Great video Keith and very good speaker. 😀

Hey Keith, I'm looking to buy a 1HP 3 phase motor with 1440 RPM for cutting cast iron pipes on a saw machine. There's no coolant used and the environment is very dusty with the dust being metallic hence conducting. Which enclosure type should I go for? Also would appreciate if you could suggest a good motor brand for my application type. I'm from India by the way. Thanks.

Thankyou

Very useful information Thank you

I have not looked through all your videos yet but all the settings on an overload are a bit confusing. The tiny explanations in the multi language packet sometimes refer to a symbol that doesnt mean much to someone learning or uninterested. Leads to guessing at adjustment. Thanks for your videos.

I have a late 60s 2 speed motor that has been swapped to a drive. When slowing in an unloaded direction (possibly reverse loaded for slowing down with a regen resistor) it chatters and hiccups some runs. I believe the motor is high slip but low info on the data tag. Also possibly a gear box problem. Any suggestions? Thanks for your video.

YT algorithm seems to find these great tubers..

Are most VFD's capable of converting single phase to three phase? It looks like you just use L1 and L3 as the input, then oversize the VFD, is that correct?

VFD's Can also be used to create 3 phase supply for motors from a single phase input.

Keith, how about details around removing the grease drain plugs. How do we access grease drain plugs without removing the fan housing covers? Also if the motors should be running when we grease, how is it safe to do this with covers removed? Why do motor manufacturers make it so difficult to remove the grease drain plugs? Does this mean they don't want us to grease them? Thank you

does VFD reduce overloading?

Nice and important video

How I run three-phase motors on single phase: line and neutral from single phase is connected to connection 1 and 2 on the three phase motor, and then I will take a standard run capacitor and connect it to line two and three on the motor

If water hole motor is 13.7 amp. (23.7 amp is what is on the motor plate written) what amps i have to set on overload switch please?

Excellent video, very informative! Thank you Keith.

Motorcycle starter... Bike started intermittently. Cleaned up the wires/insulated bare spots, put it back together according to the manual. Now operates in reverse. Help...?🤔

Hello I bought a counterclockwise 48VDC NIDEC 140-22-4004 for a steering hydraulic clockwise Vickers pump. Any chance of changing the motor rotation?

Why on my motors is the copper plates wearing out and not the carbon brushes ?

Can you use vfd on a farm duty motor with start up capacitor? I was given one and wanted to purpose it fir a belt grinder.

Hi, if we connect motor either delta or star with vfd what are the differences between them

Joked...I was expecting how to do,,procedure...lol

Thankyou

all good advice . well done guys

Thanks Keith!

Thanks Keith

Thanks Keith

Thanks Keith!

One smart advice from smart guy Thank you

I work at Mac & Mac Electric and well this is quite useful information!

Great video! Give us a video with info about brake resistors no one talks about them

Thankyou sir

If you run the motor at too high speed, its torque can decrease to the point when it can't maintain rotation and will straight up stop completely, coils will draw too much current and damage VFD and themselves, potentially causing fire. Also if you run it at really extreme speed, and this motor is large, its rotor can just tear itself apart, causing massive destruction to whatever rotor's debris hit.

How to select the right grease? Thanks

Thankyou

How would I know if a motor is of a SRM type? WOuld I need a special VFD for such motors?

How to remove "frozen" brush cover on a 1940's Black & Decker circular saw?

Great video! Thanks. I put together a little strobe light kit back in the '70s, and the first time I tested it, a capacitor exploded. (Maybe I put the wires on the wrong terminals?) Darn thing never worked, and no one in my family suggested we replace it after a careful look at the schematic. (To be fair, there were shreds of paper *everywhere* inside the box. It looked hopeless.)

Thankyou sir

Thankyou so much sir

Glad to see that IEC motors are available

Can I use a vfd with a synchronus servo motor, ignoring the encoder feedback?

Thankyou sir

Hello You know what? I am a regular viewer of your CZcams Channel. I have seen all your videos and your content qualities are very good. I learned lots of things from you. Your channel has great quality contents but still it is not delivering its right audiences due to SEO problems. You should focus on your SEO so that You can get a big fanbase. Thanks

can you import an IEC motor from Europe?

I have a question for you. I have standard 110 in my garage and I have a 3 phase motor I want to use on an old drill press. The motor is manufactured by “Brown & Sharpe and its 3 phase Alternating current. There are nine, all painted black, wires protruding from the motor. Three sets of two have been twisted together and there are three left alone. Their numbers are 1, 2 & 3. The motors information plate on the exterior of the motor shows that it can be wired 208-220 or 440. Under the 208-220 it shows the following: 3 lead motor 1-2-3 6 lead motor 1-2-3 6-4-5 9 lead motor 1-2-3 7-8-9 4-5-6 So, can my motor support the use of a VFD and if so how do I wire it??? Is my motor VFD compatible? If so, how do I wire it???

Hello, is there a VFD that works with dc booster pumps, batteries and solar panels during power outages.

Would this video be helpful in knowing if you can use pulse width modulation with a motor? I think its an analogous situation. New to electronics, please help

Thankyou sir

Water pump (thanks to rubber garden hose) decided to flood basement this night. Luckily? - found capacitor blown up in morning, and 10cm of water all over basement. :)

I see every video of you sir you are very great sir
