  • Publication number: 20220221052
    Abstract: An electro-mechanical actuator for generating an axial actuation force is provided. The electro-mechanical actuator includes an electric machine having a stator (1) and a rotor (2). The electro-mechanical actuator also includes a spindle drive with a rotary element (6) and with an element that is movable in a translatory manner. A rotation of the rotary element (6) may result in a translatory motion of the element that is movable in a translatory manner. The rotor (2) and the rotary element (6) of the spindle drive are coupled to each other in a circumferential direction (U) such that a rotation of the rotor (2) results in a rotation of the rotary element (6) of the spindle drive (5). A rotational play (8) is formed between the rotor (2) and the rotary element (6) of the spindle drive in the circumferential direction (U).

  • Patent number: 11312200
    Abstract: A method for actuating an actuator device of a roll stabilizer for a vehicle. The actuator device has a supply line connection for supplying a supply voltage, a converter for supplying an alternating voltage using the supply voltage, and at least two phase lines for supplying the alternating voltage to actuator connections of an actuator which can be operated using the alternating voltage. The method has a step of reading an interruption signal, which indicates an interruption in the supply of the supply voltage or a deviation from the supply voltage at the supply line connection and a step of providing a protection signal at an interface with a protection device using the interruption signal in order to at least partly prevent a generator voltage which is or can be fed into the phase lines via the actuator connections from being forwarded in response to the protection signal.

  • Publication number: 20210061050
    Abstract: A method of operating an adjustable roll stabilizer (1) of a motor vehicle. The adjustable roll stabilizer (1) has an actuator (2) which can be rotated through a system angle (?) relative to a rotational axis (3) in order to twist two stabilizer sections (6a, 6b), connected thereto, relative to one another. The stabilizer sections (6a, 6b) are each a radial spaced away from the rotational axis (3) and each is coupled to a wheel suspension (7a, 7b, 8a, 8b, 9a, 9b). The method includes controlling the actuator with a field-orientated regulator (20) as a function of input signals which include at least a target motor torque (21), and checking the control of the actuator (2), brought about by the field-orientated regulator (20), for plausibility independently of the field-orientated regulator (20).

  • Publication number: 20190054792
    Abstract: The invention relates to a method for actuating an actuator unit (102) of a roll stabilizer for a vehicle (100), wherein the actuator unit (102) has a supply line port (118) for supplying a supply voltage, a converter (112) for supplying an alternating voltage using the supply voltage, and at least two phase lines (114, 116) for supplying the alternating voltage to actuator ports (132, 134) of an actuator (110) which can be operated using the alternating voltage, comprises a step for importing an interrupt signal (140), which indicates an interruption (130) in the provision of the supply voltage or a deviation from the supply voltage at the supply line port (118) and a step providing (203) a protection signal (142, 144, 146, 148) in response to the protection signal (142, 144, 146, 148) at an interface having protection equipment (152, 154, 156, 158) using the interrupt signal (140) in order to at least partly prevent a generator voltage from being transmitted, which is fed or can be fed into the phase lines

  • Publication number: 20170163185
    Abstract: A method for sensorless commutation of a BLDC motor is presented, wherein the following steps are executed.In step 1, the voltage of a currentless phase is sampled in predetermined time intervals. In step 2, the voltage of the zero crossing, and the associated rotational rate, is determined on the basis of the time difference between two sampling points, and the point in time of the zero crossing is supplied to a commutation timer K, when a zero crossing has been detected between two sampling points. In step 3, the time until a predefined angular rotation of the motor is calculated on the basis of the determined rotational rate, and this time is transmitted to the commutation timer. In step 4, the commutation is initiated and the commutation time is reset when the time transmitted to the commutation time has elapsed.
