Motors-Basics
• Motors are nothing more than converters of electricity — electric motors
are machines that convert electricity into a mechanical motion (kinetic
energy).
• A generator or dynamo does the reverse – converting kinetic energy into
electrical energy.
• Motor Basics: When you connect the Battery Leads to the battery via a
wire, the axle will spin.
• If you reverse the battery terminals the wires are connected to, the axle
will spin in the opposite direction.
Axle – this spins when connected to the
battery

SAFETY NOTE: Match voltage & amperage to make sure motor functions correctly
(hint: look on the label)

• Where do you find motors? Motors are in EVERYTHING – model cars, big
cars, washing machines, all you have to do is look.
– Take a technical device apart (with permission)
