Abstract
In an electric motor, an n-th layer of windings includes: a first winding portion wound from a radially outer side of the stator to a radially inner side of the stator so as to form a gap dimensioned to one pitch or more of the windings at a preset position; and a second winding portion wound from the radially inner side of the stator to the radially outer side of the stator in a continuous manner from the first winding portion so as to fill in the gap, the second winding portion crossing the first winding portion. The gap is formed at a position that is at an intermediate portion of the tooth in a stator radial direction and that is a position at which the windings switch from the n-th layer to an (n+1)th layer.
