Abstract

Device for controlling operation, in particular of a washing machine and similar, comprising a direct current motor (1) acting on a rotating drum in a tank and a programmer (9) to select the various operative phases of the machine, presentinga) first comparator means (15 and 16) suitable for comparison of a current signal (V8, V8') coming from the rotor (11) of the direct current motor (1) with a reference signal (V3, V4) and for emitting an output signal;b) means (21 and 22) for delaying the said output signal for a preset time;c) second comparator means (23 and 24) suitable for comparing the outgoing signal of the means of delay (21 and 22) with a reference signal (V7), the said second comparator means (23 and 24) according to the said comparison, enabling a control unit (7) to intervene on at least a static switch (5) in series to the motor (1), the said device (13) being suitable for interrupting operation of the motor (1) in blocked rotor (11) state and/or in blocked programmer (9) state.
