ROTARY ELECTRIC MACHINE, CONSECUTIVELY WOUND COIL OF CRANK SHAPE, DISTRIBUTED WINDING STATOR, AND FORMING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To obtain a small and high-output rotary electric machine, by making a coil end smaller than before and by reducing current density in a distributed winding stator using rectangular conductors for coils.

SOLUTION: The distributed winding stator is formed by winding conductor strands of a rectangular shape in cross section in an overlapped state, by forming crank shapes in such a way as to displace top head portions at both ends by the total width of the strands wound in the overlapped state and to make the crank length within the range of an interval of adjacent slots, and by inserting the coils into the slots of the stator.
