A method of driving for automatic machines, particularly for high-speed automatic machines consisting of a number of working units with alternate operation with synchronisation between the units, such as packing machines for cigarettes or similar, in which method the individual working units are driven by a single main electric motor (M) by means of associated transmission chains (3). According to the invention the variations of load on the main motor during the operating cycle of the machine are at least partially compensated for by the storage, in the form of reversible electrolytic energy, of the restored electrical energy of the main motor (M) in the phases of the machine cycle in which the resistant torque is inverted, and of the part of the electrical energy which is not supplied to the motor in the phases of the machine cycle in which the resistant torque is less than the mean value, and by the restoration of the said reversible electrolytic energy in the phases of the machine cycle in which the resistant torque exceeds the mean value. <IMAGE> |
