摘要
设计了一款混合动力汽车集成式起动发电机(ISG),用钕铁硼和铁氧体混合永磁的永磁同步电机(PMSM)。分析了两种永磁体的结构参数对电机磁路的影响规律,推导了钕铁硼和铁氧体并联磁路的约束条件;以铁氧体的不可逆退磁量和电机的基本性能为优化目标,通过场-路结合的方法,确定了钕铁硼和铁氧体的结构参数;并与传统的钕铁硼PMSM在电机性能和永磁体成本等方面进行了比较分析。研究结果表明,所提出的ISG混合永磁电机能有效地减少永磁体材料成本和铁氧体退磁风险,电机性能达到了设计要求。
A permanent magnet synchronous motor(PMSM) with NdFeB and ferrite hybrid permanent magnets for hybrid electric vehicle integrated starter generator(ISG) was designed. The influence of the structure parameters of the two permanent magnets on the magnetic circuit of the motor was analyzed, and the constraints of the parallel magnetic circuit of NdFeB and ferrite were deduced. With the irreversible demagnetization of ferrite and the basic performance of the motor as the optimization objective, the structure parameters of NdFeB and ferrite were determined by field-circuit combining method. The NdFeB PMSM was compared and analyzed in terms of motor performance and permanent magnet cost. The results showed that the ISG hybrid permanent magnet motor proposed could effectively reduce the cost of permanent magnet materials and the risk of ferrite demagnetization, and the performance of the motor met the design requirements.
