Показать описание
This video will walk you through how to determine the various components of a single phase motor with an ohmmeter, and how to connect a dual voltage, single phase motor for operation on either 120 v or 208 v.

It's a long video, but it covers everything you need to completely understand the initial wiring on our single phase motor trainers. Hope you enjoy it.

Determining Components with an ohmmeter: 25:15
Low Voltage Connection: 40:07
High Voltage Connection: 53:46
How you're going to screw up the polarity of the Run Windings: 42:56

this helped me understand the wiring of a six wire 240 volt motor and how to reverse it, i just wasn't understanding the wiring and you made it seem easy

So what wod cause a electric motor to not engage, I take the belt off I can operate the motor, to add a load it shorten out the fuse, I think its the capacitor!! Any help will greatly be appreciated

I guess you could connect the two run windings in parallel and measure the inductance, swap one of the windings around and measure it again. Select the configuration with the highest inductance.

Cool! I just had a question about this on my c of q today
I think it was how to reverse a dual voltage single phase 120/208
I put 5 and 8
Hopefully its right!

High voltage wiring line 1 line 2 but what happened to the neutral

I'm a little disappointed that you glossed over the fact that the start coil would not get 120v in the 240v configuration, due to the series/parallel wiring. It would get around 100v.
