Abstract
The invention discloses a device and a method capable of preventing electrolytic corrosion of a motor bearing. The device comprises a plastic package stator (1) and an end over (2) matching the plastic package stator (1). The device is characterized in that an L-shaped metal sheet (4) is connected on the outer surface of a stator core (3) of the plastic package stator (1), the short side of the L-shaped metal sheet (4) is connected with a bridging metal sheet (5) which is transversely arranged, a connecting metal sheet (6) is arranged the end part of the bridging metal sheet (5), a U-shaped metal sheet (7) is arranged at the end part of the connecting metal sheet (6), the U-shaped metal sheet (7) contacts the groove of the end cover (2). The method includes guiding potential on the surface of the stator core to the end cover successively via the L-shaped metal sheet, the bridging metal sheet, the connecting metal sheet and the U-shaped metal sheet so as to remove the potential, thereby effectively preventing electrolytic corrosion of the motor bearing. The device and the method can be used for preventing electrolytic corrosion of the motor bearing so as to ensure the service life of the bearing.
