Description

Technical Field

[0001] The utility model belongs to the technical field of direct current equipment, and in particular relates to a carbon brush middle plate component with high stability. Background Art

[0002] Carbon brush middle plate usually refers to the component used to support and fix carbon brushes in motors, generators and other equipment. Its main function is to ensure that the carbon brushes maintain a stable contact pressure with the commutator or slip ring of the rotor, and to make appropriate adjustments as the carbon brushes wear, so as to ensure that the current can be effectively and stably transmitted from the stator to the rotor, and realize the energy conversion and rotation direction control of the motor.

[0003] Since there are certain requirements for the thickness of the brush arm in the middle plate assembly, the brush arm will be in an open state when the motor is working. When the motor continues to run, the brush arm will cause heat due to the action of the current. At this time, the brush arm will be in a weak state and loose, resulting in unstable motor performance. Over time, the motor may fail. Utility Model Content
