SYNCHRONOUS MOTOR WITH IMPROVED STARTING CHARACTERISTICS

摘要

A synchronous A.C. motor having two sets of stator poles disposed in circular spaced alternate series, a rotor disposed therein with alternate pole areas equal in number to the stator poles which provide two paths for rotor flux when the motor is quiescent, and the stator poles being made such that the normally lesser dominent flux path is dominent causing the rotor to assume a desired starting position while not causing imbalance when the motor is operated.
