The experiments are carried out using the multimedia training system COM3LAB.


  • Recognising basic physical principles
  • Recording machine characteristics
  • Introduction to drive technology

The equipment set includes the COM3LAB courses, Electrical machines I and Closed-loop control. This allows important experiments to be conducted in the field of electrical drives. The operating response of electrical machines is investigated in terms of physics and mechanics and by means of speed-torque characteristics. The experiments explore how electrical machines are connected, as well as reversal of direction and adjustment of speed, plus wiring of the terminal board. The closed-loop control course investigates the fundamentals of variable speed drives. The characteristic parameters for control loops are measured and the design of closed control loops is shown experimentally.


  • Compact, highly integrated machine course
  • Integrated machine test system
  • Extensive charting of technical control loops using DDC controllers

The equipment set allows students to experiment themselves in a lab equipped with PCs using safety extra-low voltage, which presents no hazard. It is also suitable for demonstration experiments by teachers. Multimedia software explains and monitors how the experiments are carried out.

The target group is made up of commercial apprentices and students of electrical machine technology. The course offers introductory experiments at a simple level and more advanced topics for undergraduate education.

The speed control of a commercially available shunt-wound machine rated at 300 W is investigated as part of a project lesson. It is necessary to use the digital controller from the COM3LAB course Control technology II, in order to configure and optimise this for the industrial motor.
