Document Type and Number:
WIPO Patent Application WO/2020/045641
Kind Code:
A1
Abstract:
The motor according to the present disclosure is provided with a stator, a rotor, a cylindrical housing, and two neutralizers having the same predetermined natural frequency. One of the two neutralizers is disposed at a position shifted by 90º with respect to the other in the circumferential direction of the housing. Vibration having a predetermined frequency occurs in the motor in response to the rotation of the rotor, and a system from a vibration source of the motor to the joint between the motor and a device has a transfer function having a characteristic for suppressing the vibration of the joint at a predetermined natural frequency.
