AI Technical Summary
In motors with very low current and low speed, the electrical spark between the commutator segments and carbon brushes is insufficient to remove carbon dust, leading to carbon dust accumulation and affecting the normal operation of the motor.
By setting a five-degree offset between the commutator segments and the core lamination axis, the electrical spark is enhanced. Combined with the design of magnets and limit rings, the core rotation is ensured to remove carbon dust.
It effectively removes carbon dust between commutator segments, ensuring normal operation of the motor at low speeds.
