They have high speeds, are much smaller than ordinary-power motors, are connected to the prime mover, eliminate the traditional reduction mechanism, and have a small moment of inertia. Therefore, they have the advantages of high motor power density, effective material savings, high transmission efficiency, and fast dynamic response. Existing high-speed motors do not have sound insulation and noise reduction structures, and the noise generated when the high-speed motor is working causes noise pollution. After the motor is started, the noise is too loud and vibrations are generated, causing noise pollution, and excessive vibrations can also cause certain damage to the motor.

A supporting component 6 is installed outside the through hole for connecting with the rotating shaft of the motor. A sound insulation component 7 is installed inside the cover 2 and the placement frame 1 for isolating the noise generated by the motor inside the placement frame 1. A fixing component 8 is fixedly installed on the top of the moving block 5, which is used to contact the outer wall of the motor, fix the position of the motor, and reduce the vibration of the motor when it is working; a heat dissipation component 9 is installed between the fixing component 8 and the placement frame 1, which is used to discharge the heat generated by the motor when it is working from the placement frame 1; the fixing component 8 and the heat dissipation component 9 are each provided with two groups and are symmetrically distributed on the inner side of the placement frame 1, and a driving component 10 is installed on the bottom side of the fixing plate 3, which is used to drive the two groups of fixing components 8 to move their positions.

[0028] In this embodiment, a cover 2 is provided at the top of the placement frame 1, and the motor can be placed inside the placement frame 1.

Then, the cover 2 is installed on the top of the placement frame 1 so that the cover 2 and the placement frame 1 form a sealed space.
