Electric motor, compressor including the same, and method of manufacturing electric motor

An electric motor including a stator, the stator including a core, the core including a tooth on which a winding is wound at a preset pitch to form a plurality of layers of the winding, the winding of one of the layers being angled to the winding of another one of the layers adjacent to the one of the layers,

• wherein an n-th layer of the winding comprises:
• a first winding portion wound from a radially outer side of the stator to a radially inner side of the stator with a gap between one turn and another at a preset position, the gap being dimensioned to one pitch or more of the winding;
• 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 to fill in the gap, the second winding portion crossing the first winding portion, and
• the gap is at a position at an intermediate portion of the tooth in a radial direction of the stator, the position being a position at which the winding turns over from the n-th layer to an (n+1)th layer, and
• a start end of the winding of the (n+1)th layer being in abutment with the winding wound to fill in the gap.
