SALIENT PERMANENT MAGNET MOTOR, MANUFACTURING METHOD THEREOF AND ELECTRIC VEHICLE COMPRISING THE MOTOR

摘要

A salient permanent magnet motor is disclosed, which includes a rotor ring formed with a circumferential grooves in its inner periphery, and pole shoes and permanent magnets fixed to the inner periphery of the rotor ring by a glue which is originally dispensed in the circumferential groove in the rotor ring and then flows under capillary forces into a glue gap formed between an outer periphery defined by the pole shoes and the permanent magnets and the inner periphery of the rotor ring. A method for manufacturing the motor and an electric vehicle comprising such a motor are also disclosed. The rotor according to the disclosure has a higher output torque and a larger operation speed range.
