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.

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.

Patent number: 7527530Abstract: An electric terminal connector block is provided with oblong tool openings that communicate with interior channels of the connector block and with openings in the motor wiring electric terminals positioned in each channel of the connector block. The oblong shapes of the tool openings enable insertion of tool pins through the tool openings and openings of the electric terminals and movement of the tool pins along the lengths of the oblong tool openings whereby the tool pins engage with the electric terminals and move the terminals relative to the connector block to insure that the terminals are locked in place in the connector block. In addition, the tooling used with the connector block is operated according to a method that insures that the terminals of the motor winding are moved to a position relative to the connector block where the terminals are locked in place.Type: GrantFiled: February 15, 2005Date of Patent: May 5, 2009Assignee: Emerson Electric Co.Inventors: Jacob M. Olejniczak, Vincent P. Fargo, Kent L. White, Paul G. Michaels, William L. Riggs, Charles A. Peters

Patent number: 7471025Abstract: A stator assembly has discrete stacks of laminations. A plurality of nonmagnetic containment structures define pockets. The stacks are at least partially received in the pockets and coupled to one another by the containment structure. The containment structures are moveable between a first configuration in which the stacks are separate from one another and a second configuration in which yokes of adjacent stacks are in physical contact with one another. In a method of making a stator assembly, a plurality of stator segments are positioned so each is received in one of a plurality of pockets in a containment structure. Coils are wound around each stator segment while the containment structure prevents the stator segment from having direct physical contact with another stator segment. The containment structure is reconfigured to bring the wound stator segments into contact with one another, thereby forming a closed magnetic circuit.Type: GrantFiled: February 12, 2008Date of Patent: December 30, 2008Assignee: Emerson Electric Co.Inventors: Kent A. Sheeran, Payman Rassoolkhani, Paul G. Michaels
