ABSTRACT:
A technique of facilitating a coil winding work by continuously winding coils in the same direction, in a stator in which a plurality of coils constituting a coil group of the same phase are respectively arranged so as to include positions at which phases of induction voltage are different, whereby coil groups of three phases are disposed in a ring shape. A stator (102) of the invention has a structure in that a pair of coils (21U1, 21U4) and coils (21U2, 21U3) in which phases of induction voltage are identical in a plurality of coils (21U1to21U4) constituting a U-phase coil group (21U) are set as different divided groups, the respective coils (21U1, 21U4) and coils (21U2, 21U3) in the divided group are continuously wound in the same winding direction while arranging crossovers (26U1, 26U3) respectively between the coils (21U1, 21U4) and between the coils (21U2, 21U3), the divided groups are connected in parallel, and a V phase and a W phase are executed in the same manner, whereby lead wires of three-phase coil groups (21U,21V,21W) are star connected.
