[0003] The new energy vehicle motors currently on the market have the following problems when in use:
[0004] 1. In the actual use of traditional low-noise motors for new energy vehicles, since the motors are mostly connected by the output shaft when running, and the output shaft drives the device to rotate, and when the motors rotate at high speed, noise will be generated, the noise reduction effect of traditional motors for new energy vehicles is not very good, so the noise generated during operation is difficult to be eliminated or isolated;
[0005] 2. When most low-noise motors in new energy vehicles are in use, in order to reduce the noise, they will be filled with sound insulation cotton to absorb the noise generated when the motor is running. However, the material of the sound insulation cotton itself is relatively soft, so it is more difficult to fill a whole piece. It is easy to bend or accumulate during the filling process, and it cannot be filled conveniently and evenly, which may reduce the sound insulation effect. Summary of the invention
