An analytical model for interior permanent-magnet synchronous machine is detailed using the equivalent d-q machine based on the determination of flux density waveforms in the different axes of the d-q frame. The main parameters of the Park model machine are analytically expressed. The expressions of electromotive force, d-, and q-axis synchronous inductances are derived considering the presence of...
This paper presents a design approach to an interior permanent magnetic synchronous motor (IPMSM) for the compressor of a hybrid electric vehicle operated in a 42-V battery system. The approach is to estimate the range of inductance and back-EMF to satisfy the required efficiency of IPMSM. Then, the preliminary geometry satisfying the region is decided by PM type, current density, fill factor, and...
