Description

Technical Field

[0001] The utility model relates to the technical field of motor carbon powder cleaning production, in particular to a motor carbon powder cleaning device. Background Art

[0002] At present, large motors are mostly used as the main drive in the metallurgical industry, such as cold rolling mills. Although the motor has an independent air-cooled dust removal system, with the wear of the carbon brushes, too much carbon powder accumulates. After the carbon powder is adsorbed by the ordinary filter cotton, it will soon be saturated, resulting in too high carbon powder content in the air inside the motor. Under the action of high temperature and large armature current inside the motor, the commutation spark of the motor increases, which has an adverse effect on the normal operation of the motor, even leads to commutation failure of the motor, increases the maintenance time, and affects the normal operation of the production line.
