Abstract: A apparatus may be configured to select a number of windings for a motor of a handwheel actuator; short a subset of windings of the number of windings; determine a resistance value for the motor; and selectively adjust, based on a number of windings associated with the subset of windings and to tune a damping characteristic associated with the handwheel actuator, the resistance value by varying at least one of (i) a number of winding turns associates with the subset of windings, (ii) a wire diameter of associated with the subset of windings, (iii) a number of wires associated with the subset of windings and (iv) a material associated with the subset of windings.

Abstract: A transverse flux machine (TFM) includes: a rotor configured to rotate about an axis and having a plurality of pairs of permanent magnets, with flux concentrating and flux diverging cores alternatively placed between the permanent magnets, each of the pairs of permanent magnets arranged to generate a magnetic flux in a circumferential direction into the flux concentrating core and away from the flux diverging core; and a stator including a transverse flux core configured to direct the magnetic flux in each of a radial direction and an axial direction. The rotor further includes a non-magnetic material located between the permanent magnets of each of the pairs of the permanent magnets, adjacent to the flux concentrating core and opposite from the stator, the non-magnetic material having a thickness (TH) in a radial direction. A steer-by-wire system for a vehicle includes a handwheel actuator including a TFM coupled to a steering wheel.

Abstract: A method for passive damping in a steer-by-wire handwheel actuator. The method includes winding a first coil around a first tooth of a motor, winding a second coil around a first tooth of the motor, and shorting the second coil to one of an internal aspect of the motor and an external aspect of the motor.

Abstract: A method for passive damping in a steer-by-wire handwheel actuator includes selecting a number of windings for a motor of a handwheel actuator; shorting a subset of windings of the number of windings, each winding of the subset of windings being disposed at an obtuse angle from each other winding of the subset of windings; determining a resistance value for the motor; selectively adjusting the resistance value based on a number of windings associated with the subset of windings; and providing, in series with the subset of windings, at least one metal-oxide-semiconductor field-effect transistor (MOSFET) configured to: vary the resistance associated with the subset of windings based on a vehicle speed; and tune a damping characteristic associated with the handwheel actuator.

Abstract: A system includes an electric motor, a rotor associated with electric motor, a first pole of the rotor, and a first magnet stack associated with the first pole. The first magnet set includes a set of magnets disposed proximate the rotor arranged according to a skewed arrangement and including at least a first magnet having a first length, a second magnet having a second length, and a third magnet having a third length.
