Research of Air-Gap Magnetic Field Distribution of Segment-Powered Linear Induction Motor

Abstract:

For segment-powered linear induction motor (LIM), 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 induction motor, and confirmed the characteristics of magnetic motive force distribution of the segment-powered linear induction 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.
