Abstract

The present control device is used in connection with a diphase or polyphase stepper motor in which the coils of two phases (bi, bj) are not simultaneously supplied with driving current. A commutation circuit CC is adapted to connect the coils to a voltage source V or to a detection circuit CD. A logic control circuit CL1, CL2, CL3, itself controlled by a clock signal source G1 and by a generator of programmed control pulses PG, supplies control signals to said circuits CC and CD. The control device provides a feedback control of the motor as a function of the speed and the position of the rotor at various instants of the control cycle in accordance with a predetermined program so as to assure perfectly reliable operation of the motor with a minimum of electric energy even for motors manufactured with rather wide manufacturing tolerances.
