Title:
MOTOR WITH BRUSH AND ELECTRICAL PRODUCT
Document Type and Number:
Japanese Patent JP2022159167
Kind Code:
A
Abstract:
To provide a motor with a brush and an electric product that are capable of suppressing damage to the brush due to collision between a pin of a commutator and the brush.SOLUTION: A motor with a brush includes a shaft 10, an armature 20 provided around a shaft, a commutator 30 located on one side of the armature in an axial direction, a brush card 40 located on one side of the commutator 30 in the axial direction, and a housing 50. A protruding portion 41 is provided at a position facing the commutator 30 on the surface of the brush card 40 facing the commutator 30. The commutator 30 has a main body portion 31 provided around the shaft 10, and a pin 32 which is bent radially outward and to one side in an axial direction from an end part on the other side in the axial direction of the body portion 31. A distance between the pin 32 and the brush 42 arranged on the brush card 40 is greater than a distance between the main body portion 31 and a convex portion 41.SELECTED DRAWING: Figure 2
