Abstract: The present disclosure relates to a method for measuring a damping function, for example of a damper of an electromechanical actuator or drive system, and to an actuator or a drive system comprising a control unit which is configured for carrying out a method according to the disclosure. The method comprises the steps of actively accelerating a motor to a defined speed n, activating an isolation function and/or switching off a converter and/or configuring the converter for generating a short circuit of the connected phases, and determining a current step response of the motor.

Abstract: The disclosure relates to an actuator with redundant channels, comprising a motor; a sensor for detecting and transmitting a speed signal from the motor; a first and second channel each having a functional unit connected to the sensor for operating the actuator; a selection unit for selecting whether the first or the second channel controls the actuator, and a motor information unit. Each of the first and second channels supplies a speed information value based on the speed signal to the selection unit. The motor information unit provides a third speed information value of the motor to the selection unit. The selection unit is designed to make a decision on the speed information values as to whether the first channel or the second channel is given control of the actuator.

Abstract: The disclosure proposes a drive system for an actuator, comprising an electric motor for actuating the actuator, a first and second drive electronics unit designed to provide electric power to a motor connection for driving the electric motor, a first isolating device arranged between the first drive electronics unit and the motor connection and configured to selectively electrically isolate the first drive electronics unit from the motor connection, a second isolating device arranged between the second drive electronics unit and the motor connection and configured to selectively electrically isolate the second drive electronics unit from the motor connection, and a damping unit. The first drive electronics unit and the second drive electronics unit are redundant to each other. The damping unit is designed to detect the state of the first and second isolating devices and to cause damping of the electric motor when both are activated.

Abstract: The present disclosure relates to a method for controlling and/or determining a position of an actuator, in particular of an aircraft, wherein the actuator has a control unit, a motor and a motor position sensor for determining a position of the motor, wherein the control unit controls and/or determines the position of the actuator using the position of the motor and/or a sensor signal from the motor position sensor.
