Alright so today on Repairs101 Ė Iíve got this science kit from 1965 Ė still in its original box Ė that Iím going to open and assemble and use to explain all the different components of an electric motor and how one works.
Iím unboxing a fifty year old kidsí toy that most kids would find pointless and boring because understanding how an electric motor works will unlock the secret of how literally millions of different machines work; machines that you use and ride on everyday.
This invention is widely used because of its versatility Ė it can be made small enough to drive the hands on the tiniest wristwatches and big and heavy enough to drive the wheels on the heaviest of heavy equipment.
The coils are all wound clockwise so that the magnetic fields are consistent.
The motor exploits the concept of magnetic attraction and repulsion and the forces of nature are put to work using rotating and stationary electro-magnets.
As the rotor spins, each commutator comes in and out of contact with the power circuit through the brushes.
The stator is an electro-magnet that is energized at the same time as the rotor.
As for all you thinking girls and boys who are going to go on to become engineers and industrial designers Ė remember this machine. It runs completely clean. Donít forget.
Alright, thanks for watching and donít forget to subscribe!
