ABSTRACT:
The present invention has an object of providing a rational connection configuration for an inner rotor type stator comprising coil windings provided for each pole blade. Accordingly, the connection configuration of the invention comprises three types of electric conductors corresponding to U-, V- and W-phases, respectively, and shaped like a ring. Each electric conductor has a projection extended in four directions corresponding to four groups of coil windings each of a same phase, and a lead representing each phase and extending outward of an outer diameter of the stator. The electric conductors and a common electric conductor are arranged on an end plate concentrically. Connections between the coil windings and the projections respectively of the same phase are radially arranged at places outward of the grooves of the end plate as to effect connection therebetween.
