3.6 Using steam energy to generate electricity
We need a generator to generate electricity out of steam. The word
“generator” has its origins in the Latin language and means freely translated
“to bring out” or “to produce”. Though looking more exactly, energy can
not be produced, only changed from one state into a different one. So in this
sense a generator is an energy transformer.
The generator, which is used here, is a direct current generator and has a
permanent magnet.
Electricity is induced into the rotor (runner), the permanent magnet is on the
outside. The generated electricity will be rectified with a commutator and
can then be taken from the red and black connection cable.
The actual voltage depends on the rotational speed, the actual electricity
depends on the construction of the generator and the torque of the steam
engine.
