[GreenKeys] KSR35 : What kind of motor is this?

[Bruce Gentry]

The motor is synchronous with split phase starting if there is no start 
capacitor or  capacitor start if there is.  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?
