Abstract: A motor stator having stator windings as polyphase windings wound onto a stator core. The winding is continuously wound in a wave shape with 2N winding layers, S winding phases, and 2P poles of each phase winding. 4×S×P slots are formed in the core. Each pole of each phase has two conducting wire groups, each group has two conducting wires wound in parallel in adjacent slots, and the pitch of each conducting wire group is a normal pitch of y, a jumper pitch of y+1, and a dislocation pitch. The jumper pitch has a first pitch of y?1 and a second pitch of y+1. The dislocation pitch has a third pitch of y and a fourth pitch of y+2. One jumper pitch is used for each conducting wire group at every P?1 non-jumper pitch. One dislocation pitch is used for each conducting wire group between at least two adjacent layers.

Abstract: A stator including a stator core and a winding. A wire of the winding is continuously wound in a wave shape in the circumferential direction, a number of wound layers is 2N, a number of phases is S, a number of poles of each phase winding is 2P. The stator core is formed with 4×S×P slots; the winding per phase per pole includes two wire groups; each wire group has two wires wound in parallel in adjacent slots; the pitches of the wire groups during winding include a normal pitch and a jumper pitch; the normal pitch has alternate first and second pitches; the jumper pitch includes a third pitch and a fourth pitch; each wire group uses one jumper pitch after every P?1 normal pitches in a same layer; and the jumper pitch causes the two wires in a same wire group to be transposed in the circumferential winding direction.
