More Information
Summary:The device is used in robotics, in digital-program control devices, etc. It may be used in various types of step motors and needs no complicated preliminary adjustment or readjustment in case changes, thus overcoming the resonance. The device consists of a clock generator (1), connected through a logical bloc (2) with a switch (3), which is connected through a current sensor (4) with a step motor (5). The current sensor is connected with a current regulator (6) and a bloc tracking the pulsations of the phase currents (7), connected to a comparison bloc (8). The latter is connected through a bloc, setting the average value of the phase currents (9), to the current regulator (6), which is connected with a second input of the comparison bloc (8).
