抑制内置式永磁同步电动机的转矩脉动是提高其效率和响应性的关键。在这里，我们报告的电磁能量采集器的发展纳入IPMSM抑制其扭矩波动。建议收割机驱动振荡的交流电机的速度涟漪。根据欧拉-拉格朗日方程，推导了电机和收割机的运动方程和电路方程。我们讨论了发电的原理，并使用MATLAB/Simulink数值仿真研究建议收割机的动态行为。我们的研究结果表明，主动科里奥利力不必要地降低了电机的原始扭矩，导致发电不成功。然而，我们的研究结果表明，反作用科里奥利力成功地抑制了电机转矩涟漪。
The suppression of torque ripples in an interior permanent magnet synchronous motor (IPMSM) is essential to improve its efficiency and responsiveness. Here, we report on the development of an electromagnetic energy harvester incorporated into an IPMSM to suppress its torque ripples. The proposed harvester is driven to oscillations by the speed ripple of the AC motor. We derived the motion and circuit equations for the motor and the harvester according to Euler-Lagrange equations. We discussed the principle of electrical power generation and used MATLAB/Simulink numerical simulations to investigate the dynamic behavior of the proposed harvester. Our findings revealed that the active Coriolis force unnecessarily reduces the motor's original torque, leading to unsuccessful power generation. Nevertheless, our results demonstrated that the reactive Coriolis force successfully suppresses the motor torque ripple.
