Determining polarity is almost a black art but this video is probably the best explanation I have come across. It combines the practical steps along with the theory in the form of circuit diagrams thereby reinforcing the concept. Well done that man !
thank you!!! I bought a used dayton 3 phase on friday…just 9 yellow wires no marking…just went thru your procedure…now working fine. again, thank you for doing this video👍👍
8:05 I did it a third time on (3) different motors and I realized that seemingly, you can always determine which wires are 8,5 & 2. I used Baldor motors; 1,2 & 5 horse. I employed 19VAC for all my tests.
Hey Zack, thanks for the great videos. I have a question, when identifying polarity, couldn't you put a jumper from F-I and then check continuity values between G-F-I to determine which is which' or does that not work?
Hi thanks for video explaining clearly however I am having issues with my bench grinder motor it has 3 wires all tests fine new capacitor installed the motor spins at around 20% speed and buzzez realy bad what would you suggest I have struggled to find any further information regarding this
I'm just a machinist, but your video has helped me establish that it is a WYE motor, but the 6v battery isn't giving enough deflection for my cheap meter to register. So I wanted AC source like you used, so I can use my digital meter. Thanks@ZackHartle
I tried using a VFD to produce 20V (20V is the minimum voltage) and it didn't work that great. The rotor in the motor started spinning and my readings were fluctuating greatly; what did you use to produce the 15V? and... can you recommend something cheap? I recently became a maintenance mechanic and all of this is new to me. Thanks in advance!
My only question and it's my ignorance. When you are applying a voltage are you using a AC or DC power supply? Guessing AC but would like to be sure. Thank you.
@@mattozx6rr I am using a Variac which is a variable autotransformers, but you can easily use a doorbell transformer or small control transformers too. As long as it gives you a small-ish AC voltage. I always like to use between 12V and 24V

Thanks so much. Appreciate it!
thanks zack got a 100% doing my lead id exam
by watching your video
Hands down the very best illustration of how to do this process. Thank you so much!

Absolutely the best video I have seen on this. You make it simple to understand. Thank you for your efforts in making this video.
Glad it was helpful!

VERY INSIGHTFUL..... Asante Sana (Thanks very much)
Very good explanation thanks bro
Thanks for your video, it was a great help with a similar situation, greetings from Mexico
Glad it helped!
Wow! great explanation..thanks
I appreciate sir , your explanation is perfect....thanks alot ❤
I was looking for this. You da Man!
Clearly video, you are the best, Thanks
very good. explication interested . you are number one.
outstanding video!

Not too sure. I don't think I can help with that one
Helo. I have a motor like this, Is this motor will work for delta connection? I tried but the result is giving me high amperes.
So if we use 7 values for each node then with extra ground then we had 64 bits by dividing voltage into 7
What AC power supply do you recommend for a novice, learning the basics?
Doorbell transformer
@ZackHartle so I can clip this to the windings, and then check deflection?
@@ZackHartle I have a 440 3 phase lathe I'm installing, but the motor leads aren't marked. I need to install a VFD and need the motor at 220v 3 phase.

Can someone explaine why polarity is additive or subtractive in this video?

That is correct. It has to be an AC supply!
@@ZackHartle Are you using a computer power supply or something else?

@@ZackHartle Thank you. I have a variac just wasnt sure I could use it.
Very good point raised
So if 3!/2! ×3 = 196 variable then 64 bits is easy
