ABSTRACT:
Controlling and adjusting of the operation of a device actuated by an electric motor are carried out by shutting down the electric power supply of said electric motor at a plurality of time intervals during the motor operation, measuring in the time interval the voltage supplied by the electric motor, comparing the value of the measured voltage with a reference value and, if required on the basis of said comparison, varying at least one parameter related to the functioning of the device in order to compensate possible deviations.
