Abstract:
Methods of compensating for play and for initializing a position encoder in an actuation system ( 2 ) including an actuated system ( 8 ) comprising an elastic element, and an actuator ( 4 ) with a stepper motor ( 12 ) having at least one electrical phase.

Claim (Index 46):
An actuator comprising a stepper motor ( 12 ) having at least one electrical phase, a controller ( 10 ), a rotor position sensor, a back EMF voltage sensor, a current sensor, and a motion transmission system ( 14 ) configured to be coupled to an actuated system ( 8 ), wherein\n the controller is configured to supply a current to said at least one electrical phase to accelerate a rotor of the stepper motor during an acceleration phase and subsequently switch off the supply current in said at least one electrical phase, the back EMF voltage sensor is configured to measure a back EMF voltage in said at least one electrical phase with the supply current switched off and the rotor position sensor is configured to determine therefrom a mechanical position of the rotor when the back EMF voltage measurement reaches a pre-defined value, and the controller is configured to control the stepper motor to align a mechanical position of the rotor with an electrical angle of said at least one electrical phase at said position when the back EMF voltage reaches a pre-defined value.
