Method for controlling an electric motor driving a body in translation
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.
