Claim 8:
9. An electric motor, comprising:
a stator iron core comprising:
a stator yoke in an annular form and a plurality of stator teeth extending inwards in a radial direction from an internal circumferential surface of the stator yoke; and
an end cap, the end cap being formed, in an interior thereof, with a receiving space that receives the stator iron core therein; and, a rotor that is rotatably inserted into the stator,
wherein the stator yoke has an external circumferential surface that is inwardly recessed to form at least one positioning groove, and the end cap has an internal surface provided with at least one positioning post protruding therefrom;
each of the at least one positioning post is insertable into and connectable with one of the at least one positioning groove; and
in the radial direction of the stator iron core, each of the at least one positioning groove corresponds to one of the stator teeth,
wherein the rotor casing comprises an axial stop part and a folded flange that is opposite to the axial stop part, and a protective cover is interposed and fixed between the folded flange and the rotor core.
