Abstract

The invention discloses a novel waterproof stator, which includes a hollow stator core with windings, the top of the stator core with windings is provided with an iron core hole and the bottom is provided with a connecting wire; the stator further comprises a cylindrical hollow bracket, a base is arranged at the bottom of the bracket, a wire outlet hole is arranged on the base, and a hollow positioning column is arranged in the bracket, wherein the positioning column corresponds to the iron core hole of the stator core, and the height of the positioning column is consistent with the height ofthe bracket; the stator iron core with windings is arranged in the bracket through the positioning column device, the top of the bracket is provided with a sealing cover, the sealing cover is consistent with the size of the bracket, a hole is arranged on the sealing cover, and the hole corresponds to the positioning column. The invention provides the novel waterproof stator with strong sealing property, good waterproof ability, prolonged service life and high safety strength.

Description

technical field [0001] The invention relates to the technical field of motor devices, in particular to a novel waterproof stator. Background technique [0002] The motor stator is an important component of the motor. The stator is composed of three parts: stator core, stator winding and frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to generate a tangential force along the circumferential direction in the rotating magnetic field. [0003] The stator of the motor contains iron core and coil windings. At present, when the motor is working, moisture will seep into the iron core and coil windings in the stator from the connection gap, which will cause the iron core to rust or reduce the insulating glue between the coil windings after a long time. The resistance value will affect the service life of the motor. [0004] The Chinese patent application number is 201520500619.9, the application date: July 09...
