FIELD: electricity.
SUBSTANCE: device comprises DC motor, unit of start-up resistors comprising N controlled stages, current sensor, amplifier of mismatch signal, device of access-storage, pulse generator, setter of reference voltage and control unit arranged according to multizone principle, number of zones of which equals to number of controlled stages of start-up resistors unit, each zone of control unit is equipped with generator of saw-like voltage, comparator, pulse amplifier, semiconductor switch.
EFFECT: reduced pulsations of anchor current, increased accuracy of control and functional reliability of system due to application of multizone modulation for pulse control of electric motor current.
