摘要： End windings of the field windings of a generator rotor body are flattened. A cap having a flat undersurface overlies the flattened end windings and an enclosure ring extends about the end windings and cap. Apertures are formed through the cap in communication with gaps between the coils of the end windings and passageways formed along the outer surface of the cap. The passageways and apertures form ventilation paths for a cooling medium flowing through the end windings outwardly into the air gap between the rotor body and stator.

摘要： A rotor in an electrical machine, the rotor comprises a magnetic core having at least two poles, a plurality of winding assemblies, one for each pole, and a cylindrical tube enclosing the magnetic core and winding assemblies, the tube including a plurality of rings having different axial widths. Each of the rings is axially spaced apart from an adjacent ring. The respective axial widths of the rings become progressively smaller than the axial width of the ring axially located at or near the center of the tube as the axial distance away from the center of the tube increases. A plurality of winding braces are coupled to at least one of the winding assemblies, the winding braces having different radial heights.

摘要： Locking strips secure winding modules to a rotor. The locking strips have paired deep and shallow recesses along a long edge and are disposed in a groove along the rotor. Upon assembly of the winding module, the deep recesses of the locking strips are aligned, enabling the winding supports of the winding module to engage in the deep recesses. The strips are then axially displaced in opposite directions relative to one another to engage portions of the strips within grooves of the winding supports and edges of the shallow recesses to straddle the winding supports. Pins are received in aligned holes of the locking strips in the locked configuration. Consequently, the modular winding is retained against axial and peripheral movement and outward displacement along a parallel face of the rotor shaft.

摘要： A multi-pole electric machine rotor assembly includes a rotor forging including a rotor body having poles 13 with pole faces and a winding module including a plurality of field windings positioned adjacent the pole faces and winding insulators disposed between each successive pair of the field windings, respectively. A winding block, disposed in engagement with the winding module, is shaped to be shifted to a final position relative to the winding module when the rotor assembly rotates at about its rated speed to thereby compress the winding module. Either the winding block or the winding module can be displaced by centrifugal forces during rotation. In the final position, the winding block is locked by friction in a position to maintain compression in the winding module. The winding block serves to provide a pre-stress in the field windings to keep the field windings tight over the design range of spin speeds, thereby controlling winding position and reducing alternating radial movement.

摘要： A winding module for an electric machine is provided wherein the winding module comprises a flat field winding that is angled at an end turn and wherein a vertex of the flat field winding is aligned with an axis of rotation. The vertex provides a predetermined axial offset so as to compensate for a radial expansion of the flat field winding when it is disposed to a centrifugal force.

摘要： A generator rotor includes a rotor body having defined pole regions with pole faces and parallel sides adjacent the pole faces. A winding module is fitted over the parallel sides of the rotor body, and a pair of spindles are secured to respective ends of the rotor body. The spindles secure opposite sides of the winding module to the rotor body. The spindles preferably include a notch that is shaped to receive one side, respectively, of the winding module. With this construction, flat windings can be used for the winding module, eliminating the need for a curved module to fit over the spindle.
