Electric motors and generators are in countless devices, appliances, and vehicles we use every day. They are an essential technology in our modern world. Thames and Kosmos Motors Generators With this kit, you can conduct 25 experiments to learn how an electric motor converts electricity into motion, and how an electric generator does just the opposite, converting motion into electricity. The electric motor is made of transparent plastic to show how the inside components work. Set up the motor to run on battery power and learn how a motor works. Then reconfigure the device to work in reverse as a hand-crank electric generator.
