Title:
BRUSHLESS MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/097338
Kind Code:
A1
Abstract:
A noise reduction structure of this brushless motor has: a circuit board mounted with a switching element and an electrolytic capacitor on a first surface; a conductive member facing a second surface on the opposite side to the first surface of the circuit board; a conductive connection portion for connecting a conductive pattern and the conductive member to each other, said conductive pattern being formed on the circuit board and connected to the cathode terminal of the electrolytic capacitor; and a dielectric body interposed between the circuit board and the conductive member in a state of making contact with the circuit board and the conductive member and disposed at a position where the dielectric body is electrostatically connected to the switching element.
