Abstract

The invention relates to the field of motor, and discloses a motor and an electrical conduction device for the motor. The electrical conduction device can be arranged between an end cover (21) and a shaft (22) of a motor (20) to electrically connect the end cover (21) and the shaft (22). The electrical conduction device includes a fixing piece (10) used for being connected with the end cover (21), and a contact piece (12) used for electrically contacting the shaft (22). The contact piece (12) is fixedly connected to the fixing piece (10) through a connecting piece (11), and can be pressed on the shaft (22). The electrical conduction device of the invention can electrically connect the inner and outer rings of motor bearings to eliminate the potential difference between the inner and outer rings of the bearings. Therefore, the problem that the bearings are damaged due to electric erosion is solved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor and an electrical conduction device for the motor. Background technique [0002] The bearing is an important part that cooperates with the rotating shaft in the motor. However, during the frequency conversion operation of the motor, the inner ring and outer ring of the bearing installed on the rotating shaft cannot be fully conducted due to the influence of the oil film inside the bearing, so that a potential difference is formed between the inner ring and the outer ring, making the balls in the bearing Discharge occurs between the inner and outer rings of the bearing, resulting in electrical corrosion of the inner and outer rings of the bearing and the balls, resulting in damage to the bearing. [0003] Therefore, it is necessary to propose a device capable of electrically conducting the inner ring and the outer ring of the bearing, so as to eliminate the potential difference betw...
