Abstract
A stepping motor rotational speed regulator is designed to maintain the speed of rotation constant for changing or controlling the position of a mechanical device e.g. a printing machine. The regulator comprises a timer, a control unit and an output subsystem. The control unit is connected to a subsystem for generating step control signals ad to a timing subsystem, so as to form new time delay data for each step increment of the stepping motor shaft rotation. The metered time data is compared with the nominal time slots stored in the control unit register. The output subsystem is connected to the control unit and holds the new time delay data and generates accordingly a motor step delay pulse to be fed to a circuit used for driving the stepping motor.
