What are the main parts of 3 phase induction motor?

What are the major parts of induction motor?

Parts of Induction Motors

  • Stator. The stator is the stationary portion of the motor and delivers a rotating magnetic field to interact with the rotor. …
  • Rotor. The rotor is the central component of the motor, and is fixed to the shaft. …
  • Shaft. The motor shaft is fixed within the rotor, and rotates with it. …
  • Bearings. …
  • Casing.

What are the parts of a 3-phase motor?

Three-phase motors are a type of AC motor that is a specific example of a polyphase motor. These motors can be either an induction motor (also called an asynchronous motor) or a synchronous motor. The motors consist of three main components – the stator, the rotor, and the enclosure.

What are the 2 major components of a three-phase motor?

A 3-phase induction motor includes two essential components namely the stator & the rotor. In this motor, the stationary part is the stator whereas the rotating part is the rotor. In this motor, the load is connected to the shaft. Three-phase armature winding can be wound over the stator.

How does a 3 phase induction motor work?

The working of the three-phase induction motor is based on the principle of electromagnetic induction. When three-phase stator winding of an induction motor is energized from a 3 phase supply, a rotating magnetic field is set up which rotates around the stator at synchronous speed (Ns).

What are the two main parts of the three-phase squirrel cage induction?

A Squirrel Cage Induction Motor is the most common 3 phase motor found in a mill or plant. It is both rugged and simple in design, making it both economical and reliable. The SCIM has 2 basic components, a stator (the stationary component) and a rotor (the rotating element).

What is slip in induction motor?

“Slip” in an AC induction motor is defined as:

As the speed of the rotor drops below the stator speed, or synchronous speed, the rotation rate of the magnetic field in the rotor increases, inducing more current in the rotor’s windings and creating more torque. Slip is required to produce torque.

What is 3phase induction motor PDF?

Introduction: The three phase induction motors are simple in construction, rugged, low cost and easy to maintain. They run at a constant speed from no-load to the full load. Therefore, these motors are frequently used in industry. Induction Motor Parts.

What are the parts of motor?

A simple motor has the following parts:

  • A power supply – mostly DC for a simple motor.
  • Field Magnet – could be a permanent magnet or an electromagnet.
  • An Armature or rotor.
  • Commutator.
  • Brushes.
  • Axle.
