Electrical devices have become the significant part of our lives and these devices are completely useless without the electric motor. All the electrical devices need an electric motor to operate and function and the domestic appliances generally have single phase electric motor that enables them to smoothly and effectively operate.

Presence of electric motors in extensive array of electrical devices found in home, offices and industries have brought several types and variant of electric motors in the market. Right from computers, fans, disk drives, to DVD use electric motors to operate and function. Depending upon the operation and functionality, electric motors are categorized into two different types, one runs on alternating electric current and the other runs on direct current. AC electric motors are further categorized into single phase electric motor and three phase electric motors. Single phase electric motor is basically found in electrical devices used in home. The most commonly find single phase electric motor is universal motor, which is called so due to the fact that it can run with DC current too. The major significance of this motor is that their rotational speed can be easily changed.
Single phase electric motor is activated via medium of switch that helps in moving the rotor of the motor and also enables to create magnetic field. The magnetic field is created after the rotor sets in motion that further enables the single phase electric motor to operate efficiently. Single phase electric motor is generally used in electrical appliances that need low horsepower level and are ideal for appliances like fans, compressors, pumps, refrigerators and drills. In single phase power distribution the AC power is distributed through a system where all the voltages of the supply vary in unison. This type of power distribution is generally used when there is heating and lighting load with few large electric motors. This type of motor does not produce a revolving magnetic field and need additional circuits for starting.
Single phase electric motor further gets bifurcated into split-phase electric motor, permanent split capacitor, wound rotor, shaded pole, two-valve motor and capacitor-start single phase electric motor. Requiring very less maintenance, all the variants of single phase electric motors offers quire effective and efficient performance. The single phase electric motors are quite economical in price compared to DC motors and have great demand in the field of electrical market due to economical price, low maintenance and superior performance. Although, Like any other electric motor, single phase electric motor too requires timely service and maintenance to ensure smooth functioning and operation.
Single-phase electric motor is greatly used across the rural areas, where there are small and uncommon loads and the cost of three-phase distribution network is high. The motor supports current flow and operates electrical energy into mechanical energy through the communications of conductors and magnetic fields. Due to the better performance and reduce cost, this type of electric motors have become significant for various domestic tools and appliances. However one thing should be taken into consideration that this type of motor must not be used with the machines that contain inflammable and corrosive gas. The use of motor with such machines requires proper engineer care and maintenance.
