E 2.5.2.2 Przerywacz napędu DC z silnikiem DC
Opis
The experiments are carried out using training panels in panel frames along with a DC machine of industrial design.
Objectives
- Protective measures and electrical safety
- Experiment set-up and wiring according to a circuit diagram
- Setting up industrial commutator machines and putting them into operation
- Use of computer-assisted measurement interfaces
This equipment set allows you to set up a modern drive system in order to adjust the speed. The power electronics is implemented in the form of circuits using modular, discrete components. The load used is a DC machine operating without a load. The chopper allows for the speed to be set by limiting trigger angle and for the direction of rotation to be reversed. The trigger response of thyristors to pulse and burst control is investigated along with the resulting effects on the effects on the running characteristics of the machine.
The equipment set is suitable both for student experiments in a lab using low voltage (400 V three-phase) and on a mobile trolley for demonstrations by teachers in a classroom. The experiment procedures are contained in a printed manual.
The target group is made up of commercial apprentices and students of electrical machine construction. The course offers experiments at an intermediate level and also allows for the necessary insight into machine behaviour for scientific interpretation at undergraduate level.
Topics
- Set-up of an H-bridge
