摘要
利用FEM对考虑磁路饱和的永磁同步电机二维磁场进行数值解析,并给出了包含正交磁化现象影响的d,q轴方程式以及转矩和电抗的计算公式。通过改变转子的位置计算永磁同步电动机的静态转矩和电抗,给出了转矩和电抗随转子位置变化规律的曲线。实验验证了理论计算的正确性。
The method for calculating torque and reactance of a permanent magnet synchronous motor considering magnetic saturation by means of FEM for two-dimensional mumerical magnetic field dq = axes equations witch include the cross- magnetizing phenomenon and formular of calculating the torque and reactance is given. The torque and reactance is calculated by changing the position of rotor and the changing curves of torque and reactance is also provided. The correctness of this algorthm is verified by experimental results.
