COM4LAB: Synchronous Machines

The COM4LAB course “Synchronous machines” is the second course on the fascinating world of electric loads. 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 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 synchronous machines and
• recognise the setup, mode of operation and different operating modes of stepper motors.

Topics

The course will cover the following topics:

Synchronous machine

• terminal
• rotational direction
• stepper mode

  star connection - delta connection

• speed measurement
• speed control with frequency inverter

Stepper motor

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

  full-step mode - half-step mode

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.
