Abstract

The invention discloses a multi-index synchronous optimization method and system for an external rotor switch reluctance motor. The optimization method includes the steps that a power constraint condition of an electric vehicle to awheel hub motor is established; a performance index and a structure parameterof the motor power are determined according to the power constraint condition; a motor structure size constraint condition of each structure parameter is established; an orthogonal table of each structure parameter is determined according to each motor structure size constraint condition, wherein the orthogonal table comprises a plurality of levels and corresponding values for each structure parameter, and a first set of orthogonal experiment is carried out; a multi-index synchronous optimization objective function is established according to the results of the first set of orthogonal experiment and the performance index; and an optimal solution structure parameter combination is determined according to the multi-index synchronous optimization objective function and the level of each structure parameter to achieve the synchronous optimization of multiple performance indexes.

Description

technical field [0001] The invention relates to the technical field of motor optimization, in particular to a multi-index synchronous optimization method and system for an outer rotor switched reluctance motor. Background technique [0002] Scholars at home and abroad have conducted in-depth research in this field for the design of the structural parameters of the in-wheel motor. Sheth NK et al. selected structural design parameters that can improve the average torque of the motor, and studied the influence of different air gap parameters on the overall torque waveform of single-phase excitation motors. Jawad Faiz et al. designed the stator and rotor structure parameters of a 12 / 8 single-phase excitation switched reluctance motor with torque and efficiency as the design goals. Deng Zhiquan et al. studied the influence of the winding structure on the midpoint voltage fluctuation of the motor for the bearingless switched reluctance motor, and designed the motor winding struct...
