System for driving motors for operating switching units, in particular for an electrical supply substation, comprising control units for controlling the motors, wherein the control unit comprises, to have only one of the motors in operation at a time, a device for managing the priority of operation of the motors which is provided with a first line, referred to as the parallel line, carrying a binary datum comprising a first state representative of the stopping of all of the motors and a second state representative of the operation of any one of the motors, to which the units are connected in parallel, the parallel line being connected to a device for preventing/allowing the starting of the motor of each of the units and a second line, referred to as the series line, to which the units are connected in series in an upstream/downstream chain, the series line constituting a means for preventing the operation of the motors downstream of the any one of the motors on detection of a signal for starting the any one of said motors, to which the units are connected in series, the series line being connected to a device for preventing the operation of the motor of each of the units.
