The drive system includes two or more asynchronous electric motors (M1,M2) which are supplied with power in parallel from a central electric power source (2). The central electric source is managed by a controller (6) that delivers a first command signal (SCF) determining the value of supply frequency (FAL) and a second command signal (SCA) determining the amplitude (UAL) of the supplied potential. These two command signals are regulated as a function of a measure (SMI) of the main supply current, a set speed signal (SCS) and a signal (SFMX) representing the maximum rotational frequency of the rotors of the motors. |
