This combined teaching set provides a complete solution to teaching analog and digital motor control. The comprehensive teaching set includes a DC motor control module, command potentiometer, PID controller module, input/output interface module, and PDF format curriculum manuals. A power supply unit and connection leads are also provided.

The DC motor module is connected to a computer via a high-speed digital interface. Software is then used to provide a rich graphical environment to study the performance of speed and position control systems using both analog and digital transducers. The mechanical unit is fitted with incremental and absolute (Gray) encoders. The motor can be controlled via a proportional voltage input or via a Pulse-Width Modulated (PWM) input. Conventional analog tacho generator and potentiometer feedback is also provided, interfaced to the computer via analog to digital converters.
