Electric Generator

Electric Generator
We know that the motors get their power from the
batteries that are inside the RCX. The motor
converts electrical power into rotational motion.
But, is it possible to go the other way. Can you
create electrical power from rotational motion?

Electric Generator
YES! Try the following experiment. Connect two
motors together with a motor cable as shown.
Attach wheels to the axles so you can turn it.
Turn one of the wheels. Does the other one turn?

Electric Generator
The motor has become an electric generator.
Rotational motion (supplied by you) is converted
into electrical power, which is sent to the other
motor.
Research idea Have your students write a report
on how real electric generators work and what
fuels they use to create electricity.
