[0032] Such as Figure 1~3 A built-in permanent magnet synchronous motor for karts is shown, including a stator core, a rotor core and a rotor shaft. The stator core is sleeved on the outside of the rotor core, and the rotor core is sleeved on the outside of the rotor shaft. The stator core It is made of laminated silicon steel sheets, and the rotor core is made of laminated silicon steel sheets; the rotor core includes a shaft hole in the center, and the side wall of the shaft hole is provided with a keyway matching the rotor shaft flat key. The stator core is equipped with 24 stator teeth, and stator slots are formed between adjacent stator teeth. The stator teeth and stator slots have a symmetrical structure in the radial direction. The end of the stator teeth facing the rotor is the tooth end of the stator teeth, and the stator teeth The central part of the tooth end is provided with an arched virtual groove. The rotor iron core is provided with 4 opposite V-shaped magnet...
