Abstract

The invention relates to a hybrid excitation multi-phase reluctance motor and a power generation system, belongs to the field of motors, and solves the problem of narrow adjustment range of the magnetic field of the existing hybrid excitation reluctance motor. The air gap magnetic field is adjustable and the excitation loss is reduced by using the hybrid excitation electromagnetic structure of joint excitation of current and permanent magnets. The excitation winding and the armature winding are both arranged on the stator, and there is no brush or slip ring on the rotor. The system has high reliability and convenient maintenance, and the structure of the motor is changed by changing the winding mode of the excitation winding and the armature winding and the permanent magnet distribution mode. The system is suitable for the fields of power supply of airplanes, ships and locomotives, power generation of new energy sources such as wind energy, solar energy, ocean wave energy and the like,flywheel energy storage, electric vehicle drive and the like.

Description

technical field [0001] The invention relates to a hybrid excitation multiphase reluctance motor system, which belongs to the field of motors. Background technique [0002] The air gap magnetic density of the hybrid excitation motor is jointly generated by the permanent magnet and the electric field winding, and the magnetic field change required for speed (or voltage) adjustment is partially realized by the auxiliary electric field winding. When the direction of the electric excitation magnetic field is the same as that of the permanent magnetic field, the air gap magnetic field is strengthened; when the electric excitation magnetic field is in the opposite direction to the permanent magnetic field, the air gap magnetic field is weakened. Therefore, by adjusting the magnitude and direction of the electric excitation winding current, not only the field weakening control of the motor field can be realized, but also the field increase control can be realized. The hybrid excita...
