Patent number: 7919898Abstract: A rotor core assembly for an electric motor includes a stack of laminations and first and second end plates disposed at opposite ends of the stack of laminations. A plurality of concentric fastener holes extend through the laminations and the end plates for receiving stainless steel pins. Each pin has a head against one of the end plates, and each pin has spaced apart grooves thereon extending from the other end plate. A stainless steel collar engages each of the pins and contacts one of the end plates. Each collar has a deformed portion in at least one of the grooves of the pin.Type: GrantFiled: June 21, 2007Date of Patent: April 5, 2011Assignee: Nidec Motor CorporationInventors: Weirong Wang, Thomas E. Kirkley, Jr.

Patent number: 7586231Abstract: A stator for an electromagnetic machine includes a plurality of discrete and individually wound stator segments having end caps positioned on the segments. The end caps have legs for positioning the end cap on the segments with an interference fit. The end caps have angled surfaces to facilitate winding of wire on the segments. The end caps have male and female couplings that mate together to couple adjacent segments together. The end caps have fingers and slots for aligning the segments on substantially the same plane. The end caps have wire isolation features, including hooks, shelves and ledges, for separating the interconnect wires routed on the stator to electrically interconnect the segments. The segments include scalloped contours on their outer edges for draining oil, and the end caps have passages for draining oil.Type: GrantFiled: August 18, 2008Date of Patent: September 8, 2009Assignee: Emerson Electric Co.Inventors: Weirong Wang, John Scott Rose, Paul G. Michaels, Mark E. Carrier, Jason J. Jurkowski

Patent number: 7578047Abstract: A method of stitching a plurality of interconnect wires on a stator of an electromagnetic machine is disclosed. The stator includes a plurality of discrete and individually wound stator segments having end caps positioned on the segments. The end caps have wire isolation features, including hooks, shelves and ledges, for separating the interconnect wires routed on the stator to electrically interconnect the segments. The method includes routing the interconnect wires between portions of the stator such that portions of the interconnect wires overlap and separating the overlapping portions in an axial direction with the wire isolation elements.Type: GrantFiled: October 2, 2006Date of Patent: August 25, 2009Assignee: Emerson Electric Co.Inventors: Weirong Wang, Paul G. Michaels, John Scott Rose, Mark E. Carrier, Jason J. Jurkowski
