Freie Universität Bozen

Laboratory for Electric Drives and Fluid Machines


This laboratory is used by the staff researching Fluid machines and Electrical Drives. In the Fluid Machines Lab, we perform tests on internal combustion engines. A brake bench is used to control the rotational speed of engines and to measure the output torque. A specific acquisition system is used to obtain the most important engine performance parameters: measurement instruments allow to evaluate – for example – engine fuel consumption; temperature in significant points of the engine; and pollutants at the exhaust.

The lab is also equipped with a small workbench for simple mechanical operations on machinery. As far as electrical machines and drives are concerned, lab activities include the study and design of electrical machines and experimental validation of performance by developing suitable drive control. An important feature of the electrical machines and drives laboratory is the synergy between our university and motor and control designers. Moreover, our students have the opportunity to develop small-scale projects with Arduino.
