I need help. I have a 3phase. I did a conituity test between each leg. The meter beeps on all. Normal? I did a ohms check. One leg =8 another=12 another 31. I did a supco megger to each leg with one tester and the other tester to casing. It shows good. My question is simply do i have a short in this motor?

Video could have been waay better if you would slow down and show your work! Better camera position

This is the video I have been looking for for years. Thank you for putting this out. It really helped me.

Thank you for explaining this properly, took me 6 videos to find you.

so is that mean there are 6 separate winding in there? I have heard of delta and Y connection but not star, but of course I got a lotttt to learn. thank you for your video

I don't know what you're doing nowadays, but this was a great video. For what it's worth, your video is the number 1 return in Google for troubleshooting a 9 lead the phase motor. Thank you for a very concise explanation!

Excellent video, super clearly explained!

Is there a tolerance for deviation of resistance from winding to winding for the single coils?

I was always told you need a megger to do this test correctly

thank for scheme

Great explanation!!

That’s actually a little high for resistance on an ac 480 or 600 volt motor it should really only read 3 ohms or less most normal reading is .5 ohms

Hi everyone. can someone tell me what could be causing high amps on two legs only ??? motor voltage = 460 motor amps rating = 283 Line 1 voltage to ground = 278 Line 2 voltage to ground = 281 line 3 voltage to ground = 280 Motor connection are secure , there is no loose connections. we Megged the motor and cables and shows over 2k megaohms . motor amps when running Phase A amps = 280 Phase B amps = 292 Phase C amps = 285 as you can see only one phases is below the name plate rating but still little bit to high. There is no enough voltage imbalance to explain the high current on the two phases . why is the high current in two phases only ??? motor was rebuilt recently. Anybody has any idea what our problem is ??? Any suggestions ???

Appreciate.thanks

Hello there, thanks for making this video. I just wanted to comment about the inductance values you mentioned. Like you said it’s helpful if the value in Henry’s is known. If it is then the inductive reactance can be calculated by XL = 2(pi)fl, then that value can be squared off along with the resistance value and added together then square rooted. The result should give us the Impedance value.

So is low voltage 240 single phase or 240 3 phase?

👍🏻

Bloody awesome Video man! So clearly explained that even a dumb mechanical engine Bilder like me can understand that electronic witchcraft 😂🎉

I understand your theoretical side but when you measure practically how do you know which wire is which, looks very confusing did not understand your practical side.

thanks so much.....Paul

Being an apprentice in motor controls, I ask for low voltage, why do they want you to short 1&7,3&9 and 2&8? Why not connect to 7,9,8? Thanks for your excellent teach!

I appreciate the information, it helped me to determine the correct numbers on the wires . The little metal tags were very hard to read . So i used this method and checked the condition of the windings . . What a learning experience especially trying to get the motor to run properly with a phase convertor. I going to buy a vfd and use it on the bridge port mill. Thanks

I didn't see clear the way you are testing What can I do to get it clear

Why didn’t you get a megger I just got the Klein and this thing is great.

very well explained.

If the wires is not marked how to determine which wire is 1-4 3-6 etc??

Love the step by step instructions on how to check the windings. It really helps make sense of all the "book learning" I've done

Good video. All coils are used irregardless of the supply Voltage. High voltage uses the +3 method for connecting the leads together and low voltage connects the windings in parallel with each lead connected to 1 and 7, 2 and 8 and 3 and 9 with 4-5-6 connected together just like 10-11-12 are from the factory. Hig voltage connects windings in series.

thanks very good. i am from Algeria. i am glad to see you . we'll I Will ask you about. when we make start high power . star low power. and when make delta high power .and dalta low power . and thank you very much.

👍👍

Helped me on my test

Wouldn't you have continuity between leads 1,2,3??

Great video with explanation, thank you for drawing the diagram FIRST!!!👌🏿

You saved me from spending like $800 on a new motor. Thank you!

At school they have us megg between 1 and 4. Doesn't that seem wrong?

You need to use a megger for a AC Gen.

What of the leads had no numbers????? Please do a video on that 🙏

how to convert it in 1 phase?

Good afternoon , is it motor baldor?

Hello, how are you? I am a young man. I am 24 years old. I work in the field of repairing electric motors, Bobbinage. I would like to work with you. I have experience and fast work. This is my number 49145985. Thank you. ملاحظا

Thank you for that sharing sir.

Your video just taught me that the hvac tech charged me for a new motor when the motor I had was perfectly fine. Then he tried to leave with the "bad" motor. The tech was trying to steal a perfectly good $800 motor.

I'm interested please help me

really good video testing using a multimeter. Sadly i was hoping for a video as good as this video was made using a digital insulation resistance tester

Aren't you supposed to megger the insulation?

Very clear and instructive video . Thank you so much !
