  • Publication number: 20140056726
    Abstract: In an electric machine, there may be lubrication and cooling needs, such as lubricating bearings and cooling coils of the electric machine. When lubricant is used for both, it is desirable to prioritize the lubrication to the bearings. By providing check valves between a pressurized oil manifold and the cooling coils, lubricant is diverted to the coils only when pressure in the system is sufficient to satisfy both lubrication and cooling. In some embodiments, an oil gallery is provided on an outside surface of a back iron of the stator of the electric machine and orifices are provided in the back iron so that oil drips onto the coils of the electric motor. In some embodiments, the current commanded to the electric motor is based on whether or not lubricant (or other coolant) is being provided to the coils.

  • Publication number: 20140048362
    Abstract: A system and method are provided for mounting, removing and retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles, in a manner which does not require the use of separate brake pad retaining devices while providing positive retention of the brake pad. A preferred embodiment includes a brake caliper mount having brake pad abutment surfaces having radially-oriented and lateral grooves which permit a brake pad with corresponding projections on is lateral sides to be inserted through an opening of the brake caliper into the radially-oriented grooves until the backing plate projections are aligned with the lateral groove, and advancing the brake actuator behind the brake pad to place the brake pad in an operating position in which the actuator prevents the brake pad from realigning with the radially-oriented grooves until the actuator is retracted to permit brake pad extraction.

  • Patent number: 8613966
    Abstract: A rippled wafer (90) formed of a convoluted wafer ribbon (80), the rippled wafer (90) having an average of at least 12 turns/cm2, wherein a turn is a change in direction of the wafer ribbon (80) of at least 45°, and a confectionery product comprising such a wafer. Also a confectionery product comprising a rippled wafer (90) formed of a convoluted wafer ribbon (80), wherein the turns are substantially uniformly distributed across the cross section of the rippled wafer, where a turn is a change in direction of the wafer ribbon of at least 45°, and a confectionery product comprising a three-dimensional rippled wafer (90) formed in a single step.

  • Patent number: 8344576
    Abstract: A rotor for use in an electrical motor which includes an anti-expansion ring centrally mounted on the rotor to restrict the extent rotor elements mounted on a rotatable shaft may expand outward due to centrifugal forces generated when the motor is operated. Such motors are suited for use in high rotational speed environments such as electrically controlled turbochargers.

  • Publication number: 20110241473
    Abstract: A rotor of an electric machine is disclosed that resists expansion of the rotor components even at high rotational speed. The rotor includes first and second pluralities of laminations having slots to accept rotor bars. A support disk, also having slots, is placed between the laminations. The support disk, into which the rotor bars are slid, restrains the rotor bars from bending outwardly at high rotational speeds of the rotor. The rotor bars are further restrained at the ends by end rings, which have apertures into which ends of the rotor bars are placed. In some embodiments, containment rings are placed over axial extension of the end rings to prevent outward bowing at high speeds. In some embodiments, the rotor includes a stiffener sleeve to provide additional resistance to expansion during high rotational speeds.
