There was a thread a year or so about motors designed for 60Hz being used on 50Hz and vice versa. One way works, one way does not. I cannot recall which.

Capacitor start gives higher starting torque, but split phase is less expensive and gives a more gentle start.? The black disc activates the the start switch, it will snap toward the fan when the speed is sufficient. The brass weights you see close to the fan move outward at speed, and warp the black metal ring. It changes shape in a snap, and pulls the black plastic ring toward the fan. This releases the pressure on the brown lever that is attached to the start switch.? This design is used on many makes of motors, and in almost every case the ring does not touch the lever when the motor is at speed.? Does the motor refuse to start, or overheat?
