N2 - Permanent Magnet (PM) motors, among various type of motors have high energy density. This features makes PM motors favorable choice for application involving high torque and volume constraints such as electric vehicles. While running the vehicle at high speed PM motors are made to operate in a large speed range. During the operation many a times motor core gets saturated. In this paper, an analytical model for surface mounted PM motor considering the non-linear behavior of motor core has been presented. The presented model is an attempt to enable the analytical model to take into account the non-linear nature of ferromagnetic material. Material property has been included in the analytical model in a novel way while defining boundary conditions between different regions of the motor. Results for radial and tangential components of air-gap magnetic field along with relative permeability variation in stator core for no load and on load have been presented in comparison to the results obtained from finite element analysis.
