At least one tooth 204 may include an inner radial end 220, an outer radial end 222, a first side 224, and a second side 226. Moreover, the tooth 204 may include a longitudinal end 205 that is cooperatively defined by the inner radial end 220, the outer radial end 222, the first side 224, and the second side 226. (Although hidden in FIG. 2, the tooth 204 may further include another longitudinal end that is opposite the end 205 that is shown.) The tooth 204 may also include a first flange 228 at the transition between the inner radial end 220 and the first side 224. Likewise, the tooth 204 may include a second flange 230 at the transition between the inner radial end 220 and the second side 226. The inner radial end 220 may be concavely contoured between the first flange 228 and the second flange 230. Additionally, the tooth 204 may include a third flange 232 at the transition between the outer radial end 222 and the first side 224. Likewise, the tooth 204 may include a fourth flange 234 at the transition between the outer radial end 222 and the second side 226. Furthermore, the first side 224 of the tooth 204 may include a first notch 236 that defines a first step 238, and the second side 226 of the tooth 204 may include a second notch 239 that defines a second step 240. The cross-sectional profile (taken perpendicular to the axis 105) may be substantially constant along the longitudinal length of the tooth 204. Also, in some embodiments, each of the teeth 204 of the stator assembly 108 may be substantially identical.
