Abstract: A motor includes a stator having a stator core, a first frame and a second frame, which are arranged on two axial sides of the stator core, a coupling member, which couples the first and second frames at a radially outer side of the stator while applying a holding load to the first and second frames in the axial direction, and a rotor, which is arranged at a radially inner side of the stator. The stator core includes a held portion that projects toward a radially outer side from a main circumferential portion of the stator core. The first and second frames hold, in between, at least the held portion of the stator core in the axial direction.

Abstract: In a rotor mechanism of a rotating electrical machine, a crimp groove is formed, in a circumferential direction, in an outer circumferential portion of any one of the end plates of a rotor shaft on an outside in the axial direction. The one end plate is located in the axial direction by an inside end of a crimp retainer in the axial direction that is ring-shaped, that covers the crimp groove of the rotor shaft to fit to the rotor shaft, that is fitted into the crimp groove of the rotor shaft by crimping an outside portion in the axial direction from an outer circumferential side and that engages with a wall surface of the crimp groove on the outside in the axial direction.

Abstract: A generator is provided comprising: a frame; a stator core comprising laminations; and clamping structure to axially clamp the laminations together. The clamping structure may comprise: a plurality of first finger plates engaging a first end of the stator core; a first spacer plate associated with the first finger plates and including a plurality of spaced apart first recesses; a plurality of first engagement structures, each comprising a bolt and a corresponding slidable bushing; a first spring ring in engagement with the first engagement structures; and first load-applying structure coupled to the frame to imparts a load to the first spring ring.

Abstract: An electric machine system includes a rotor core, a stator core disposed about the rotor core, an electric machine housing coupled to the stator core, a holding-cylinder disposed between the electric machine housing and the stator core, a first flange coupled to the electric machine housing at a first end of the holding-cylinder and a second flange coupled to the electric machine housing at an opposite end of the holding-cylinder.

Abstract: A stator includes a hollow cylindrical stator core comprised of a plurality of stator core segments, a stator coil mounted on the stator core, and an outer cylinder that is fitted on die radially outer surfaces of the stator core segments so as to fasten the stator core segments together. The stator core has a recess formed in the radially outer surface of one of the stator core segments. The outer cylinder has a slit that radially penetrates the outer cylinder to connect the radially outer and inner surfaces of the outer cylinder and an engaging portion that adjoins the slit. The engaging portion of the outer cylinder is plastically deformed radially inward into the recess of the stator core so as to abut and thereby engage with side walls of the recess which face the engaging portion.

Abstract: The invention relates to an electric motor having a stator and a rotor in a housing, wherein the stator comprises a plurality of lamellae that are disposed in parallel and are combined into a package. The lamellae are held together via a spring clamp, which overlaps the lamella package in an axial manner, wherein the spring clamp simultaneously supports the lamella package radially on the interior wall of the housing.

Abstract: An AC generator comprises a shaft, a rotor secured to the shaft, a stator with a stator core provided to surround the outer circumference of the rotor and having a plurality of slots formed to extend in the axial direction while spaced apart in the circumferential direction, and a front bracket and a rear bracket surrounding the stator core while clamping the circumferential edge portion of the stator core from the opposite sides in the axial direction using a plurality of clamping means. A pair of front stays formed in the front bracket are secured to a vehicle by means of bolts penetrating a pair of through holes formed, respectively, in the pair of front stays. The pair of through holes are formed at such positions as the perpendicular bisector of a line connecting the centers intersects the axis of the shaft, and one clamping means is provided on the shaft side perpendicular bisector.
