Electric
motors, one of the most important inventions the world has ever seen. The technology in them is used in cars, boats,
planes, ceiling fans, and even blenders! By turning electricity into motion, it
unlocked a world of possibilities.
In 1834,
Thomas Davenport invented the first usable electric motor. Although it was not
the first motor, it was the first one that could benefit humankind. With his
first motor, he ran a model trolley around a circular track. Although the full-sized
trolley would not be invented until after his death, this miniature was
revolutionary, as it was one of the first uses of electricity. Once the full-sized
trolley was invented, it would become the first mode of public transportation,
helping people get to work and paving the way for cars and busses. 
Another early engineer, Hippolyte Pixii discovered that by running the motor backwards, he was
able to generate sparks. He used this newfound knowledge to invent generators.
Without this, we would not heave electricity in our homes, as prior to this,
the only way to use electricity was through batteries. To use batteries to
power homes proved inefficient, and this invention is essential for modern
life.
Motors
are relatively simple pieces of machinery. They are powered by two forces-
electricity and magnetism. When electricity flows through a coil of wire, it
creates an electromagnet. When another current is sent down another coil, positioned
90 degrees from the first, it creates a second electromagnet within the pull of
the first. The attraction causes the wires to pull on each other, creating
movement.
Motors
are used in hundreds, if not thousands of modern inventions. Some examples are:
· Engines
· Generators/Dynamos
Food processors
Food processors
· Elevators
· Fans
· DVD/CD players
· Steel Mills
· Conveyor
belts
· And many
more
