Abstract

In this paper, we investigated the iron losses in the rotor core of interior permanent magnet synchronous machine (IPMSM), which have distributed armature windings. From the analysis results, we can conclude that iron losses of rotor are definitely large at load condition if the number of slots per pole is fractional. Since the slot-pole combination may induce excessive heating, particular care should be necessary in design of PMSM for a high power rating application such as electric vehicles.
