Abstract

A motor including a stator assembly and a rotor assembly. The stator assembly includes a stator core and a winding; the stator core includes a yoke and a plurality of teeth protruding inwards from the yoke; between two adjacent teeth formed is a winding slot; the winding is arranged in the winding slot, and winded on the teeth. The rotor assembly includes a rotor core and a permanent magnet. The rotor core includes an annular ring having a central axial bore and a plurality of magnetic induction blocks protruding outwards from an outer side of the annular ring. Between two adjacent magnetic induction blocks formed is a radial recess for mounting the permanent magnet. The magnetic induction blocks at both sides of an opening of the radial recess protrude with a hook block. The thickness of the rotor core is larger than that of the stator core.
