Abstract
A method of making an electric motor where the motor has a reduction gear and a gear cover mounted thereon. An opening is formed through the gear cover at a location corresponding to a connection portion. A pressure member is inserted into the gear cover through the opening and is pressed against another pressure member to squeeze a choke coil and a connection plate. High current may flow through the pressure members for a short time to weld the choke coil and the connection plate together by way of resistive heating.
