The COM4LAB course entitled “Asynchronous Machines” is the first course to the fascinating world of electrical machines. The performance of the asynchronous machines is explained on a physical-mechanical level as well as examined by recording characteristics using an integrated machine test system. Terminal connections, changing of rotational direction and speed control are practically devised using a number of experiments. The course comprises 10 chapters.

Total duration: Up to 10 hours

Target audience

Among others, the course can be used to support the training process for the following professions:

  • electrical system fitter
  • electronics technician for machine and drive technology

Learning objectives

The students are to:

  • be able to recognise the basic physical principles of asynchronous machines and
  • be able to record the characteristics of asynchronous machines.


The course covers the following topics:

  • design
  • function
  • slip
  • star-delta start
  • rotational direction
  • torque-speed characteristic
  • breakdown torque
  • power characteristic
  • speed control
  • control characteristic

Previous knowledge

The students need basic knowledge in the areas of DC and AC technology as well as basic knowledge of electromagnetism in order to be able to complete the course successfully. They should be familiar with the measurement of electrical quantities. In addition, dealing with simple formulas is required.
