Working model of an electric motor for student experiments. By assembling this model, students become familiar with the components and structure of a motor. The simplicity of the model enables a transparent representation of the function of the motor. The permanent magnet can be replaced by an electromagnet, which allows the motor to be operated with both direct and alternating current. Of course, operation as a main or shunt motor is also possible! The drive shaft of the motor is equipped with a pulley.
The tools required to assemble the working model are included in the scope of delivery!

Circuits
Electrical engineering is omnipresent in the pupils' world of experience. The experiments in the case help them gain insights into the use of electricity to generate light, heat and movement. These three possible uses are reproduced in simple experiments and then transferred to the environment.
The children learn that electricity can only develop its effect when it "flows in a circle" through conductive materials - and that technically stable connections are necessary for this. The simple materials in the case in traditional connection technology make these elementary relationships transparent and manageable.
The following topics are covered:
- Open and closed circuits
- Series and parallel connection
- Conductive and non-conductive materials
- Electric current hazards
- The path of household electricity
From Batt-Man to the trembling roller coaster with the buttonhole lamp to the robot game.
- 33 stations with suitable templates
- Material for 15 groups
For experimental transformer tests.
The set at this price consists of:
- transformer core with a cross section of 38x38mm,
- primary coil (600 turns) with 230V mains cable and fuse
- secondary with six outputs from coil (2+8+8+4+2V) a total of 72 turns, max 12A.
It is possible to order coils with different number of turns (6k, 600k, 1200k, 6000k at prices from 134 to 191 eur each), a Thompson ring (15.24 eur), a welding coil (191 eur) and a metal melting coil (50 eur).
