hi
i have a panasonic 60w dc motor for air conditioner that i wanna use this motor for an AC system so i need redraw wiring of DC motor for using it on AC system so i need help cuz i dont know how must done this job?


Pretty basic: Rectify the AC at the motor. You will need a heavy-duty bridge rectifier capable of handling the current required, you may need small motor caps to reduce motor heating and rF noise and you may need to reduce the voltage to the motor after rectification.

There are a variety of small motor-rated SCR drives (not cheap) that will handle the voltage reduction, and a few 0.01 uF, 600V mica-dipped caps will handle the noise.

What voltage do you need for the motor? And what is the current required? That would be your starting point.

These two items you would put on the AC side and trim until the DC voltage from the rectifier was correct for the motor. Where this gets dicey is if you need AC for the electronics and DC for the motor - then whatever kluge you design will need to be inside the system at the motor feed. Still-and-all, it should all fit into a standard 1900-box when done.
