The experiments are carried out using the STE plug-in system Electricity/Electronics.


  • Recognition of basic physical principles
  • Implementation of electrical circuits according to circuit diagrams

Self-assembly of electrical machines is particularly effective for building understanding of how motors and generators work. For example, the process of commutation and the forces involved in it can be grasped intuitively and is especially clear when machines are rotating slowly.

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.

For more advanced work, the following sets are recommended:

  • E2.1.1.1 Electromagnetism & induction
  • E2.1.1.2 Three-phase transformers
  • E2.1.1.3 Three-phase rectification


  • Magnetic field of a stator
  • Magnetic fields of rotors
  • How rotors respond in the magnetic field of a stator
  • Electromagnetic induction using a bar magnet and a coil
  • Dynamos
  • Universal generators – functioning principle/operating properties
  • Power station generators
  • AC/DC generators with electromagnetic stator
  • DC motors - functioning principle/power consumption
  • DC motors with electromagnetic stator
  • Shunt-wound universal motors
  • Series-wound universal motors - functioning principle/power consumption
  • Synchronous motors
  • Electronic motors
