The COM4LAB course “Asynchronous machines” is the first course on the fascinating world of electric loads. The operating behaviour of asynchronous machines is explained on a physical-mechanical level and also examined by recording characteristic curves using an integrated machine test system. Connection techniques for asynchronous machines, changing the direction of rotation and speed control are worked out in practice using a large number of experiments. The course consists of 10 chapters.
Total duration: Up to 6 hours
Target audience
The course can be used to support the training process for the following professions, among others:
- Electrical systems fitter
- Electronics technician for machine and drive technology
Learning objectives
The learners should:
- be able to recognise the basic physical principles of asynchronous machines and
- their machine characteristics.
Topics
The course will cover the following topics:
- Setup
- Function
- Slip
- Star-delta Starting
- Direction of rotation
- Torque-speed characteristic curve
- Tilting moment
- Power curve
- Speed control
- Control characteristic
Previous knowledge
Learners need basic knowledge of direct and alternating current technology as well as basic knowledge of electromagnetism in order to successfully complete the course. They should be familiar with the measurement of electrical quantities. For this purpose, the use of simple formulae is a prerequisite.
