In our "Electrical Drive Technology" laboratory, complex electrical drives systems are analyzed and tested. These drives consist of various motor types and their corresponding electrical power converters. They are regulated with the help of microcomputers. For simple applications, the drives can be controlled via computer programs. For complex automation tasks, however, PLC/CNC controllers are utilized. Because of this, experience with high-performance electronics, control engineering as well as knowledge of structure and operation of electrical devices is required for participation in this laboratory.
The practical laboratory exercises include the operation and parameterization, with focus on providing our students with first-hand experience. Our experiment instruction manuals are supplemented primarily by the manufacturers' operating manuals and technical documentation. We expect our students to be able to take the initiative and work their way into new topics.
Equipment
The laboratory's energy supply is based on an IT grid with insulation monitoring. Electric power converters and variable-frequency drives supply the following devices with power:
Testing stations:
- DC motors
- Three-phase asynchronous motors
- Synchronous motors (salient and non-salient motors)
Measurement stations:
- Performance analyzers
- Torque-speed measuring stations
