Publication number: 20110273055Abstract: A retainer in the stator of an electrical machine holds a plurality of stacked stator laminations in compression at an inner diameter of a stator core. The plurality of laminations have a central aperture and a plurality of teeth circumferentially spaced about the central aperture. The plurality of stacked laminations forms a contiguous stator core with a central aperture for housing a rotor and stator winding slots extending from one axial face of the stator core to an opposite axial face of the stator core. The retainer is adapted to be fitted in the stator slots adjacent the windings and adjacent the central aperture. The retainer extends from one axial face of the stator core to the opposite axial face of the stator core. The retainer has opposite longitudinal ends abutting the axial opposite faces of the stator core that hold the laminations in compression.Type: ApplicationFiled: May 6, 2010Publication date: November 10, 2011Applicant: BALDOR ELECTRIC COMPANYInventor: Wayne A.

Patent number: 6288460Abstract: A fluid-cooled switched reluctance motor, comprised of a stator having a plurality of evenly spaced, radially oriented, like stator poles that define a gap between adjacent stator poles. The stator poles have side walls that are dimensioned wherein adjacent side walls on adjacent stator poles are parallel. Windings are wound about the stator poles, adjacent windings forming a slot of uniform cross-section therebetween. A rotor element is mounted for rotation relative to the stator. The rotor has a plurality of equally spaced, radially oriented like rotor poles. An elongated cooling tube is disposed within each of the slots defined between the windings. The cooling tube has a first end and a second end, and is dimensioned to essentially fill the slot between adjacent windings. A first coolant chamber is disposed at a first end of the stator, and a second coolant chamber is disposed at a second end of the stator.Type: GrantFiled: November 3, 1999Date of Patent: September 11, 2001Assignee: Baldor Electric CompanyInventors: Joseph P. Fakult, Wayne A. Pengov, Gerald A. Dissauer

Patent number: 6114789Abstract: A switched reluctance motor comprised of a stator having a plurality of evenly spaced, radially oriented, like stator poles that define a gap between adjacent stator poles. Windings for three phases are wound about the stator poles wherein a stator pole of a first phase is disposed circumferentially between a winding and an associated stator pole of a second phase and a winding and an associated stator pole of a third phase. A rotor is mounted for rotation relative to the stator. The rotor has an even number of rotor poles, the rotor poles being dimensioned such that when one of the phases is energized, the rotor poles operatively interact with the energized stator poles such that the motor moves from a first state wherein half of the rotor poles are magnetically coupled to a like number of the stator poles to a second state wherein all of said rotor poles are magnetically coupled to a like number of stator poles.Type: GrantFiled: November 22, 1999Date of Patent: September 5, 2000Assignee: Tridelta Industries, Inc.Inventors: Wayne A. Pengov, Douglas L. Carr

Patent number: 6060809Abstract: A switched reluctance machine includes a first element having a plurality of uniform poles and a second element having a first pole and a second pole. The first pole has a wide face and the second pole has a narrow pole face. The first and second elements are disposed for movement relative to each other such that the wide and narrow poles are moveable in spaced relation to the plurality of uniform poles.Type: GrantFiled: October 13, 1998Date of Patent: May 9, 2000Assignee: Tridelta Industries, Inc.Inventor: Wayne A. Pengov

Patent number: 6054819Abstract: A driving circuit for a multi-phase switched reluctance (SR) machine, wherein a reduced number of wire connections between the machine and driving circuit are needed. In addition, one embodiment of the driving circuit requires the use of fewer individual diodes for the circuit design. The reduction in the number of wire connections and diodes provides greater reliability, improved efficiency, and lower production costs.Type: GrantFiled: May 15, 1998Date of Patent: April 25, 2000Assignee: Tridelta Industries, Inc.Inventor: Wayne A. Pengov
