| Summary: | 碩士 === 國立臺灣大學 === 機械工程學研究所 === 106 === In this paper, the magnet-assisted synchronous reluctance motor magnet reduction is used as the research topics. A finite element software is used to design a 48-slot 8-pole Integral-slot distribution winding motor to maintain the same target specifications, including maximum torque, maximum power, rated point efficiency and torque density, as a research limitation of magnet reduction. The method of reducing magnet is to change the flux barrier shape and core width of the magnet-assisted synchronous reluctance motor, increase the q-axis inductance and reduce the d-axis inductance, thereby increasing the reluctance torque content in the overall torque, and the overall torque is increased to exceed the torque design target. After the target, the space for reducing the magnet torque content is given, and the amount of the magnet is reduced to achieve the effect of magnet reduction.
Firstly, the permanent magnet synchronous motor is used as the original motor design, and the magnet amount of the original motor is used as a comparison benchmark. Then the parameters of the magnet-assisted synchronous reluctance motor are discussed, and an optimized software is combined to establish an optimized set. The process is optimized for the width of the flux barrier, the length of the flux barrier, the width of the core, the size of the magnet, and the angle of the flux barrier. Under the constraint conditions, the best parameter matching is obtained, and the purpose of the magnet reduction is achieved.
