Different Types of Induction Motor and Features

Hello, readers welcome to the new tutorial. In this post, we will learn Different Types of Induction Motor. The type of motor that operates the phenomena of electromagnetic induction to generate the flux and current in the rotating part is called an induction motor also named an asynchronous motor. There are 2 basic categories of induction motors based on rotor design first one is a wound and the second is a squirrel.

It is mostly used at the industrial level and a single-phase motor is used as a home to run heavy loads. In this post, we will discuss its different types, their features, and related parameters. So let’s get started.

Different Types of Induction Motor

• There are two main types of induction motors first one is single phase induction motor and the second is a three-phase induction motor

• .
• These two motors are further divided into many types.

Single Phase Induction Motor

• A Single-phase motor has a single-phase winding this winding is wound on the stating part of the motor and its cage winding is wound on the motor’s rotating part which is the rotor.
• When a single phase is applied to this motor then the revolving magnetic field is created.

• There are many types of single-phase induction motors.
  • Split-Phase Induction Motor
  • Shaded Pole Induction Motor
  • Capacitor Start and Capacitor Run Induction Motor
  • Capacitor Start Induction Motor

Three-Phase Induction Motor

• Three-phase motors are self-start and as we studied in a single-phase induction motor article it need capacitors to start its operation.
• Squirrel cage motors are generally used due to their rugged construction and simplest enterprise.
• The wound rotor motor needs exterior resistances to have higher initial torque.
• In our industries and households, 3-phase induction motors are used.
• This motor is further divided into 2 types first one squirrel cage and the other is wound rotor.

Let’s discuss all types with a detailed

Split-Phase Induction Motor

• This motor of single-phase resistance start motor consists of cage rotor.
• There are 2 windings wounded at the starting part of the motor one is the main and the other is called the starting.
• There is a ninety-degree angle between these two windings.
• The value of inductance for starting windings is less than the resistance value and for the main, it is the opposite resistance is less inductance is high.

 

shaded pole single-phase induction motor

• The rotor of this motor is salient and has different numbers of poles according to use. Poles are configured through copper rings that show inductive behavior.
• The poles of this motor have two portions that are not the same configured small part consists of copper rings and is considered as a shaded region.

• Its benefits is that less expensive and easy to use
• The absence of a centrifugal switch makes its construction simple
• Also, offered some disadvantages like less value of power factor.
• It also has less value of starting torque.

Capacitor Start and Capacitor Run Induction Motor

• This motor comprises of the rotor and single cage rotor.
• On the stating part, two windings are wounded main and auxiliary.
• Auxiliary windings are named starting winding.
• The angle difference between these two windings is 90 degrees.
• There are two capacitors used in this motor starting and the second one running.
• It is used for operations where a large value of starting torque is need.

Capacitor Start Induction Motor

• In this motor is capacitor is linked with the auxiliary winding to generate a large value of phase difference between the current flowing in the main winding and the auxiliary.

• Capacitor’s purpose if to start the motor after that not take part in the operation.
• It consists of 2 windings at the stator and the rotor is cage-type. Windings at stator are called main and starting or auxiliary.
• The phase difference between windings is 90 degrees.
• A capacitor is linked to starting windings in series combinations and a centrifugal switch is also used in this motor.
• Its rating lies between one twenty watts to seven-kilo watts
• It can generate the starting torque three times more than full load torque.
• For having a large value of starting current there should a high value of starting torque and the value of resistance at starting windings is low.

Applications of Induction Motor

• There is a lot of applications of induction motors. It is the most commonly used motor in our houses and industries.
• Use in drill machine
• employed in Electrical operated razors
• Used in toys, robots
• The juicer machine has an induction motor
• EMployed in small-size fans
• The pump uses this motor.
