摘要

本文提出了一种新的三层磁体结构的永磁辅助同步磁阻电机(PMaSynRM)。为了确认所提出的PMaSynRM的优点,选择日产leaf 2012内饰永磁电机(IPMM)作为基准。采用有限元法对两种机器的基本电磁性能进行了研究和比较。仿真结果表明,与日产leaf 2012 IPMM相比,该设计具有更好的磁链弱化能力、更高的转矩密度和更小的转矩脉动。

Design of a Permanent Magnet Assistant Synchronous Machine with Torque Improvement
In this paper, a new permanent magnet assisted synchronous reluctance machine (PMaSynRM) with three-layer magnet arrangement is proposed for electrical vehicle applications. To confirm the merits of the presented PMaSynRM, the Nissan leaf 2012 interior permanent magnet machine (IPMM) is selected as a benchmark. The basic electromagnetic performances of the two machines are investigated and compared by finite element (FE) method. The simulations show that the proposed design exhibits a better flux weakening capability, higher torque density and lower torque ripple than Nissan leaf 2012 IPMM.
