Patent ID: 8330318

Claim:
A rotating electrical machine, comprising: a stator that comprises a stator core and a stator coil; and a rotor disposed rotatably on an inner circumferential side of the stator core, wherein: the stator core comprises a plurality of slots opening on the inner circumferential side and the slots are each formed as an open slot with a width of an inner circumferential-side opening thereof ranging along a circumferential direction set substantially equal to or greater than a width of a bottom side measured along the circumferential direction; the stator is formed by mounting an insulator constituted with an insulator sheet at the stator coil as an integrated part thereof and winding the stator coil through the plurality of slots; the stator coil includes a pair of coil segments of a single phase which are constituted with a single continuous conductor, wherein one of the pair of coil segments is inserted in and wound through a first slot and a second slot which is separated from the first slot by more than one slot among the plurality of slots, and wherein another of the pair of coil segments is inserted in and wound through a third slot which is adjacent to the first slot and a fourth slot which is adjacent to the second slot; a number of slots present between the first slot and the second slot is the same as a number of slots present between the third slot and the fourth slot; and the number of slots present between the first slot and the second slot is one or more and the number of slots present between the third slot and the fourth slot is one or more.
