Abstract
The invention relates to a hybrid excitation brushless claw-pole motor. In the motor, a permanent magnet and an exciting winding form a magnetic field commonly in an exciting mode of combining permanent magnetism with electric excitation, so that the defect that the magnetic flux of a permanent magnet generator is nonadjustable can be overcome, and the capacity of the exciting winding also can be reduced. Air-gap magnetic flux density and the power of the motor are increased, the efficiency of the motor is improved, and the low-speed output characteristic of the motor is improved under the condition that exciting current is not increased. In addition, due to the adoption of a brushless structure, the running reliability of a system is improved. The motor comprises a machine shell, wherein a rotating shaft and a stator are arranged in the machine shell; the stator consists of a stator core and a stator winding; a claw-pole rotor is arranged on the rotating shaft, and the permanent magnet is arranged between claws of the claw-pole rotor; and the exciting winding is arranged on an exciting support, the brushless structure is adopted, and the exciting support is fixed on an end cover of the machine shell.
