Motor stator assembly and compressor having the same

Abstract

The invention discloses a motor stator assembly and compressor having the same. The motor stator assembly comprises a stator core, an insulating layer, a first insulated framework and a second insulated framework; the first insulated framework is arranged at one end of the stator core; the first insulated framework is provided with a first slot corresponding to the position of a stator core slot; one side of the first slot close to the outer periphery of the first insulated framework is provided with a first stopping part; a second stopping part is arranged on the first insulated framework adjacent to an opening of the first slot; one end of the insulating layer leans against the first stopping part and the second stopping part; the second insulated framework is arranged at the other end of the stator core; the second insulated framework is provided with a second slot corresponding to the position of the stator core slot; and the other end of the insulating layer leans against the second insulated framework. According to the motor stator assembly of the embodiment of the invention, movement of the insulating layer can be defined, and the space utilization in the slot can be improved and the spacer factor can be promoted.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a motor stator assembly and a compressor having the same.

[0002] For motors in the related art, the production process of the concentrated roll stator is different from that of the distributed roll stator. The concentrated roll usually adopts the form of installing an insulating frame to ensure the insulation between the iron core and the winding. A kind of plug-in insulation published in Chinese patent 201220239609.0 Although the frame has the advantages of simple operation and convenient installation, since the insulating frame is an injection-molded part, the thickness of the plug-in insulating frame is relatively large at the part inserted into the embedding slot, which will inevitably occupy a certain slot area, which is not conducive to the improvement of the performance of the motor.

However, if the plug-in type (insulating frame) is used, it will inevitably occupy the space in the winding slot (the insulating frame is an injection molded part whose thickness is usually greater than 0.5mm, while the insulating paper is usually only 0.19-0.25mm), which is not conducive to the utilization of slot fullness.

[0003] In order to improve the utilization of the slot full rate, there is now a three-stage structure, that is, the upper and lower insulating frames are combined with slotted insulating paper. Patent CN201510524388.X discloses an insulating frame, although the insulating frame of this patent is beneficial to the stator slot full utilization, but the insulating frame of the stator assembly still needs the insulating frame to be attached to the insulating paper in the slot, so the insulating frame still needs to occupy a certain space in the slot, and the improvement of the slot full rate is limited
