What are the applications of induction motor?

What are the applications of 3 phase induction motor?

The squirrel cage induction motors are used in residential as well as industrial applications especially where the speed control of motors is not needed such as:

  • Pumps and submersible.
  • Pressing machine.
  • Lathe machine.
  • Grinding machine.
  • Conveyor.
  • Flour mills.
  • Compressor.
  • And other low mechanical power applications.

How many types of induction motors are there?

There are mainly two types of induction motor. This classification is based on what power supply induction motors are fed with. Single-phase induction motors and three-phase induction motors are the two main types of induction motors.

What are the advantages of induction motor?

Induction Motor Advantages:

  • Induction motors are simple and rugged in construction. …
  • Induction motors are cheaper in cost due to the absence of brushes, commutators, and slip rings.
  • They are maintenance free motors unlike dc motors and synchronous motors due to the absence of brushes, commutators and slip rings.

What are the advantages of 3 phase induction motor?

Unlike synchronous motors, a 3 phase induction motor has a high starting torque, good speed regulation and reasonable overload capacity. An induction motor is a highly efficient machine with full load efficiency varying from 85 to 97 percent.

What are two types of induction motor?

  • Two types of Induction Motors.
  • Single phase induction motor. The single-phase induction motor does not self-start. …
  • Applications of Single-phase Induction Motors. The single-phase induction motors are used in low power applications. …
  • Three-Phase Induction Motor:

What are the types of induction motors?

Types of Induction Motors

  • Split Phase Induction Motor.
  • Capacitor Start Induction Motor.
  • Capacitor Start and Capacitor Run Induction Motor.
  • Shaded Pole Induction Motor.

What are the two types of induction?

Induction motors are classified into two types namely single phase induction motor and three-phase induction motor. As their name suggests, a 1-phase induction motor is connected to a single-phase AC power supply whereas the 3-phase induction motor can be connected to a three-phase AC power supply.

How does an induction motor start?

A three-phase Induction Motor is Self Starting. When the supply is connected to the stator of a three-phase induction motor, a rotating magnetic field is produced, and the rotor begins rotating and the induction motor starts.

Why do we use synchronous motors?

In higher power industrial sizes, the synchronous motor provides two important functions. First, it is a highly efficient means of converting AC energy to work. Second, it can operate at leading or unity power factor and thereby providing power-factor correction.

What is the principle of induction motor?

The motor which works on the principle of electromagnetic induction is known as the induction motor. 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 the main parts of an induction motor?

Parts of an Induction Motor

  • The A.C. Induction Motor has three main parts, rotor, stator and enclosure. …
  • The stator is the stationary part of the motor’s electromagnetic circuit and is made up of thin metal sheets, called laminations. …
  • Coils of insulated wire are inserted into slots of the stator core.

What is difference between induction motor and synchronous motor?

The induction motor has self-starting torque whereas the synchronous motor is not self starting. It has to be run up to synchronous speed by any means before it can be synchronized to AC supply. A synchronous motor can be operated with lagging and leading power by changing its excitation.

What are the types of single phase induction motors?

Types of single phase induction motors

  • Split-phase motor.
  • Capacitor-start motor.
  • Capacitor-start capacitor-run motor.
  • Permanent-split capacitor (PSC) motor.
  • Shaded-pole motor.
