What are DC Electric Motors?

Electric motors are one of the most common forms of motor in the modern world. They are literally everywhere. The smallest Motor can be found in a Wristwatch and the largest in a Water Pump. It works on the principle of ‘Conversion of Electric energy to Mechanical energy’. Just about every household or industrial appliance relies on AC or DC electric motors to move or operate. Cars, for example are bursting with DC electric motors that are used to operate electric radio antennas, windshield wipers, heater and radiator fans, power windows and mirrors and power seats. In fact, power seats in a vehicle contain up to seven electrical motors each.

DC motors runs on DC electric power as oppose to "AC" electric motors that run off an alternating current.DC stands for ‘Direct Current’. DC electric Motors are made up of six components: a rotor or armature, a commutator, an axle, brushes, a field magnet, and a direct current power supply. These Motors are compiled in the following way: the axle holds the commutator and the armature which is a set of electromagnets. Both ends of the wires supplied for each magnetic pole are soldered to a terminal. Each of these motors three terminals are wired to a plate on the commutator. The last essential element of DC electric motors is a field magnet. The role of a field magnet is to create a magnetic field for the armature to react to.
