| Abstract |
A permanent magnet was used to improve the torque density of the magnetic gear for gear ratio conversion, and a study was conducted to attach the permanent magnet to the tooth tip of the rotor. Through this, it was found that attaching a permanent magnet to the outer rotor is effective. In addition, in the case of gear ratio conversion, in this method, there is a part where the magnetization direction of the electromagnet and the permanent magnet are opposite, resulting in poor results. Therefore, when applied to teeth with coincident magnetization directions, good results were obtained in all cases even when the gear ratio was converted. |
