Abstract: Systems and methods for auto-calibration of current supplied to a motor of an actuator may include supplying an initial electrical current to the motor. One or more sensors may measure a condition corresponding to the motor as the initial electrical current is supplied to the motor. A processing circuit may compare the measured condition to an expected condition. The processing circuit may adjust a supply of the initial electrical current to the motor until the measured condition substantially matches the expected condition. The processing circuit may store data regarding an association between the adjusted supply of initial electrical current and the expected condition.

Abstract: The present disclosure relates to an actuator comprising an actuating arm, a magnetic slider to select one of a plurality of stroke positions of the actuating arm, one or more sensors to determine a selected stroke position, and a processing circuit. The processing circuit operates the actuating arm based on the selected stroke position.

Abstract: Systems and methods for controlling a movable component using back electromotive force (BEMF)-based feedback are described. The system includes an actuator operatively coupled to the movable component. The actuator includes a motor for driving the movable component. The actuator includes a BEMF circuit for measuring a BEMF produced by the motor while driving the movable component. The system includes a processing circuit communicably coupled to the motor and the BEMF circuit. The processing circuit receives, from the BEMF circuit, a BEMF signal generated by the BEMF circuit as the motor drives the movable component. The processing circuit determines, based on the BEMF signal, an active range of the motor which corresponds to a full stroke of the movable component. The processing circuit controls the motor to drive the movable component within the active range.
