Analysis of Air-gap Magnetic Field Distribution and Mutual Inductance Asymmetry of Sectionally Powered Linear Induction Motor
摘要
Abstract
For segment-powered linear inductive motor, there is major asymmetry among the mutual inductance of stator windings. Based on magnetic motive force theory, this paper derived the magnetic motive force distribution of single-phase winding of the segment-powered linear inductive motor, and confirmed the characteristics of magnetic motive force distribution of the segment-powered linear inductive motor. Based on the magnetic motive force distribution of single-phase winding, the analytic expressions of air-gap field distribution of the segment-powered linear motor were derived, and the finite element simulation results verified the analytic results. Based on analysis results of motor magnetic field, the self-inductance and mutual-inductance expressions of each phase winding of motor were derived, which explained the mechanics of the mutual inductance asymmetry of segment-powered linear motor. And based on that, the obtained motor inductance matrix and resistance matrix illustrated the asymmetry laws of the motor mutual inductance and resistance. Finally the experiment results verified the correctness of the derived motor resistance matrix.关键词
