Abstract

A stator for a rotating electrical machine, wherein when the number of slots per pole per phase, which is a value obtained by dividing the number of the slots by the number of magnetic poles of a rotor and the number of phases of alternating current generated in a stator coil, is 2, and when P denotes a magnetic pole pitch, which is a value obtained by dividing the number of the slots by the number of the magnetic poles of the rotor, and k denotes the difference between a slot pitch, which is the pitch of the slots on a side where segment coils are inserted, and the magnetic pole pitch, one of the slot pitches in an outermost layer or an innermost layer of a stator core on the insertion side is set to P + 1 and the other is set to P - 1, and one of the slot pitch in a middle layer between the outermost layer and the innermost layer of the stator core on the insertion side or the pitch of the slots on a side where joint end portions joined to each other project is set to P + k and the other is set to P - k.
