Description

Technical Field

[0001] The utility model relates to the technical field of carbon brush brackets, in particular to a suspended carbon brush bracket. Background Art

[0002] The role of carbon brushes in motors is to change the direction of current. Motor carbon brushes are widely used in various AC and DC generators, synchronous motors, battery DC motors, crane motor collector rings and various types of welding machines, etc. They have good commutation performance. Carbon brushes are installed using carbon brush holders. The carbon brush holder presses the carbon brushes onto the slip ring of the motor rotor through the tension of the spring, thereby maintaining stable contact between the carbon brushes and the slip ring. When the motor is running, the rotor drives the slip ring to rotate, and the carbon brushes always maintain contact with the slip ring through the tension of the spring, thereby transmitting current.
