E 2.1.3.3 Modele szkoleniowe maszyn niskiego napięcia
Opis
The experiments use components from the electrical machine teaching models system and utilise safety extra-low voltage. All machines are mounted on a base unit which is set up vertically in a training panel frame.
Objectives
- Recognising basic physical principles
- Recording machine characteristics
- Introduction to drive technology
- Use of simple tools (spanners, oil cans etc.)
The equipment set is complete and contains all available components for the electrical machine teaching models using safety extra-low voltage. This allows all the experiments on electrical machines, including the modern high-efficiency machines, to be carried out.
The equipment set incorporates student experiments which can be carried out in a laboratory safely using safety extra-low voltage. Experiment instructions are contained in a manual in either printed or digital form.
The target group is made up of students in general or vocational education. The experiments are designed as an introduction at a simple level of understanding.
The knowledge gained from these experiments can be directly applied to the area of industrial machines. The electrical machine teaching models for safety extra-low voltage are therefore the ideal preparation for experimenting with commercial industrial machines.
