This paper propose an improved semi-analytical model based on subdomain method for the performance analysis of an interior permanent magnet synchronous machine. In particular, the pole-piece and the bridge region of the rotor were modeled with finite permeability. This enables the calculation of magnetic field in the core region to account for the saturation effect, and improves the accuracy of the motor electromagnetic performance calculation
