In their capacity as electromagnetic energy converters, we encounter electrical machines in our daily environment wherever electrical energy is to be converted into kinetic energy or vice versa.

For example, in production technology, railroads, electromobility, conservative and regenerative energy generation, in household appliances and hand tools as well as in goods logistics.

In other words, everywhere and at all times. Without electrical machines, a technological world as we know it would be inconceivable.

In the Electrical Machines module, students learn about the structure, mode of operation, operating behavior and special features of the most important basic types of electrical machines: The direct current, three-phase synchronous and three-phase asynchronous machines. The focus is on their electromagnetic mode of operation.

This will give you a sound technological overview of the entire range of electrical machines, from motor microdrives to power plant generators, and by the end of the module you will be able to name the advantages and disadvantages of the different machine concepts and answer fundamental questions about operating behavior analytically, both qualitatively and mathematically.

1. Introduction, basics and terms
2. Design, mode of operation and operating behavior of direct current machines
3. Design, mode of operation and operating behavior of three-phase synchronous machines
4. Design, mode of operation and operating behavior of three-phase asynchronous machines

Parallel to the lectures, a practical course with experiments on the operating behavior of direct current, three-phase asynchronous and three-phase synchronous machines.

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• oral exam or
• Written examination

• Field work / Experimental work

Students at Osnabrück University of Applied Sciences who have successfully completed this module are able to

• explain the structure and design features of the various machine types,
• explain the electromagnetic operating principle of the various machine types,
• derive the operating behavior from the electromagnetic operating principle and describe it using an analytical equation model.
• Perform basic practical tests on electrical machines. They are proficient in the analytical and graphical evaluation of measurement protocols and can present the test results in a technically sound manner and with current visualization media in a manner appropriate to the target group.

After completing the module, students will also have acquired the ability to

• transfer the electromagnetic operating principle of electromagnetic energy converters into analytical calculation methods for investigating various operating states.
• Investigate detailed questions on specific operating points of the machines by calculation and determine operating parameters.
• Use a toolbox for the independent processing of drive technology issues in the context of specific questions of energy technology and mechatronics,
• Compare the application limits and potential of different machine types in order to critically examine their suitability for specific drive tasks,
• Recognize the need to integrate electric machines into electric drive systems.

After successfully completing the module, students will be able to

• assess the suitability of different machine types for different drive types,
• assess questions regarding the sustainability of different electric drives for specific drive tasks,
• classify and critically reflect on common marketing terms and statements about electric drives,
• technically classify new drive concepts in the context of the energy transition process and electromobility and
• scrutinize social statements and assessments.
