8. A noise-reducing high-voltage electric machine according to claim 1, characterized in that: the structure shape of the wheel disc (33) is oval, and the half of the difference between the long axis and the short axis of the wheel disc (33) is larger than the depth of the clamping groove (39).
9. The noise reduction method of the noise reduction type high-voltage motor according to claim 1, comprising the steps of:
s1: noise generated when the motor body (1) works and runs is isolated and absorbed by arranging the soundproof cotton (7);
s2: a vacuum area is enclosed between the shell (10) and the middle shell (8), so that noise cannot be transmitted in the vacuum area;
s3: the first spring (9) is used for damping and reducing noise of the motor body (1) which vibrates during working.
