Nowadays, developing electric motorization for land vehicles is essential due to the crucial need to save energy. Regarding the specific speed-torque characteristics (high saturation level, high speed, considerable flux weakening) and manufacturing cost, the Interior Permanent Magnet (IPM) Synchronous Machine (SM) provides considerable advantages. This paper presents the development of a tool used for optimal acoustic and electromechanical modeling of an IPM-SM, whose highly accurate calculations and speed of resolution make it stand out from standard analytical and Finite Element models. By coupling an analytical model with static Finite Element Analysis (FEA), our ‘hybrid’ model calculates a complex global air-gap permeance per area unit, to take into account magnetic wedge permeability, stator slots shape, pre-slot height, permanent magnets (PMs) dimensions, and rotor yoke shape. An unparalleled level of precision and time of resolution are obtained for the computation of air-gap magnetic pressures.
