Abstract: The invention concerns a method for controlling an electric motor driving a body in translation between an initial position and a final position determined by a stop, by powering the motor with reduced voltage in the final position approach phase. The motor has a torque/speed characteristic such that the torque at null speed decreases with the supply voltage. As the approach phase starts, the method consists in determining a reduced voltage by decreasing the rotational speed of the motor from a nominal value to a predetermined reduced value and in cutting the motor power supply if the motor rotational speed drops below a predetermined threshold value.

The method is characterized in that it consists in transferring to another unit, called the remote processing unit, all or part of the processing for analyzing measurements relating to said actuator and/or to said movable element.

Abstract: The invention concerns a powered rolling shutter whereof the stator of the motor is connected to a fixed support via elastic means (R1, R2) for stopping the shutter in high and low abutment when the resisting torque exceeds a selected value, consisting of two springs (R1, R2) compressed by the stator rotation. The travel distance (12) before on of the springs (R2) is compressed is greater than the travel distance (11) before the other spring (R1) is compressed.

The motor can be mounted on the left or on the right with a differentiated resisting torque for stopping in high abutment and low abutment.
