Air processor and alternating current plastic-sealed motor and stator thereof

Abstract

The invention discloses a stator of a motor, which comprises a winding and a stator iron core with a groove, wherein the winding comprises a plurality of sub-windings distributed along the periphery of the stator; the sub-windings comprise a first phase windings and a second phase windings; the first phase windings comprise even numbers of windings; each of the windings is wound in a groove of a yoke portion of the stator iron core; the second phase windings comprise at least a groove-crossing coil; and the groove-crossing coil is wound inside the groove of the stator iron core by crossing the groove. The stator of the invention comprises the first phase windings wound on the yoke portion of the stator iron core and the second phase windings located inside the groove of the stator iron core by crossing the groove; the first phase windings are distributed on the outer circumference of the stator iron core; the outer circumference space that can be occupied is wound with large amount of vanished wires and the groove on which the second phase windings are located won't be blocked; the number of coils of the groove-crossing coil inside the groove to which the second phase windings are located are added; and the two phase windings are not interfered with each other, thus the rate of filling the groove with windings is improved and further the efficiency of the motor is improved. The invention also comprises an alternating current plastic-sealed motor and an air processor that are provided with the stator.

Description

technical field [0001] The present invention relates to the technical field of air treatment, relates to an air processor, and more specifically relates to an AC plastic-encapsulated motor of the air processor and a stator of the motor. Background technique [0002] The plastic-encapsulated motor uses plastic packaging technology to package the stator core and winding of the motor with engineering plastics as a whole, which can cancel the traditional motor stator insulation treatment process and the metal casing of ordinary motors. Therefore, it has low noise and strong corrosion resistance. , low cost and other advantages, so it is widely used in household appliances such as vacuum cleaners, range hoods, air conditioners, washing machines and instrument fans. [0003] At present, the iron core of the plastic-encapsulated motor adopts the teeth-yoke separated iron core. The winding is wound across the slots on the teeth and then pressed into the yoke of the stator core, foll...

AI Technical Summary

Problems solved by technology

In the above-mentioned winding method, since the windings are all wound across slots, adjacent parts will overlap, that is, one winding will block part of the winding slots of the other winding, resulting in a decrease in the slot fullness rate and affecting the efficiency of the motor.
