A compact electric motor has a rotor, and a stator ( 10 ) having a slotted lamination stack ( 16 ) defining slots separated by teeth, the teeth having tooth heads ( 153 ). Partial windings ( 17 ) are arranged on the teeth. On at least one axial end of said lamination stack, jumper rings ( 11, 12, 13 ) and a neutral ring ( 14 ) are arranged. The neutral ring has a plurality of inwardly extending radial projections ( 141 ) having free ends ( 142 ) adapted for connection to ends ( 171 ) of the partial windings ( 17 ). Connection of partial windings ( 17 ) in parallel provides a favorable power/size ratio and substantial power output, even with low operating voltage.
