FIELD: electrical engineering; controlling stepping-rotor motors for high-precision positioning of optical devices such as microscope stage and the like.
SUBSTANCE: proposed method for controlling DC drive includes electric motor connection to power supply by means of switching unit controlled by pulse-width modulated signal generated by feedback computing device using results of comparing actuating device sensor data and target data, power-supply pulse-to-pulse interval being longer than braking time till complete stop of motor.
EFFECT: enhanced precision of control attained by simple means.
