Abstract: To solve the problem of energy loss caused by frequent rotor commutation during bidirectional mechanical energy generation, the mechanical motion rectification permanent magnet generator ( MR-PMG) with planetary transmission could achieve the power generation process of bidirectional mechanical energy input to unidirectional rotor output. In order to study the electromagnetic performance of the generator, simulation model of its electromagnetic structure was established, the no-load electromotive force, air gap magnetic density, and electromagnetic performance under load operation were obtained. The experimental prototype was fabricated, and the electromagnetic performance testing platform was built. The test results of electromagnetic performance was basically consistent with the simulation results, the rationality of electromagnetic structure and effectiveness of finite element simulation model were verified.
