Abstract

The present invention relates to a magnetic steel embedded hybrid excitation motor. The magnetic steel embedded hybrid excitation motor comprises a stator 9 and a rotor 10 arranged inside the stator 9, the stator 9 is made of a stator iron core in which an armature winding 1 is embedded, and the rotor 10 comprises a rotor punching 5, magnetic steels 6 and exciting windings 23, wherein a plurality of punching grooves are arranged on the rotor punching 5 evenly, so that the rotor 10 forms a plurality of magnetic poles. The magnetic steels 6 are embedded in the sides of the magnetic poles close to an excircle and are distributed alternatively along with the N and S poles of the rotor 10, and the exciting windings 3 are wound on the magnetic poles of the rotor 10 directly and are distributed alternatively along with the N and S poles of the rotor 10 in the clockwise and anticlockwise directions. The magnetic steel embedded hybrid excitation motor of the present invention is simple in structure and low in cost, is easy to produce, use and popularize, is especially suitable for a large-power automobile integrated starter generator, enables the moment density and the working rotating speed range of a system to be improved effectively, also can used as a driving motor, and enables the motor power density to be improved effectively.

Description

technical field [0001] The invention relates to the technical field of excitation motors, in particular to a magnetic steel embedded hybrid excitation motor. Background technique [0002] In recent years, with the rise of the new energy vehicle industry, the vehicle drive motor has higher and higher requirements on the peak torque and speed range of the motor. In order to meet the size of the vehicle and reduce the system cost, the system hopes that the motor has a larger reluctance torque share. . According to the survey: At present, the proportion of the salient pole reluctance torque of the motor developed by major motor companies at home and abroad and the torque generated by the permanent magnet steel are generally less than 45%. If the ratio can be further increased, the system cost can be effectively reduced and the motor power can be improved. Performance and system matching. In the hybrid vehicle system, the space is tight, and the requirements for the power densi...
