Abstract

The invention relates to a motor, relates to the field of motor equipment, and mainly aims at solving technical problems that a conventional motor is not sufficient in mechanical strength and has a problem of shaft current corrosion. The main technical scheme of the invention is that the motor comprises a motor case, a plastic packaging part, and a stator module with a stator core; the stator module is disposed in the motor case, and there is a gap between the stator module and the motor case; the strength of the motor case is greater than the strength of the plastic packaging part; the plastic packaging part is located in the gap, and is integrated on the stator module and the motor case. In addition, the motor case can be made of a conductive material, such as metal. The stator core makes contact with the motor case. According to the technical scheme of the invention, the strength of the motor case is greater than the strength of the plastic packaging part, thereby enabling the mechanical strength of the whole motor to be increased. In addition, because the stator core makes contact with the metal motor case and is in effective connection with a rear end cover and a rotor bearing to form an equipotential level, the motor is enabled to be grounded effectively, and the shaft current of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to a motor. Background technique [0002] The currently used plastic-encapsulated motor is to use the plastic-encapsulated compound directly as the casing, the stator core and the front end cover for integral injection molding. Although the insulation performance of this structure is good, it is used under relatively harsh conditions (such as: sunshine, rain, vibration, etc.) etc.), there is insufficient structural strength, and the plastic sealing compound is prone to cracking; and the stator core is not in direct contact with the front and rear end covers, which easily electrifies the shaft. In addition to endangering personal safety, the shaft current will also corrode the front and rear bearings. Reduce product life. The currently used plastic-encapsulated motors generally use conductive tapes, conductive wires, etc. to connect the front and rear end covers ...
