What are the main parts of induction motor?

The A.C. Induction Motor has three main parts, rotor, stator and enclosure. The stator and rotor do the work and the enclosure protects the rotor and stator. STATOR CORE: The stator is the stationary part of the motor’s electromagnetic circuit and is made up of thin metal sheets, called laminations.

What are the main parts of 3 phase induction motor?

The stator of the three-phase induction motor consists of three main parts :

  • Stator frame,
  • Stator core,
  • Stator winding or field winding.

What are the two main parts of an induction motor?

Like any other electrical motor, induction motor have two main parts namely rotor and stator.

What are the main parts of a motor?

Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.

What is the basic principle of induction motor?

The motor which works on the principle of electromagnetic induction is known as the induction motor. The electromagnetic induction is the phenomenon in which the electromotive force induces across the electrical conductor when it is placed in a rotating magnetic field.

What are 3 phase induction motors used for?

Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans.

What is stator in 3 phase induction?

A three phase Induction motor mainly consists of two parts called as the Stator and the Rotor. The stator is the stationary part of the induction motor, and the rotor is the rotating part.

What is synchronous speed?

Synchronous speed is a significant parameter for the rotating magnetic field-type AC motor. It is determined by the frequency and the number of magnetic poles. Synchronous speed No = [rps, revolutions per second] f = Frequency [Hz]

What is slip in induction motor?

Slip is the differentiation between synchronous and asynchronous speed. … The difference between the synchronous speed of the electric motor magnetic field, and the shaft rotating speed is slip – measured in RPM or frequency. Slip increases with increasing load – providing a greater torque.

What is slip speed?

The speed at which the induction motor work is known as the slip speed. … The difference between the synchronous speed and the actual speed of the rotor is known as the slip speed. In other words, the slip speed shows the relative speed of the rotor concerning the speed of the field.

What is the principle of motor?

The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.

What are the three types of motors?

Basic motors have been classified into three distinct types: AC motor, DC motor, and specialized motors.

What are 3 types of motor controls?

There are mainly there are three types of motor control circuits:

  • Direct On Line Starter (DOL starter)
  • Star Delta Starter.
  • Auto Transformer Starter.

What are the types of motors?

Types of Electric Motors

  • AC Brushless Motors. AC brushless motors are some of the most popular in motion control. …
  • DC Brushed Motors. In a DC brushed motor, brush orientation on the stator determines current flow. …
  • DC Brushless Motors. …
  • Direct Drive. …
  • Linear Motors. …
  • Servo Motors. …
  • Stepper Motors.

What is advantage and disadvantage of induction motor?

A single phase induction motor, unlike a 3 phase induction motor, does not have a self starting torque. Auxiliaries are required to start a single phase motor. During light load conditions, the power factor of the motor drops to a very low value.

Why starter is used in induction motor?

The three phase induction motors are self-starting due to rotating magnetic field. But the motors show tendency to draw very high current at the time of starting. … Hence there should be a device which can limit such high starting current. Such a device which limits high starting current is called a starter.11 мая 2017 г.
