PROJECT TITLE :
Analytical Model for Permanent Magnet Motor With Slotting Effect, Armature Reaction, and Ferromagnetic Material Property
Among various sorts of motors, permanent magnet (PM) motors, thanks to their high energy density, are mainly used for electric-primarily based propulsion systems. In this paper, an improved analytical model for PM motor has been presented. The model considers necessary factors, such as armature reaction, slotting effect, and influence of non-linear material property on motor’s behavior. Moreover, the main contributions of this paper are the illustration of stator windings with exact winding width using Fourier series and also the thought of effects of non-linear ferromagnetic material property. Using this model, it is possible to work out air-gap magnetic field, flux linkage, back electromotive force, cogging torque, and electromagnetic torque with high accuracy. Results from the proposed model are compared with other analytical model and conjointly with those from a finite-part analysis (FEA). The results obtained from the proposed technique match closely with the FEA.
