Abstract
Abstract The present invention is a stator terminal construction for use in a rotary electrical machine such as an electric motor. The coil element of the stator coil is inserted in an iron core and a coil end of the coil element extends outwardly from a corresponding end of the core. This coil end has coil winding ends extending out of it and connected to lead wires for an external power source. The terminal structure is constituted by a block of moldable resin positioned directly on the coil end having the connections between the coil winding ends and the lead wires embedded therein. The terminal structure thus serves to insulate and fix the connections between the coil winding ends and the lead wires.
