Document Type and Number:
Japanese Patent JP2018198475
Kind Code:
A
Abstract:
To reduce electric noise.SOLUTION: A power feeding device 20 for a motor comprises: a pair of three-terminal capacitors 40 and 42; a pair of brushes 32 and 34 sliding with a commutator integrally rotating with a rotor of a motor main body; and a positive side terminal 36 and a negative side terminal 38 connected with an external power supply. The positive side terminal 36 and one brush 32 are connected with each other via a first conductive part of one three-terminal capacitor 40, and the negative side terminal 38 and the other brush 34 are connected with each other via a first conductive part of the other three-terminal capacitor 42. In addition, at a second conductive part side from the ground, a third conductive part of one three-terminal capacitor 40 and a third conductive part of the other three-terminal capacitor 42 are electrically connected with each other.SELECTED DRAWING: Figure 8
