Abstract:
Provided is a rotary electric machine which is configured to draw three-phase output lines from a connection side coil end by an easy process. A stator for a rotary electric machine according to the present invention includes a plurality of segment coils including connection-side winding portions and non-connection-side winding portions. The connection-side winding portions are arranged on one side of a stator core and connected to slots with the same slot pitch, and the non-connection-side winding portions are arranged on the other side of the stator core and inserted into the slots with a plurality of kinds of slot pitches. The connection-side winding portions include a first connection group and a second connection group. The first connection group is provided with a plurality of terminal portions for connecting the segments, and the second connection group connects layers different from those in the first connection group, and is provided with a plurality of terminal portions.
