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 can limit the height of coil ends, the present invention is configured such that: first two-loop continuous coils CA1-CA4 and first two-loop continuous coils CB1-CB4 are staggered at six slot pitches with respect to the rotational direction; output points a7, a5, a3 and input points a6, a4, a2 are respectively and sequentially connected; output points b8, b6, b4 and input points b5, b3, b1 are respectively and sequentially connected; an innermost output point a1 is a neutral point N1; an innermost input point b2 is a neutral point N2; an outermost input point a8 is a current input point U1in for a one-phase coil that is connected in parallel; and an outermost output point b7 is a current input point U2in for a one-phase coil. Neutral point N1 and neutral point N2, which are for respective phases, are each connected to a segment conductor that has a slot insertion part and are staggered by one layer in the radial direction.
