Motor Vibration Test Rig

This was a simple and short development project we did for an aero engine manufacturer. A vibration test control rig required updating, the existing belt driven motor setup took offered poor control and accuracy and changes in speed were controlled manually introducing experimentation error. Using a high performance servo stepper motor from JVL and ActiveX controls we were able to design a simple program which allowed for fine control of the motor. The user defined motor speed profile is displayed by means of a graph with the actual speed feedback from the motor plotted in real-time also being plotted alongside.
