摘要： A stator has a plurality of segments connected with connectors to define a core for the stator. Each of the segments comprises a plurality of laminations arranged side by side forming a lamination stack with axially opposite sides. The lamination stack has an end cap abutting an axial side of the lamination stack. The end cap has first and second posts extending axially therefrom. At least one of the posts defines a wire path for wire wound around the stack. Each of the connectors comprises a bridge portion. The bridge portion has openings dimensioned to receive the posts in a manner that the connector is removably attachable to the post of the end cap of a segment and the post of the end cap of an adjacent segment. The connector has an insulator portion projecting from the bridge portion. The insulator portion extends between adjacent segments.

摘要： A rotating flux vector is set up in a motor or generator's rotor by simultaneously energizing two phase windings while the rotor remains stationary, wherein each phase winding may be energized by the same or different excitation voltages. Respective tap voltages are then recorded at this first flux position. Thereafter, the two phase windings are simultaneously energized by another voltage excitation, wherein each phase is energized at the same or different voltages, causing a new flux position to occur. Once again, respective tap voltages are recorded. This process may be repeated for various rotations of the motor's flux. The measured tap voltages are evaluated to determine the location of the rotor, without actually moving it. The present invention is applicable to SR and non-SR machines having a plurality of phases and pole configurations.

摘要： A rotor comprises laminations with a plurality of rotor bar slots with an asymmetric arrangement about the rotor. The laminations also have magnet slots equiangularly spaced about the rotor. The magnet slots extend near to the rotor outer diameter and have permanent magnets disposed in the magnet slots creating magnetic poles. The magnet slots may be formed longer than the permanent magnets disposed in the magnets slots and define one or more magnet slot apertures. The permanent magnets define a number of poles and a pole pitch. The rotor bar slots are spaced from adjacent magnet slots by a distance that is at least 4% of the pole pitch. Conductive material is disposed in the rotor bar slots, and in some embodiments, may be disposed in the magnet slot apertures.

摘要： A coupling transmits torque between two shafts approximately aligned on a shaft axis. The coupling has a center axis approximately aligned with the shaft axis. The coupling comprises arcuate coupling segments with ends extending generally parallel to the coupling center axis and arcuate portions extending between the ends. The arcuate coupling segments are arranged in a ring with adjacent segments being arranged end to end to form the coupling. Each coupling portion comprises a first clamp ring adapted to be operatively attached to a shaft and a second clamp ring adapted to be operatively connected to another shaft. Elastomer material extends between both clamp rings. The elastomer material extends axially and circumferentially on each clamp ring in areas adjacent to each end of the arcuate coupling segment.

摘要： A roller bearing cage has a cage element (20) adapted for retaining the generally cylindrically shaped rollers (30) and allowing the rollers to be rollable therein. The cage element includes a main portion (22) having a plurality of pockets (28), an outward flange portion (24) extending outwardly in a radial direction and an inward flange portion (26) extending outwardly in the radial direction. The outward flange portion (24) is formed on a side edge of the main portion and the inward flange portion (26) is formed on an opposite side edge portion thereof. The main portion (22) defines the smallest diameter of the bearing cage and is less than the roller pitch diameter (D4). The outward flange portion may also include an outward flange guide surface for guiding barrel-shaped rollers. The guide surface is cylindrical in shape and adjacent each pocket. The guide surface is adapted to abut an axial end of the rollers.

摘要： A bearing is disclosed. The bearing has an inner ring concentrically disposed with an outer ring with rotational elements therebetween adapted for allowing rotational movement of the inner ring relative to the outer ring. The outer ring has a crowned outer surface. A waveform expansion sleeve is disposed about the outer ring. The waveform expansion sleeve has a cylindrical outer surface dimensioned to be received in a bore of a bearing housing and an inner surface with a profile matching the outer ring outer surface. The waveform expansion sleeve has an undulating radial cross-section sufficient to exert radial pressure at its inner surface against the outer ring outer surface when mounted in the bore of the bearing housing to sufficiently secure the bearing in the housing. The expansion sleeve inner surface forms a seal with the outer ring outer surface when the bearing is installed in the bearing housing.
