Non-Linear Analytical Model for a Multi-V-Shape IPM with Concentrated Winding

Abstract : This paper presents a non-linear analytical model of a multi-V-shape Interior Permanent Magnet (IPM) motor with non-overlapping concentrated winding. The model relies on Ampere's theorem and the flux conservation law in order to compute the flux density in the different parts of the motor. This article proposes a saturated analytical model of the stator and the rotor. The analytical model is used to calculate the average torque, the power factor and the voltage of the motor. It is 5 times faster than the 2D Finite Element Analysis (FEA). The results are compared to 2D FEA simulations and experimentally validated using a prototype motor.
