Indirect Vector Control for Air-gap Magnetic Field of Five-phase Induction Motor Through Dual-plane Synchronized Rotation Transformation
摘要
Abstract
In five-phase concentrated full-pitch windings induction motor system, by injecting the special third harmonic current for a quasi-square air-gap magnetic field, the ferromagnetic saturation can be reduced, and the utilization ration of motor’s ferromagnetic material and torque density can get improved. In this paper, the vector control mathematic model of five-phase concentrated full-pitch windings induction motor in d1-q1-d3-q3 coordinate system is built. To satisfy the requirement of a quasi-square air-gap flux, the relationship between the fundamental and third harmonic component of the air-gap flux linkage is analyzed,and the direct and quadrature current components in the third harmonic plane as non-linear functions of the fundamental are calculated. On the basis above, the third harmonic current injected method to improve the motor’s air-gap magnetic field is proposed. Finally, simulation by Matlab/Simulink and experiment is implanted on a 5.5 kW, five-phase concentrated full-pitch windings induction motor. The results indicate that the proposed method can not only satisfy the requirement of a quasi-square air-gap flux, but also make the motor system good operation performance.关键词
