Patent ID: 8779644

Claim:
A stator coil used in a rotating electrical machine, comprising: three groups of coils, wherein: coils of each of the three groups of coils are wound continuously upon divided cores with one or more crossover wires, in which 2N coils (where N is a natural number) are arranged at approximately regular intervals, wherein a winding direction of N coils, which are first through Nth continuously wound coils, of a front half of the 2N coils, and a winding direction of rear half coils which are (N+1)-th through (2N)-th continuously wound coils, are opposite; and neutral points of the three groups of coils are connected by connecting together central crossover wires at central portions of the three groups of coils with a connection terminal, the central crossover wires each extending from a winding end of an Nth coil to a winding start of a (N+1)-th coil in each of the three groups of coils and being connected together with the connection terminal at a region where the central crossover wires overlap each other in the three groups of coils being assembled together.
