Direct current or DC electric motors work for situations
where speed needs to be controlled. DC motors have a stable
and continuous current. DC motors were the first and
earliest motors used. They were found, however, to not be
as good at producing power over long lengths. Electric
companies found using DC motors to generate electric did
not work because the power was lost as the electric was
transmitted. Brush DC motors use rings that conduct the
current and form the magnetic drive that powers the rotor.
Brushless DC motors use a switch to produce the magnetic
drive that powers the rotor. Direct current motors are
often found in appliances around the home.
Alternating current or AC electric motors are used
differently based on what type of AC motor it is. Single
phase AC motors are known as general purpose motors. They
work well in many different situations. These AC motors
work great for systems that are hard to start because they
need a lot of power up front. Three phase, also called
polyphase, AC motors are usually found in industrial
settings. These motors also have high starting power built
transmit lower levels of overall power. AC power gets its
name from the fact that it alternates in power. The amount
of power given off by an AC motor is determined by the
amount of power needed to operate the system
