Abstract :
This paper compares the distributed winding and concentrated winding IPMSMs designed for direct-drive wind turbine. Apart from different stator winding configuration, the two IPMSMs have identical rotor and stator dimensions, air gap length, magnet length and stack length. The paper also discusses various techniques that were applied to minimize the cogging torque and torque ripple.
