A simple method allowing operation of a step motor in the fractional step mode is considered. A scheme is suggested of a power supply constructed on the basis of the AT90S2313 microcontroller which supports the performance of the step motor in the considered mode. A control program for the microcontroller is described. The presented results are supposed to be successfully used to construct the devices with a high positioning accuracy of separate units and elements.
