Abstract :
This paper analyzes and compares the performance of fractional-slot concentrated-windings (FSCW) and integer-slot distributed-windings for reducing torque pulsation in interior permanent magnet (IPM) machine for a hybrid electric vehicle. By analyzing the analytical expressions of cogging torque and ripple torque derived by energy method and principle of virtual displacement, several methods are proposed to reduce the torque pulsation for both of FSCW and distributed-windings. The finite element analysis (FEA) simulation software ANSOFT is used to calculate the performance of the machine including the flux-weakening capabilities of the machines with these two windings. The comparison results show that the machine with FSCW has better performance than the machine with integer-slot distributed-windings.
