Permanent magnet synchronous motor stator

The utility model discloses a permanent magnet synchronous motor stator, which comprises a positioning sleeve, a stator main body and a compression ring, the stator main body is formed by splicing a plurality of core blocks, two sides of each core block are respectively provided with a first clamping groove and a first clamping strip, the adjacent core blocks are in interference connection through the matching of the first clamping grooves and the first clamping strips, and the positioning sleeve is provided with a second clamping strip. A second clamping groove is formed in the outer end face of the core block, and the chip and the positioning sleeve are in interference fit through the second clamping strip and the second clamping groove. Through the spliced stator structure, each iron core of the stator can be independently wound and then spliced and assembled, so that the production efficiency of the stator is greatly improved, the production difficulty is reduced, the first clamping strip, the first clamp
