摘要： A stator assembly, having a stator formed by a plurality of pole pieces by means of injection overmolding, a columnar connection portion protruding outward being provided on an edge of one of the pole pieces; a mounting groove located at a side face of the stator; a coil wound around the stator; a pin connector with a ground pin, the pin connector being press-fitted onto the mounting groove in the direction perpendicular to the axial direction of the stator; and a magnetically conductive ring, the stator, which is mounted with the coil and the pin connector, being pressed into the magnetically conductive ring. The stator assembly has the features of having few parts and being convenient to assemble.
