ABSTRACT:
A stator assembly is associated with a rotor to form an alternator. The stator assembly has pole legs with pole faces, past which magnets on the rotor rotate. At least one coil bobbin with a coil thereon is slidably received over at least one of the pole legs, said at least one pole leg having a notch in a side thereof. A bobbin locking clip is positioned in a gap between a central aperture wall of the bobbin and the one side of the pole leg having the notch. The clip of springy material has two springy tabs for engagement in the notch and an embossment on a main body surface thereof, so as to provide three-point contact. The bobbin and coil to be wound thereon can be manufactured separate from the stator assembly, and then the bobbin with the coil can be slid on the pole legs after assembly. The stator is also assembled such that rivets are provided at a central portion, and rivets are provided near end faces of pole legs on which bobbins are not provided.
