Abstract :
In recent years, interior permanent magnet synchronous motor (IPMSM) with concentrated windings has been interested as a smaller and higher-efficient motor than that with distributed windings. In this paper we have been analyzed the load characteristics of the eighteen IPMSM models with the various pole-slot combinations and the pole-arc angles using finite element method. The analyzed characteristics of the developed torques, that is, the magnet and of the reluctance torques, and of the torque ripple are shown and we discuss on these performance differences by the pole-slot combinations.
