PERMANENT MAGNET STRUCTURE OF CORE TYPE MOTOR

摘要

A structure of permanent magnet in core type motor wherein the portion which a phase control permanent magnet(2) of the permanent magnet(1) is fixed to a rotor is made to flat plain(F) so as to reduce the distortion of magnetic flux according to the influence of the magnet flux(3) generated in the permanent magnet(1) to enhance the accuracy of phase control is disclosed. Thereby, it is possible to enhance productivity and to enhance the efficiency and reliability of the motor.
