【Abstract】 Many speeds motor is a kind of one that has been developed for many years , motor with already comparatively ripe technology, have already applied to all respects of national product extensively now. It run reliable , run with high efficiency , control circuit to be very much simple, easy to safeguard, noiseless to the electric wire netting, initial investment is low, make its play an important role more and more in national product.
This text make deep analysis and design to single winding many speed electronic electromechanical motive. Originally design in the design of the motor of many speeds of single winding of the introduction, about count , count very much, trough count and winding connect choice method and law that should be complied with of way make detailed explanation. And exchange the structure characteristic of the motor and working performance to the small power, several kinds of latest ones of detailed and deep explanation adjust the speed way.
