Abstract
The invention discloses a claw pole type permanent magnet synchronous motor, which comprises a housing case with asymmetrical pole claws and a front cover. The motor is supplied with direct current. A middle shell with symmetrical pole claws is arranged in the housing case. A wire frame and a wound coil wound on the wire frame are arranged between the housing case and the middle shell. A permanent magnet rotor with a gear is arranged on a center shaft of the housing case. A plurality of gears meshed with the permanent magnet rotor and an output shaft are arranged on a gear shaft of the middle shell. An actuator is arranged outside the motor and connected with the wound coil by a connecting wire, and can convert input direct current into certain frequency-controllable pulsating current. The permanent magnet rotor is meshed with the gears and the output shaft to form a speed reducing gear system. The motor has the characteristics of low power consumption, high moment of force, direct current power supply capability, running reliability and convenience of use. When the motor is run under certain frequency, the rotating speed of the motor is not influenced by voltage and is kept constant. When loaded, if the motor is overloaded or locked, the coil of the motor may not be burnt out.
