  • Supplemental electromagnetic turbocharger actuator
    Patent number: 9951683
    Abstract: A turbocharger system for an engine includes a rotor, a primary bearing system arranged to axially and radially support the rotor to rotate on a central rotational axis, a compressor coupled to a rotor to rotate with the rotor, a turbine coupled to the rotor to rotate with the rotor, and an electromagnetic actuator adjacent to the rotor. The electromagnetic actuator selectively acts on the rotor and supplements the axial support of the primary bearing system by applying a magnetic force on the rotor in a direction parallel to the central rotational axis of the rotor.
    Type: Grant
