High-reluctance torque driving motor of hybrid electric vehicle

Abstract

The invention provides a high-reluctance torque driving motor of a hybrid electric vehicle, and belongs to the technical field of vehicle motors. The permanent magnet synchronous motor is characterized by comprising a stator iron core, permanent magnets, armature windings, a multi-tooth-shaped block rotor, a magnetism adjusting winding, a non-magnetic-conductive rotor iron core and a shaft; 12 stator poles with the same width are arranged on the inner side of the stator iron core, and 8 multi-tooth-shaped block rotor iron cores capable of conducting magnetism are placed in the arc-shaped groove of the non-magnetic-conducting rotor; one magnetism adjusting winding is wound on the stator iron core every other stator pole, and armature windings are wound on the rest stator poles; a permanentmagnet is embedded in the middle of the pole body of the stator pole wound with the magnetism regulating winding; and the multi-tooth-shaped block rotor iron core is obtained by cutting a plurality ofU-shaped grooves in an outer arc line of the block rotor iron core, and each tooth groove of the multi-tooth-shaped block rotor iron core is filled with a non-magnetic light material. The multi-tooth-shaped block rotor iron core has the advantages that the multi-tooth-shaped block rotor iron core can change an air gap magnetic field of a motor, weaken harmonic waves in counter electromotive forceand reduce torque pulsation of the motor; and the embedded permanent magnet can improve the reluctance torque component of the motor.

Description

technical field [0001] The invention relates to a high reluctance torque drive motor of a hybrid electric vehicle, which belongs to the technical field of electric vehicles. Background technique [0002] Today's social environment is deteriorating and energy shortages are becoming more and more prominent. The whole society's requirements for energy saving and environmental protection are promoting the development of new energy vehicles. As a representative of new energy vehicles, electric vehicles have gradually become the main direction of development. Drive motor is one of the key technologies to be studied in electric vehicles. [0003] In the permanent magnet segmented rotor switched flux motor, the permanent magnet is used instead of the DC excitation winding, which reduces the excitation loss, but has the disadvantage that the excitation field cannot be adjusted. Therefore, attention is paid to the drive motor with hybrid excitation, and the magnetic field is control...
