A stator assembly adapted for use in an electric motor. The assembly includes a stator core having an annular rim and a plurality of teeth extending radially inward from the rim. The stator core has an outer diameter, a root tooth diameter and an inner diameter. Each tooth has a root, a neck extending inward from the root, a head opposite the root, and a length measured from its root to its head. The neck has a width. Each adjacent pair of teeth define a slot having an area. The assembly also includes a winding having aluminum and/or copper wrapped around at least three teeth of the stator core. The stator core and winding have four, six or eight magnetic dipoles. The stator core outer diameter is in a range from about 5.1 inches to about 5.9 inches. The stator core inner diameter is less than about 3.0 inches.
