Research of Mathematical Model of the Twelve-Phase Linear Induction Motor with Double-Sided Long Stators

Abstract

Based on the requirement of high-power linear propulsion system, a novel twelve-phase linear induction motor (LIM) with double-sided long stators was designed, and the winding construction of twelve-phase LIM was presented in this paper. On the basis of this, the mathematical model of ABC coordinates for this novel motor was derived, and the rule of the asymmetry of end-winding leakage inductance of the twelve-phase LIM with double-sided long stators, which is determined by the relative space position of the each phase end-winding in the motor, and then this rule was compared with the law of the asymmetry of end-winding leakage inductance of the multi-phase rotating motor. Simulation model of the motor was established, and the electromagnetic properties of the motor is calculated.

A new windings design for improving single-phase induction motor performance

“…Several studies have been conducted to improve the performance of asynchronous motors by increasing the number of motor windings phases [45]- [58] so that these motors can work with better performance. Therefore, research is also needed to develop the number of single-phase asynchronous motor windings to more than two windings in order for this motor to function with better performance.…”
