Patent ID: 8736132

Claim:
A stator of a rotating electrical machine comprising: a stator core with an annular shape having a plurality of slots in a circumferential direction; and a stator winding formed by winding a plurality of lead wire around the stator core; wherein, the lead wire has a slot accommodation part accommodated in the slot and a turn part that mutually connects the slot accommodation parts that are accommodated in the different slot in a circumferential direction outside of the slot; and bent parts are formed to two positions of the turn part and the turn part is formed in non-symmetric shape in the circumferential direction; wherein: the turn part comprises: a projection part that projects from a first slot in a direction parallel to an axial direction of the stator core; a slope part bent in a circumferential direction from a tip of the projection part and diagonally extended at an angle of less than 90 degrees aiming to a Kth slot (K is a natural number) that is separated from the first slot at a specific interval; the stator winding has m phases (m is a natural number), has a number of slots n (n is a natural number) per phase and per pole, and has 2p magnetic poles; a total number of the slots in the stator core is m×n×2p (p is a natural number) and the k is m×n+1; the lead wire is a continuous line that winds around once around the stator core by repeating the projection part and the slope part 2p times at the interval of the first slot and Kth slot; and when the lead wire winds around the stator core by J turns (J is a natural number), at least two slot accommodation parts of the 2p slot accommodation parts in the same turn have the same radial distance from an axial center of the stator core.
