Marke is right. All you have to do is short the rotor windings. Take out the brush gear and short the rings. The best way to do this is to get two pieces of copper bar and put them 180 degrees apart so that the rotor is balanced.
I was wondering if anyone out there can tell me how a PWM AC VFD works. In that I mean whats used in the drive to create the pulses (SCR's etc.). Could somone explain how this works.
Thanks in advance
When your sizing your cable for a motor you take the FLA of the motor, and in practice I usually multiply this by 1.25
Ex 1: If your motors FLA was 13A, I would then multiply this by 1.25 to get 16.25A. Therefore you would go with a 12 gauge wire because it is good for 20A.
This is not...
Controlman is right. It do happen alot but it do violate the code. you did do the right thing by putting in new contactors and breaking both legs.
Not to be negative here but jbartos, and tabler had the wrong idea about 220V single phase motors. Both the leads are hot and you do not have a...
