Title:
MOTOR AND ELECTRIC DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2015/001782
Kind Code:
A1
Abstract:
A motor according to the present invention comprises: a stator including a stator core with a winding wound therearound; a rotor including a rotating body circumferentially holding a permanent magnet facing the stator, and a shaft passing through the center of the rotating body and fastened to the rotating body; two bearings for supporting the shaft; and two conductive brackets electrically insulated from each other and respectively securing the bearings thereto. In the motor, the electrostatic capacitance (A) between the stator core and one bracket and the electrostatic capacitance (B) between the stator core and the other bracket are set approximately equal or equal to each other. Further, the motor has the following relationship between the electrostatic capacitance (A) and the electrostatic capacitance (B): 0.4A ≤ B ≤ 2.5A
