Abstract
New digital control device, applicable in direct current motors, which consists in a first design of enabling rotation of a motor 1 in both directions practically automatically without sparks, by means of four thyristors 4, 5, 6 and 7, a diode 3 in reverse position neutralizing any induced surge currents and an impedance 2, surrounded by four thyristors 8, 9, 10 and 11 inserted in series, the current circulating from positive to negative.
