3-Speed Single Phase Motor Wiring

[Clark Yu]

Hi, all.

I need your expert help in creating the internal wiring diagram of the motor with the following information we retrieved.

I have attached a diagram showing:

A. Motor external wiring diagram
B. Wiring Resistances
C. My diagram for main winding only

I am missing how to include the orange and yellow wiring to the main winding (assuming my diagram is correct; if not, kindly correct).

Thanks in advance.

Best Regards.

Unless I am missing something, orange is connected directly to blue, yellow is connected through the 51 ohm capacitor winding to brown. Supply on blue and brown makes a regular PSC motor with the (blue-brown) winding fed directly from the supply and the (yellow-brown) winding fed via the capacitor. White and red are the taps for the other speeds.
