AC and DC motors serve as the power sources for an incredible
amount of gadgets and gizmos that we use today. Everything
from your refrigerator to your your bedroom fan uses electric
motors as their power source. In many of these cases,
electric motors are the only practical power
source. For example, what if, instead of an electric motor,
your bedroom fan was powered by a gas motor? Well, for
starters, it would be expensive (and a real pain) to keep the
motor filled with gas. More importantly, the motor would
produce Carbon Monoxide which would build up in your house and
could poison you! The same is true for things like
refrigerators and hair dryers. Another added benefit of
electric motors is that they tend to be quieter (it would be a
real pain listening to a gas powered refrigerator at 3
A.M.).
AC and DC motors are continually being improved to serve in more
diverse areas of life all the time. For example, humans are
beginning to figure out how to make electric powered
vehicles. While these vehicles are still a new idea and need
to be refined, the idea could wind up being a big plus for the
environment due to less air pollution.
If you look around, it won't take long to find something that is power by either an AC or DC motor. Below are a few things that use such engines.
