  • Publication number: 20200343788
    Abstract: An electric motor comprising: a first element having at least one electromagnet, a second element, rotatable relative to the first element about an axis, the second element comprising at least one permanent magnet, wherein the electric motor is arranged to generate a torque by applying a rotating magnetic field to the second element, and a friction member coupled to the first element such that the friction member is non-rotatable relative to the first element about the axis, the friction member comprising a magnetically susceptible material and being biased by a first biasing force toward the second element, wherein the first element, the second element and the friction member are configured such that: when the electromagnet is not energised, the first biasing force causes the friction member to contact the second element to generate a braking torque.

  • Publication number: 20200282552
    Abstract: The application relates to a magnetic biasing assembly. The magnetic biasing assembly comprises an outer part, having a first permanent magnet and an outer ferromagnetic annulus disposed radially outwardly of the first permanent magnet; and an inner part, having a second permanent magnet and an inner ferromagnetic annulus disposed radially inwardly of the second permanent magnet. The outer and inner parts are rotatable relative to each other about an axis to move the inner and outer parts into and out of an equilibrium position with each other. When the inner and outer parts are moved out of the equilibrium position, the first and second permanent magnets are arranged to generate a magnetic restoring moment between the inner and outer parts in a direction towards the equilibrium position.

  • Publication number: 20200220403
    Abstract: A permanent magnet carrier, which could be a rotor or stator of an electric machine, includes a first non-magnetic ring and a second non-magnetic ring. Between the rings are soft magnetic pole elements. The soft magnetic pole elements each connect to the first and second non-magnetic rings and the soft magnetic pole elements are separated from each other by the first and second non-magnetic rings. Permanent magnets are disposed between the soft magnetic pole elements.

  • Publication number: 20200076279
    Abstract: A stator has a backiron and a plurality of posts. The backiron and plurality of posts are collectively at least partially formed from a monolithic soft magnetic material. The plurality of posts define an cross-sectional outline that is larger than the at least portion of the plurality of posts that is formed from the monolithic soft magnetic material.

  • Publication number: 20200011329
    Abstract: In a rotor in rotor configuration, a pump has inward projections on an outer rotor and outward projections on an inner rotor. The outer rotor is driven and the projections mesh to create variable volume chambers. The outer rotor may be driven in both directions. In each direction, the driving part (first inward projection) of the outer rotor contacts a sealing surface on one side of an outward projection of the inner rotor, while a gap is left between a sealing surface of the other side of the outward projection and a second inward projection. The gap may have uniform width along its length in the radial direction, while in a direction parallel to the rotor axis it may be discontinuous or have variable size to create flow paths for gases.

  • Publication number: 20160025152
    Abstract: A clutch designed to effectively transfer torque between wheel drive system components in a vehicle drive wheel drive system to move the vehicle on a ground surface is provided. The wheel drive system components may include a non-engine drive means and a roller traction drive in torque transmission contact with the clutch and with the vehicle drive wheel. The clutch includes complementarily configured clutch components designed to mesh into engaging contact when activated by electromagnetic or other external engagement actuation means to transfer torque through an interface to a vehicle wheel. Drag and friction produced by activation of adjacent rotating patterned clutch elements amplifies axial forces to cause clutch elements to mesh into locking engagement to control transfer of torque between a non-engine drive means and a roller traction drive system to drive an aircraft landing gear wheel or other vehicle wheel.

  • Patent number: 9061623
    Abstract: A container for use on a dump truck style transport trailer is described, and specifically a container for transporting a fluid mixture such as a slurry or sludge is described. The container has interior hinging baffles for dividing the container into compartments and preventing the contents in the container from moving around during transport. The container has a tailgate that is connected to the baffles such that pivoting the tailgate causes the baffles to pivot. The container also includes a sealable lid that can be opened for loading contents into the container and closed for preventing spillage of the contents during transportation. A cleaning system and heating system for the container are also described.

  • Publication number: 20130066332
    Abstract: A biopsy tool for MR imaging for operation by a robot arm is formed of relatively brittle ceramic materials which have a magnetic susceptibility which is substantially equal to that of human tissue. The tool has designed slip couplings and bend joints to prevent overloading of forces on the sampling jaws. Cleaning ports are integrated into the design so that sterility can be obtained by flushing the device interior with a cleaning fluid. A novel spring-loaded capstan operated by a crank movable longitudinally of the tool ensures proper cable tension. A unique jaw shape enables a cutting pressure to be applied simultaneously around the desired tissue and does not depend on sharp edges to obtain the sample. Springs in the main casing provide cable tensioning to keep the jaws in a default closed position for movement of the biopsy device along a trajectory to the sample to be acquired.

  • Publication number: 20070049449
    Abstract: A power transfer device uses the differential ball principle or friction gear with friction reducing features for a given output torque capacity. The friction gear may be used in high output torque applications with an acceptably low torque requirement at the input. The power transfer device incorporates a two stage differential ball device or friction gear. If a second stage is used as a reduction stage, then a pre-reduction stage may be added. The device also includes an integrated stabilizing thrust bearing, high ball count, and material selection for reduced friction.

  • Publication number: 20060204394
    Abstract: A pump comprises a driving rotor and a driven rotor that are positioned in a housing such that, as the driving rotor and the driven rotor rotate, the teeth of the driving rotor and the teeth of the driven rotor mesh to form a positive displacement seal. The teeth of the driving rotor and the driven rotor are configured such that seals between the inlet side and the discharge side of the pump are formed between only the leading surfaces of the teeth of the driving rotor and the trailing surfaces of the teeth of the driven rotor.
