In the "Electrical Machines" laboratory (EMS), students gain an understanding of how to operate electrical machines as part of their Hauptstudium. During guided and open-ended experiments, they combine everything they have learned about electrical engineering and mechanics to date. Here, students determine operating parameters, conceptualize equivalent circuits and interpret measured values in order to analyze properties and performance characteristics of DC motors, asynchronous induction motors and synchronous motors.
For this laboratory, students are required to have profound knowledge in the fundamentals of electrical engineering and mechanics, which are part of their Grundstudium.
The laboratory's energy supply is based on an IT grid with insulation monitoring. Electrical power converters and variable-frequency drives secure the power supply of the following machines:
Testing stations:
DC motors
Asynchronous induction motors
Synchronous motors (salient and non-salient pole types)
Detailed descriptions and documents related to the laboratory experiments can be found in the "Electrical Machines Practical Course" (Praktikum Elektrische Maschinen) on the Moodle platform.
ECTS: This course rewards students with 7 Credit Points
Course syllabus:
Theory of DC motors (the standard machine's structure and functioning, equations for voltage, torque and rotational speed, controlling methods, types of DC motors)
Foundations of rotating electric machines (rotating field and strand types) Theory of asynchronous induction motors (the slip ring motor's structure and functioning, asynchronous characteristics, equivalent circuits and vector diagrams, the torque's characteristics curve, the electricity's locus curve, controlling methods, squirrel-cage rotors) Theory of synchronous motors (the non-salient pole's structure and functioning, synchronous characteristics, equivalent circuits and vector diagrams, the torque's characteristics curve, isolated and grid operation, effective and idle power, special types)
