  • Actuator with automatic force setting and self-calibration
    Patent number: 11973445
    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.
    Type: Grant

  • Automatic actuator calibration using back EMF
    Patent number: 9509243
    Abstract: A self-calibrating linear actuator is configured to control a spring return valve with variable stroke. The actuator includes a motor, a spindle coupled to an output of the motor, a motor controller coupled to the motor, a microcontroller coupled to the motor controller, and a back electromotive force (BEMF) circuit, coupled to the motor, configured to provide to the microcontroller a BEMF value for each motor step. The microcontroller is configured to determine a difference of a number of motor steps during operation of the actuator and to store the difference as a calibrated touch point for the actuator.
