Therefore, it has the advantages of high motor power density, effective material saving, high transmission efficiency, and fast dynamic response. Existing high-speed motors do not have a sound insulation and noise reduction structure, and the noise generated during the operation of the high-speed motor causes noise pollution; after the motor is started, the noise is too loud and vibrations will occur, causing noise pollution, and excessive vibrations will also cause certain damage to the motor.
