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.
