, but as a 13 yr old that loves automotive and engineering I want to change my dads old alternator into a motor and I want to know before I start, how do you know if a controller works with a sensor-less motor.
Hey thanks for your comment, before buying a controller, read the full information about it and make sure it says that controller works with sensor and sensor less motors.
@@rextech42 thanks God bless
Buenas noche hermano excelente herramienta gracias por compartir saludo y muchas bendiciones desde Venezuela Edo Carabobo Ali Molina 🙏
Really appreciate your comment thank you 😊
What amp output is the alternator? Do you need to match it to the controller? I'm thinking of making one for a diy, electric powered go-kart. I can get a second-hand 180amp alternator for around £40.
Doesn't really matter how many amps the alternator has but what matters is how many watts it can produce, so if a alternator can produce 2000 watts, that means a 2000watt controller can run it. I'll be making another homemade motor using a faulty car alternator soon so stay tuned
@@rextech42 Ok, I've subscribed. A quick google search says - "If you want to convert amps and volts to watts, simply multiply the amps and volts." - So my theoretical 180 amp alternator x 12v = 2160 watts. Would that mean I'd need higher than a 2000 watt controller? (sorry for the stupid questions)
Nice bro
incredible job, thanks for your idea
No worries
You mention the possib of a 1000 W controller but I can find quality controllers going up to 500W. Do you any secret squirrel path to a quality supplier (Ebay ) of 800 W or 1000W BLDC controllers , espec those that will work without a Hall line. Do you know if it is practical to add extra MOSFETs inside of an existing controller in // to the existing ones to achieve a higher rating if I can't find that 800 W or so controller. Thanks in advance . Tim F in Nz.
The controller I'm using is from Ali express, there is controllers that is rated for more than 1000w, but you have to see if they can be used with non hall effect sensors as in motors that can run without hall effect sensor
@@rextech42 Thx for very fast reply. I know aout the missing HE sensor issue. I refuse to deal with Ali vendors but I can see if I can get a PP quote from an Ali vendor. I have had that done before on completely different materiel. As the Aussies say - ya blood's worth bottl'ng.

I need to take your car for a ride brother 😂
Deal
Rex mahn talented young man 😂😂
how powerful is this motor? 1kw? 10kw?
Around 1kw
Nice bro
THIS IS VERY SWEET~ VERY SWEET
Thank you, check out the brushless conversation I did on a alternator on my channel
Nice bro
If you put some capacitors between the battery and the load, with the battery looped to the capacitors and the motor looped to the capacitors, it will take the load off the Battery and not heat up the battery or motor as much I think.
Rex Tech Looks like I found it and your other nice builds to review. Thank you.
No worries :)
Amazing work keep it up
