COM4LAB: Synchronous Machines

The COM4LAB course entitled “Synchronous Machines” is the second course to the fascinating world of electrical machines. The performance of the synchronous machines, the speed measurement and the speed adjustment are examined. The design, the principle of operation and the performance of the stepper motor are practically devised using a number of experiments. The course comprises 9 chapters.

Total duration: Up to 9 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 synchronous machines and
• be able to recognise the design, the principle of operation and different operating modes of the stepper motors.

Topics

The course covers the following topics:

Synchronous machines

• terminal
• rotational direction
• stepper mode

  star connection – delta connection

• speed measurement
• speed adjustment with frequency converter

Stepper motor

• design
• principle of operation
• rotational direction
• stepper mode

  full-step mode – half-step mode

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.
