Abstract:
The coil ends in a rotating electric machine are to be made smaller in size. A stator coil 60 inserted into a slot 420 in a stator of a rotating electric machine is formed with segment coils 28 connected to one another. In the stator coil 60, the segment coils 28 each include an insulating coated portion coated with an insulating coating, and a slit 900 or a recess is formed in the insulating coated portion of each of the segment coils 28 at a coil end 140. The slit 900 or the recess is preferably formed between a diagonal conductor portion 28D and a conductor-end straight portion 28E of each segment coil 28.
