Rotating electric machine stator and rotating electric machine

A stator of a rotating electric machine, the stator comprising a winding, wherein

• the winding has a plurality of divisional coils,
• each of the divisional coils has a pair of slot-inside stored portions which are respectively stored in different slots among a plurality of slots formed between adjacent teeth of the stator,
• where a number of poles of a rotor used together with the stator is P, a number of phases of an AC power supply applied to the rotating electric machine is M which is an integer not less than 3, and a number of the slots is Sn, a number q of slots per pole per phase represented as q=Sn/(P×M) is an irreducible fraction, and
• the divisional coils include two types which are a large-divisional coil of which the pair of slot-inside stored portions are each stored alone in the slot and are connected via coil end portions on both end surface sides in an axial direction of the stator, thus being wound by single-layer concentric winding, and a small-divisional coil of which the pair of slot-inside stored portions are each stored in the slot together with the slot-inside stored portion of the other corresponding divisional coil.
