A hand wheel actuator assembly for a steer-by-wire system of a vehicle, the hand wheel actuator assembly comprising: a housing; a shaft rotatably mounted with respect to the housing, the shaft being connectable to a hand wheel; one or more motors each having a stator carrying a plurality of phase windings and a rotor carrying a plurality of magnetic poles and connected to the shaft; a control circuit adapted to control the current flowing into or out of the or each motor to cause a net torque applied to the shaft during normal operation, and wherein the stator of at least one of the motors is configured such that, in the event that the control circuit is de-energized or disconnected and the handwheel is rotated at 180 degrees per second, the stator of the at least one of the motors is deenergized or disconnected and the handwheel is rotated at 180 degrees per second. The combination of these motors generally provides a resistance moment of at least 50% of the rotational resistance of the shaft and provides a torque of at least 2 Nm at the hand wheel.

    一种用于车辆的线控转向系统的手轮致动器组件,该手轮致动器组件包括:壳体;轴,该轴相对于壳体可旋转地安装,轴可连接到手轮;一个或多个马达,每个马达具有定子和转子,该定子承载多个相绕组,并且该转子承载多个磁极并连接至轴;控制电路,该控制电路适于控制流入或流出该马达或每个马达的电流,以在正常操作期间引起施加到轴的净转矩,并且其中这些马达中的至少一个马达的定子被配置成使得在控制电路断电或断开连接并且手轮以每秒180度旋转的情况下,这些马达的组合总体上提供轴的旋转阻力的至少50%的阻力矩并在手轮处提供至少2Nm的转矩。
