摘要:
提出了一种永磁同步电机特性的计算方法,并以2004 Toyota Prius 驱动电机系统永磁同步电机为例,通过有限元方法计算静态气隙磁场、对比空载状态和负载状态气隙磁场的分布情况,确认负载状态时气隙磁场由定子电流主导,据此进行特性仿真。根据定子和转子的相对位置影响电机输出转矩的特点,采用瞬态场计算一个周期的堵转转矩曲线和电磁转矩曲线,通过后处理得到电机的时空矢量图和其它参数。结果表明,采用该方法能大大提高永磁电机特性和参数的计算精度。
Abstract:
It presents a calculation method of PMSM characteristics. As a sample of PMSM for the 2004 Toyota Prius motor drive system, FEA method is used to calculate static air-gap magnetic field of the PMSM. It compares air-gap magnetic field distribution in the state without load and with load, confirms the fact that load air-gap magnetic field is dominated by stator current, and then simulate the characteristics of PMSM. According to that relative position of stator and rotor will affect output torque of motor, locked torque curve and electromagnetic torque curve in one cycle can be calculated by the FEA transient field method. After post-processing, we can draw a space-time vector graph of motor and can get other parameters. Simulation results show that this method can largely improve the calculation precision of characteristic & parameter of PMSM.
