Design and analysis of slot-pole combination for synchronous reluctance machine with concentrated windings for automotive applications

Synchronous Reluctance Machines (SyncRM), began to draw a lot of attention in last decade and presently receives a great deal of interest, since the cost of active materials is much lower than for a Permanent Magnet Synchronous Machine. For automotive applications a high torque and power density, low torque ripple and a wide speed range is required. The synchronous reluctance machine is still under development and intensive investigation is being carried out. This paper presents the influence of stator and rotor pole number combinations with a stator configuration which for cost reduction purposes uses only concentrate windings.
