碩士 === 逢甲大學 === 電機工程所 === 97 === This paper deals with the design of an interior permanent magnet (IPM) synchronous motor for use in electric power steering system. Such an application requires the motor having small volume, high efficiency and low torque ripple. First, three IPM synchronous motor configurations are analyzed and compared. One of them is chosen based on the performance requirement. Second, to enhance the motor performance and reduce the magnet volume, the Taguchi method coupled with the finite element analysis is performed. Finally, the heat transfer analysis of the motor is also conducted. Results show that the designed fractional-slot IPM synchronous motor meets the specification within the permissible temperature rise.
