Abstract

The device includes two driving circuit (C1, C2) each of which includes six power transistors (T11-T16, T21-T26) that are connected in pairs into three parallel circuit branches. A first coil (B11) of one of the motors and a first coil (B21) of the other are, on the one hand, both connected to the junctions of the transistors of one of the branches of one of the driving circuits (C1) and, on the other hand, respectively connected to the junctions of the transistors of the two other branches of this circuit. The same applies for the second coils (B12, B22) of the motors and the other driving circuit (C2). The various transistors are controlled so that the two coils of the same motor simultaneously receive the current pulses which are needed to make it turn but by preventing the simultaneous application of current pulses to a coil from one of the motors and to a coil from the other. This arrangement makes it possible to save four transistors and two output terminals on the integrated circuit used to control the motors.
