[GreenKeys] 28V MITE Myth or Real ?

[Bruce Gentry]

The outer part of the rotor in a Mite motor is hard steel. The motor is 
capacitor start and run two pole, and is wound to bring everything close 
to saturation. It starts as an induction motor, and as it approaches 
synchronism the rotor becomes magnetized and locks in to synchronous 
speed. Motors of this design run hot and are of poor efficiency.
