converting DC air conditioner indoor unit fan motor for using in AC system

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?

Depends on the type of motor and the operating voltage. What are they ??

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

There are a variety of small motor-rated SCR drives (not cheap) that will h andle 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? T hat 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 y ou need AC for the electronics and DC for the motor - then whatever kluge y ou design will need to be inside the system at the motor feed. Still-and-al l, it should all fit into a standard 1900-box when done.

Presumably the motor drives a fan. If so you can make use of the speed/torq ue curve and use a capacitor on the ac side of the bridge to handle the mot or voltage reduction.

Or plug the AC system into a DC converter.

Unless the controls require AC.

You did not provide enough information to get a really usefull answer. One of the most important things is the voltage required. It makes a hugh difference whether 12Vdc, 24Vdc, 120Vdc, 220Vdc or some other value is required. Another thing is the type of the motor involved. The type should be on a plate on the motor. Best of all would be the datasheet of the motor.

Yes, as Petrus said you have to state the voltage and the type. Most of them are BLDCM so you cant use ordinary DC.
