END TURN AND TERMINAL SUPPORTS IN DYNAMO ELECTRIC MACHINE AND MANUFACTURING METHOD THEREFOR

摘要

In a stator for use in a rotary electrical machine, such as an electric motor, and a manufacturing method for such a stator, the coil end of the stator coil is inserted in an iron core and clamped to have predetermined dimensions within shaping molds and is fixed through injection of moldable resin into the molds. A terminal structure for connections between coil winding ends and lead wires is simultaneously formed on the coil end with the same moldable resin. This terminal structure is provided, in the outer peripheral surface thereof, with a plurality of grooves for embedding therein the connections between the coil winding ends and lead wires, for efficient insulation and fixing of these connections to the terminal structure.
