Description

Technical Field

[0001] The utility model belongs to the technical field of motor equipment, and in particular relates to a carbon brush holder with strong stability. Background Art

[0002] With the development of science and technology, more and more DC motors are used in various products. Among them, a middle plate component in the motor has a certain impact on the performance of the motor. One of the important parts in the middle plate component is the carbon brush holder. The carbon brush holder is an important part of rotating motors such as motors or generators. It is mainly used to fix and support carbon brushes. Carbon brushes are conductive materials that transfer current from the stationary part to the rotating part by contacting with the rotating commutator or collector ring.

[0003] Since the thickness of the carbon brush holder itself has certain requirements, stability during operation is crucial. Since the carbon brush holder is in a state of slight swing as the motor rotates rapidly during operation, this will lead to instability during operation, especially at high speeds and high power. In order to reduce this instability, the hemming design is used to provide support during the swinging process to make it more stable, reduce sparks, and ensure product performance.
