The inventive method is used for controlling a synchronised operation of at least two polyphase electric motors. Each motor comprises a stator (4) provided with electric coils (5) and a rotor (8) having N pairs of poles which are radially magnetised in an alternate direction. Said method is characterised in that the position of the rotor (8) of motors (2, 3) is determined with the aid of a detection means (12), one-time power supply sequencing for phases (6) of the motors (2, 3) is defined the with the aid of a logical synchronisation electronic means (19) and said defined power supply sequencing is identically applied to the coils (5) of the motors (2, 3) phases (6) with the aid of a power electronic means (18). A driving device for carrying out said method is also disclosed.
