An induction motor is an electric motor that uses alternating current (AC) to produce rotational motion. It consists of a stator, which is a stationary outer shell, and a rotor, which is a rotating inner shell. The stator has a winding of conductors that carries alternating current, which creates a magnetic field. The rotor has a winding of conductors or a cage of conductive material that is short-circuited at the ends.
When the stator winding is energized with AC current, it creates a rotating magnetic field. This field interacts with the magnetic field of the rotor, forcing it to rotate in the stator field's direction. The rotor follows the stator field at a slightly slower speed, called the slip speed, due to losses in the rotor circuit.
Induction motors are widely used in a variety of applications because of their simplicity, reliability, and low cost. Appliances for the home commonly use them, such as washing machines and refrigerators, and in industrial applications, such as pumps, fans, and conveyors. They are also used in electric vehicles and wind turbines.
Many companies provide induction motors. One of them is Bharat Bijlee , which sells various types of electric motor ,one of them It also sells induction motors.
Types of induction motors
- Single-Phase Induction Motors: These motors have a single winding on the stator and operate on single-phase AC power. They are used in small appliances and tools, such as fans and pumps.
- Three-Phase Induction Motors: These motors have three windings on the stator and operate on three-phase AC power. They are more common and are used in a wide range of applications, including pumps, fans, conveyors, and other industrial equipment.
- Squirrel Cage Induction Motors: These motors have a cage-like rotor made of copper or aluminum bars that are short-circuited at the ends. They are widely used in industrial applications because of their rugged construction and simple design.
- Slip Ring Induction Motors: These motors have a winding on the rotor in addition to the stator winding. They are used in applications where the speed of the motor needs to be controlled, such as in cranes and hoists.
- Synchronous Motors: These motors have a rotor with a winding that is magnetically excited by a DC current. They operate at a constant speed and are used in applications where precise speed control is required, such as in clocks and turntables.
- Self-Excited Induction Motors: These motors have a rotor winding that is excited by the stator winding. They are used in applications where the speed of the motor needs to be adjusted, such as in pumps and compressors.
- Doubly-Fed Induction Motors: These motors have a rotor winding that is fed by a separate AC power source, in addition to the stator winding. They are used in applications where the speed of the motor needs to be controlled, such as in wind turbines and electrical vehicles.

Are you sure you’re well verse with the term?
Well, I can guarantee that you don’t.
‘Cache’ is often heard or may be an overheard term in the digital world.
Though, we often get to read it along the dedicated server specifications, but only a few know what its role is.Before describing its operation, it is important to know that Cache is often used in many protocols and technologies.
The prime aim of Cache is to communicate between two or more machines faster.
That means it avoids unnecessary recurrence action and data exchange.
In the new order of world affairs, events have taken a different shape altogether.
To keep people’s spirits high and bring them together at a seamless platform is where the virtual events shine bright.Virtual events are online events often featuring webinar and webcasts, ranging from small meet-ups to large scale conferences.
Virtual events are the best way to reach out to a large-scaled audience or even create buzz for prospective attendees.
