Low-noise split type motor stator structure

Abstract

The utility model discloses a low noise split type motor stator structure, which comprises a plurality of stator core blocks, the plurality of stator core blocks are spliced to form an annular iron core, each stator core block comprises a wrapping post, an arc yoke arranged at the upper end of the wrapping post and an arc pole shoe arranged at the lower end of the wrapping post, and the two ends of each arc yoke are provided with splicing structures. And the end part of each arc-shaped pole shoe is provided with a sealing edge which extends along the arc direction of the arc-shaped pole shoe and can seal a wire slot opening formed between two adjacent arc-shaped pole shoes. The stator core block is reasonable in structural design, the end parts of the arc-shaped pole shoes of the stator core block are provided with the sealing edges, and after the positioning iron core is assembled, the sealing edges can seal wire slot openings between the adjacent arc-shaped pole shoes, so that the slotting defect of a traditional split stator is effectively eliminated, a closed magnetic circuit is formed at the end parts of the arc-shaped pole shoes, air gap magnetic conductance mutation is reduced, and the service life of the stator core block is prolonged. Noise and vibration of the motor are effectively reduced; and the whole structure is simple, splicing and winding are easy, and the winding efficiency and the slot fullness rate are effectively improved.
