Numerical Simulation on Electromagnetic Energy Harvester Oscillated by Speed Ripple of AC Motors

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 electromagnetic energy harvester incorporated into IPMSM suppress ripples. proposed driven oscillations by speed ripple AC motor. We derived motion circuit equations for according Euler–Lagrange equations. discussed principle electrical power generation used MATLAB/Simulink numerical simulations investigate dynamic behavior harvester. Our findings revealed that active Coriolis force unnecessarily reduces motor’s original torque, leading unsuccessful generation. Nevertheless, our results demonstrated reactive successfully suppresses ripple.
