Maxon DC motor control by MF624 1/O card

Abstract

The article describes principles and shows examples of driving small Maxon DC motors using the multifunction I/O card MF624 from Humusoft. For speed control, one of Pulse-Width Modulation (PWM) unit installed on this card is used. Analog input and encoder input are used for measuring of motor speed and motor position. For educational and test purpose a small board connecting all parts (driving and measure motor, user inputs and outputs) to I/O card was developed and realized. For card control we use programming tools Visual Basic .NET and the Matlab software. Examples demonstrating the basic electric motor control and regulation task were developed for both of these software environments.
