Question: What are the applications of three phase induction motor?

They are used for loads that requires speed control. Typical applications of wound rotor or slip ring induction motors are crushers, plunger pumps, cranes & hoists, elevators, compressors and conveyors.

What are the applications of induction motor?

The rotor of an induction motor can be a squirrel cage rotor or wound type rotor. Used in different applications, induction motors are also called Asynchronous Motors.

Some of the applications are mentioned below:

  • Pumps.
  • Compressors.
  • Small fans.
  • Mixers.
  • Toys.
  • High speed vacuum cleaners.
  • Electric shavers.
  • Drilling machines.

What are three phase motors used for?

Asynchronous three-phase squirrel-cage or wound rotor motors are the most common in industry. This is mainly due to their simple design, easy operation and the ability to achieve much higher power outputs than single-phase motors. They are used in compressors, lathes, milling machines, and many other devices.

What are the advantages of 3 phase induction motor?

Advantages of Three Phase Induction Motor

It requires less maintenance. It has high efficiency and good power factor. It is less expensive. It has self-starting torque.

What is a three-phase induction motor?

Three Phase AC Induction Motor. The three-phase AC induction motor is a rotating electric machine that is designed to operate on a three-phase supply. This 3 phase motor is also called as an asynchronous motor. … The principle of operation of this motor is based on the production of a rotating magnetic field.

Why is an induction motor used for most domestic applications?

Induction motors are used in industrial and domestic appliances because these are rugged in construction requiring hardly any maintenance, that they are comparatively cheap, and require supply only to the stator.

What are the advantages of three-phase system?

A three-phase circuit provides greater power density than a one-phase circuit at the same amperage, keeping wiring size and costs lower. In addition, three-phase power makes it easier to balance loads, minimizing harmonic currents and the need for large neutral wires.

What are the advantages and disadvantages of 3 phase induction motor?

3 phase induction motors have poor starting torque and high have in rush currents. Therefore these motors are not widely used for applications which require high starting torques like traction systems. Squirrel cage induction motor have poor starting torque.

What is the most important advantages of the induction motor?

The most important advantage of an induction motor is that its construction is quite simple in nature. The construction of the Stator is similar in both Synchronous motors as well as induction motors. However, a slip ring is required to feed DC Supply to the Rotor in the case of a Synchronous Generator.

What are advantages of induction motor?

Advantages of an induction motor (IM):

  • The working of an induction motor is very simple. …
  • It is very cheap in cost to compare the other motors.
  • It is a highly efficient motor. …
  • The brushes are not used in an induction motor. …
  • The maintenance of IM is very less compared to the DC motor and synchronous motor.
