Coil structure for electric motor

摘要

Molded coil pieces inserted into a slot are separately connected to molded coil pieces belonging to another slot of the same phase as the former coil pieces by a connecting member. The connecting member has conductive members laminated in a direction perpendicular to a rotating shaft of the rotor in the motor via insulating layers, and the molded coil pieces are separately connected to each other by these conductive members, whereby the protrusion of a coil end from each slot can be reduced, which permits the miniaturization and the weight reduction of the motor. Furthermore, the dimensional accuracy of the connecting members can be improved by a simple constitution and manufacturing process, whereby the characteristics of the electric motor can be remarkably improved.
