A carbon brush for motor

Abstract

The invention relates to the technical field of carbon brushes, and discloses a carbon brush used for motors, which includes a carbon brush placement case, a circular groove is opened at the central axis of the carbon brush placement case, and the upper and lower sides of the carbon brush placement case are Carbon brushes are respectively arranged at both ends. The carbon brush used for the motor can clean the carbon powder left on the surface of the motor by placing bristles on the inner ring of the carbon brush housing. At the same time, the carbon brush will vibrate slightly when it is working. Under the action of vibration, the carbon brush can be moved inward under the action of the compression spring, and then the deformation capsule will be squeezed. Under the action of extrusion deformation, the deformation capsule can be deformed, so as to push the arc-shaped moving rod. Under the action of the arc-shaped moving rod, the arc-shaped gas plate can drive the bristles to have a repeated horizontal rotation force on the basis of the original work, thereby improving the cleaning effect of the device on the outer surface of the motor.

Description

technical field [0001] The invention relates to the technical field of carbon brushes, in particular to a carbon brush used in motors. Background technique [0002] The function in the motor is to change the direction of the current to divide the DC motor and the AC motor. The DC motor is to change the conductive coil of the rotor, thereby changing the magnetic pole of the rotor, and then changing the movement of the motor. The carbon brush is used on the commutator or slip ring of the motor as a sliding contact body for leading and importing current. Almost all brushed motors use carbon brushes, which are an important component of brushed motors. [0003] However, the existing brushes are generally carbon brushes. Therefore, when the brushes work, the frictional rotation between the brushes and the motor will leave a part of carbon residue on the surface of the motor. If these carbon residues are not cleaned in time, the long-term Left on the motor, it is easy to affect t...

Problems solved by technology

[0003] However, the existing electric brushes are generally carbon brushes. Therefore, when the electric brushes are working, the frictional rotation between the electric brushes and the motor will cause a part of carbon residue to remain on the surface of the motor. Left on the motor, it is easy to affect the work of the motor
