Title:
MOTOR AND MOTOR-MOUNTED DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/012024
Kind Code:
A1
Abstract:
Provided are a motor and a motor-mounted device that are capable of reducing noise by further suppressing vibration transmission from a joined part of a stator and a case. A motor 2 is provided with: a rotor 22 that is coupled to a shaft 6; a stator 21 that surrounds the rotor 22; and a case 4 that houses the rotor 22 and the stator 21. The stator 21 is joined to the case 4 by a plurality of joined parts P distributed in the peripheral direction D1 of the stator 21. Assuming that there are multiple antinodes distributed in the peripheral direction D1 with regard to a second, third or fourth vibration mode, the positions of the joined parts P in the peripheral direction D1 are set such that, when one of the antinodes A is positioned at one of the joined parts P, no antinodes A are positioned at any joined part P simultaneously.
