Document Type and Number:
WIPO Patent Application WO/2020/054552
Kind Code:
A1
Abstract:
A motor according to the present invention is provided with: a stator; a rotor; a cylindrical housing; and a neutralizer array that has a prescribed specific vibration frequency. The neutralizer array has at least one neutralizer group that includes a plurality of neutralizers arranged in the rotational axis direction. The motor generates vibration of a prescribed frequency in response to rotation of the rotor. A system from the vibration source of the motor to a connection part between the motor and a device has a transmission function which has properties of suppressing vibration of the connection part at the prescribed specific vibration frequency.
