ABSTRACT:
A stator coil used in an electric motor, including a bobbin formed by insulating material and composed of a hollow cylindrical portion and two end plates provided projectingly toward the outside in the radial direction from the cylindrical portion at both ends in the axial direction thereof, at least two connector plates made of conductive material of which one end is inserted into an outer periphery of one end plate of the bobbin and of which the other end is extended outside in the radial direction of the end plate, and an exciting coil wound on the cylindrical portion. One terminal portion of a covered wire which constitutes the exciting coil is conductively connected to the one connector plate, and the other terminal portion is conductively connected to the other connector plate. The connector plates are insulatingly held in a housing of the electric motor and their free ends are provided projectingly outside the outer surface of the housing, thereby forming a connector.
