Stator insulation protection holder for single-phase asynchronous plastic packaging motor

Abstract

The invention relates to a stator insulated protective support of single-phase asynchronous plastic-sealed motor. Wherein, the plastic-sealed motor comprises stator, rotor, end covers at two ends of rotation axle, absorber and insulated material; the stator is formed by stator iron core, copper coil coiling the iron core, and two semi-round insulated protective supports between the iron core and copper coil that connected by connecting parts; the insulated protective support has round circumference, whose inner side has several insulated protective support protrusions relative to the iron core; two insulated protective support protrusions have ladder groove between; the connecting part is the concave-convex structure protruded on the circumference of insulated protective support at the combine surface of said two semi-round insulated protective supports. Via said concave-convex structure, the combine part is compact. The invention can avoid wire broken or short circuit, to improve the producing efficiency.

Description

technical field [0001] The invention belongs to the field of single-phase asynchronous AC motors, in particular to a stator insulation protection frame of a single-phase asynchronous plastic-sealed motor which plays an insulating role between the stator iron core and the copper wire package of the plastic-sealed motor. Background technique [0002] At present, the fan of the indoor unit of the air conditioner uses a single-phase asynchronous motor to drive the fan to rotate. The single-phase asynchronous plastic-sealed motor has the advantages of low noise and stable operation, which can greatly reduce the noise of the indoor unit of the air conditioner. [0003] Fig. 1 is a schematic exploded view of the structure of a single-phase asynchronous plastic-encapsulated motor in the prior art. The following description will be made with reference to Fig. 1 , Fig. 2 , Fig. 3 , Fig. 4 and Fig. 5 . [0004] The plastic-encapsulated motor includes: a stator 1 fixed on the frame; a r...

Problems solved by technology

There is a certain gap between the inclined plates of this structure. During the winding process of production, it is easy for the copper wire to wind into the gap between the inclined plates of the insulation protection frame outside the iron core, so that the copper wire is cut and damaged, resulting in copper The wire is in contact with the stator core, causing the stator to be disconnected or short-circuited

Therefore, it needs to be reworked and repaired or lead to waste products, resulting in waste, reducing production efficiency, and even affecting the performance of the entire plastic-sealed motor and air conditioner
