In order to study the effect of different SVPWM modulation carrier forms on the performance and loss of permanent magnet synchronous motor (PMSM), the finite element analysis model of a PMSM is established, the mathematical model of the PMSM and SVPWM control circuit are built. In the control system, two carrier forms are considered, named triangular wave and sawtooth wave. Based on the field circuit coupling method, the torque and loss at different speeds are compared. The influence of different carrier forms on motor performance is obtained. The result shows that the torque ripple of the triangular carrier motor is less than that of the sawtooth carrier in the SVPWM modulation, and the motor loss is basically the same in the two carrier forms. Finally, a prototype experimental platform is established to verify the correctness of the simulation.

SVPWM调制载波形式对永磁同步电动机性能和损耗的影响

为了研究不同SVPWM调制载波形式对永磁同步电动机（PMSM）性能和损耗的影响，建立了永磁同步电动机的有限元分析模型，建立了永磁同步电动机和SVPWM控制电路的数学模型。在控制系统中，考虑了两种载波形式，分别是三角波和锯齿波。基于现场电路耦合方法，比较了不同速度下的转矩和损耗。获得了不同载体形式对电动机性能的影响。结果表明，在SVPWM调制中，三角架电机的转矩脉动小于锯齿架，并且两种载体形式的电动机损耗基本相同。最后，建立了原型实验平台，以验证仿真的正确性。
