Abstract
A handwheel actuator assembly for a steer-by-wire system of a vehicle comprises a housing, a shaft rotatably mounted to the housing, the shaft connectable to a handwheel, and one or more motors each having a stator and a rotor. The stator carries a plurality of phase windings and the rotor carries a plurality of magnet poles and is connected to the shaft. A control circuit is adapted to control the current flowing into or out of each motor to cause a net torque to be applied to the shaft during normal operation. The stator of at least one of the motors is configured such that in the event that the control circuit is powered down or disconnected and the handwheel is rotated at 180 degrees per second, the combination of motors overall provides a drag torque of at least 50 percent of the resistance to rotation of the shaft and a torque at the handwheel of at least 2 Nm.
