モータ駆動組立体
Document Type and Number:
Japanese Patent JP6863721
Kind Code:
B2
Abstract:
A motor driving assembly includes a motor. The motor includes an outer housing, and a rotor and a brush holder received in the outer housing. The rotor includes a rotary shaft extending out of the outer housing. A commutator is fixed on a shaft portion of the rotary shaft within the outer housing. Brushes for contacting the commutator are disposed on the brush holder. A visible identification mark fixed relative to the rotary shaft is disposed outside the outer housing of the motor, such that a relative position between the brushes and the commutator in a rotational direction of the rotary shaft is identifiable by reference to a position of the visible identification mark relative to the outer housing in the rotational direction of the rotary shaft. As such, the commutator can be prevented from stalling at a position where arcing noise may be easily generated.
