  • Patent number: 8601676
    Abstract: The insertion of electrically insulating paper from a continuous roll into slots of a stator created by outwardly projecting teeth is described herein. The insertion of the insulating paper is done by the insertion of prewound coils in the stator slots. The electrically insulating paper is not cut prior to its insertion in the slots, thereby completely covering the outer surface of the stator. The insertion systems and methods described herein are also optionally concerned with the insertion of interphase insulation paper between the different coils inserted in the stator slots and with the insertion of slot closing wedges.

  • Patent number: 7614910
    Abstract: Described are electrical connectors for hi-power applications where multiple electrical wires are to be maintained apart and electrically insulated from one another. The connectors are to be used to mount the plurality of wires to a receptacle of a casing so as to establish a connection with electric circuit(s) provided inside the casing. Portions of the connector interact with the casing to provide a seal therebetween to prevent the water and dirt infiltration inside the casing.

  • Publication number: 20080197737
    Abstract: An illustrative embodiment of the present invention is concerned with a permanent magnet rotor for an electric machine provided with an internal stator and a coaxial external rotor. To overcome the drawbacks associated with the use of an adhesive to mount the permanent magnets to the rotor body, permanent magnet spacing and retaining elements are mounted to the inner surface of the rotor, between adjacent magnets.

  • Patent number: 7073219
    Abstract: A side rail; a patient support assembly, such a hospital bed, a stretcher and the like, provided with such a side rail; a method of operating associated thereto; and a kit for assembling the side rail. The side rail includes support bars and at least one cross bar being substantially positioned within a same vertical plane, substantially parallel to a corresponding side portion of the assembly. The support bars are rotatable with respect to the corresponding side portion about respective axes being parallel to a transverse axis of the assembly, and first and second ends of the at least one cross bar are rotatable with respect to the support bars about respective axes being parallel to the transverse axis, so that the side rail be operated between raised and lowered configurations along the same vertical plane and so that the side rail be collapsible in the lowered configuration, within the same vertical plane.

  • Publication number: 20050116553
    Abstract: A cooling device for an internal stator of an electric machine. The stator includes a substantially cylindrical cavity having a substantially cylindrical internal surface. The cooling device includes a body defining an external substantially cylindrical contact surface. The cooling device further includes a biasing element connected to the body. The biasing element is so configured and sized as to bias the contact surface of the body against the internal surface of the rotor when the cooling device is positioned inside the cavity.

  • Publication number: 20050110361
    Abstract: A dynamoelectric machine stator core for receiving a pre-formed stator winding includes a core body defining a cylindrical core main peripheral surface. A plurality of axially extending stator slots are circumferentially spaced in the core body. Each of the stator slots defines a slot first section extending radially from the slot base to a slot intermediate radial position and a slot second section extending radially from the slot intermediate radial position towards the core main peripheral surface. The slot first and second sections communicate with each other and are circumferentially offset relative to each other. The slot first and second sections are positioned, configured and sized to facilitate insertion therein of a corresponding conductor section of the stator winding with reduced needs for deforming the latter.
