An electric motor is a device which runs by converting the electrical energy to mechanical energy. The magnetic fields in the motors help to generate power and motion. The electric motors are categorized under two major types: Direct Current (DC) motors and Alternating Current (AC) motors. They have different methods of mechanism. Both of them have separate uses and functions. Two types of DC motors are available: one with brushes and the other one brushless. AC motors can be of single phase, two phase and three phase.

DC electric motors came first in the market. They are not good enough for generating power over a long span of time. The ring in the brush DC motors help to conduct the electricity to form a magnetic force for increasing the power of the motor. In brushless ones the magnetic drive helps to enhance the power. DC motors are generally used in the home appliances. AC electric motors are normally used in the industries. The single phase AC motors are used in the machines which require high force and power to start. The motor supplies the power according to the requirement of the machine.
