Principle

When electric motors with a higher performance are required, they are generally constructed with electromagnets instead of permanent magnets, as above all these can generate stronger magnetic fields. In a main circuit motor, the armature coil and the field coil are connected in series.
The experiments are so designed, that they only provide qualitative or semi-quantitative results.

Benefits

• No additional cable connections between the building blocks needed - clear arragned and quick setup
• Contact saftey due to puzzle blocks system
• Corrosion-free gold plated contacts
• Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside

Tasks

What are the characteristics of main circuit motors?

Assemble a model of an electric motor in which the permanent magnet is replaced by an electromagnet, and use it to examine which the characteristics of the motor are when the coil of the stator and the rotor are connected in series.
