The Y163 is a 1A/5V Stepper Motor with 1.8° stepping angle, 5R resistance, 9.5mH inductance. This stepper motor requires external drivers to control them, with components including a power supply, logic sequencer and switching components. In recent years circuit integration has enabled these to be included in a single unit and control can now be fully programmable using digital signal processors. Simon Hunt of Astrosyn International Technology outlines the fundamentals of driving stepper motors.
