TRIPLE LAYER WINDING PATTERN, AND METHODS OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a triple layer winding structure of a three-phase four-pole motor, which achieves advantage of lap winding while contributing to automatization, and to provide a manufacturing method thereof. SOLUTION: The triple layer winding pattern in each of multiple slots of a stator of the three-phase four-pole motor is constituted of: a first wiring layer including a first phase first coil group, a first phase second coil group, a first phase third coil group and a first phase fourth coil group which are stored in a lower part of a plurality of slots and form a pair of first and second poles of the first phase; a second wiring layer including a second phase first coil group, a second phase second coil group, a second phase third coil group and a second phase fourth coil group which are stored partially in the lower part and partially in an upper part of the a plurality of slots and form a pair of first and second poles of the second phase; and a third wiring layer including a third phase first coil group, a third phase second coil group, a third phase third coil group and a third phase fourth coil group which are stored in the upper part of a plurality of the slots and form a pair of first and second poles of the third phase.
