Title: WINDING STRUCTURE FOR ROTARY ELECTRIC MACHINE STATOR
Abstract:
In order to provide a winding structure that is for a rotary electric machine stator and that limits the height of coil ends, the present invention is configured such that: first two-loop continuous coils CA1-CA4 and second two-loop continuous coils CB1-CB4 are staggered at six slot pitches with respect to the rotational direction; output points a7, a5, a3 that are for outer-circumferential-side first two-loop continuous coils CA and that are adjacent in radial direction RCA and input points a6, a4, a2 that are for inner-circumferential-side first two-loop continuous coils CA and that are adjacent in said direction are respectively and sequentially connected; output points b7, b5, b3 that are for outer-circumferential-side second two-loop continuous coils CB and that are adjacent in radial direction RCB and input points b6, b4, b2 that are for inner-circumferential-side second two-loop continuous coils CB and that are adjacent in said direction are respectively and sequentially connected; an output point a1 for the innermost first two-loop continuous coil CA1 and an output point b1 for the innermost second two-loop continuous coil CB1 are connected; an input point a8 for the outermost first two-loop continuous coil CA4 is a current input point for a one-phase coil; and an input point b8 for the outermost second two-loop continuous coil CB4 is a current output point for the one-phase coil.
