subject: Important Things You Should Know About Single Phase Electric Motor [print this page] Electric motor is must and constitute an important part of each and every home, office or organization. They have number of valuable advantages which has contributed a lot in its growing popularity. Electric motor serves as the backbone of both large and small industries.
It is basically a device widely used for generating electricity by applying the concept of electromagnetism. In the process of electromagnetism, electricity and magnets are used to produce motion. Electric motor with the use of electricity produces a mechanical output. Thus, they are used to move objects that results in the smooth functioning of the machines. They are popularly categorized in to Single Phase Motor and Three Phase Motor.
Single phase motor is used in number of household applications. They are mostly found in number of electrical devices used in homes such as blowers, pumps, industrial fans, machine tools, household appliances, power tools, disk drivers, electrical appliances and many others. Universal motor is one of the most used and the most popular type of single phase motor. Its rotational speed can be easily changed and also it runs on both AC and DC current.
Single Phase Motors run from a power source with a singular distribution of alternating current electric power. They are employed in number of useful application. Single phase motors are highly durable as they can last a lifetime with very minimal maintenance. They are commonly used in instruments such as mechanical clocks, washing machines, and generators.
These motors are generally used for low power applications where it would be inefficient to use more high powered mechanisms. It is ideal for appliances like fans, compressors, pumps, refrigerators, drills and other household appliances. Rotor is one of the most important parts of the single phase motor. Rotor plays a key role in its operation by creating magnetic field in the circuit. It does not produce a revolving magnetic field and need additional circuits for starting.
The magnetic field is created after the rotor sets in motion that further enables it to operate efficiently. They are further sub categorized into split-phase electric motor, permanent split capacitor, wound rotor, shaded pole, two-valve and capacitor-start single phase electric motor.
They come with easy installation and maintenance process. Because of their effective and efficient performance, they require very less maintenance. They are comparatively very economical and also deliver superior performance. However, proper and timely service and maintenance is must in order to ensure better performance for and smooth functioning for longer time period.
