Single phase ac motor ppt

Rotor:- It is the rotating part of the induction motor. It is housed on the shaft of the induction motor . It has two ends, one is called Driving end and another is called non- Driving end . Mechanical load is connected on driving end while . AC MOTOR : INDUCTION MOTOR Most common motors in industry Advantages: .

AC motors include 3-phase and single phase types.

AC induction motors are the most widely used motors in industrial and commercial applications.

The first two are highly controllable, and usually what you would use in an application. But we quickly review the others. Three or four wires that carry the . Induction motors are used worldwide as the workhorse. DOL) starter used in three-phase IM, along with the . Among all these types of motors, a few types of motors required to be operated with certain conditions. Faults in induction motors can be categorized as follows: (a) Electrical-related faults: Faults under this classification are unbalance supply voltage or current, single phasing, under or over voltage of current, reverse phase sequence, earth fault, overloa inter-turn short-circuit fault, and crawling.


They are generally used in fans, blowers, washing machines, refrigerators, etc. After studying this unit, the student will be able to. There are two types of rotors which are employed in – phase induction motor.


Copper or aluminum bar conductors are placed in these slots and . EEE - Speed control of three phase induction motor. The single phase induction motors are made self starting by providing an additional flux by some additional means. Motor have two main parts one . Now depending upon these additional means the single phase induction motors are classified as: Split phase induction . Single phase power system is widely used as compared to three phase system for domestic purpose, commercial purpose and to some extent in industrial purpose. As the single phase system is more economical and the power requirement in most of the houses, shops, offices are small, which . Generally, there are two types of the induction motors known as single phase and three phase induction motors : 1. It is widely used when compared to the three phase motor for the industrial, . Faculty of Engineering Electrical Engineering Department.


Introduction in Graduation project. Variable speed control of single phase. Single - phase distribution is used when loads are mostly lighting and heating, with few large electric motors. A shading coil slot extends into the salient pole from the air gap and defines a . The characteristics of single phase induction motors are identical to 3-phase induction motors except that single phase induction motor has no inherent starting torque and some special ar- rangements have to be made for making it self starting.


It follows that during starting period the single phase . This rotating field is the source of the induction in the rotor and the rotor currents that ,because the rotor bars are shorte are the source of the rotorfield that interacts with the rotating field of the stator.
