How does an induction motor works?
In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. Induction motors are referred to as ‘asynchronous motors’ because they operate at a speed less than their synchronous speed.
What type of motor is an induction motor?
The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding.
How does a 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.
What is the cost of induction motor?

Do induction motors have magnets?
Nikola Tesla conceived the induction motor in 1883. It’s fundamentally the same basic stator design as the permanent motor, but without the permanent magnets. Its basic operating principle is that the magnetic field generated in the stator creates an opposing current in the rotor bars.
Why it is called induction motor?
This type of engine is also known as an induction motor. The asynchronous motor is based on the currents induced in the rotor from the rotating magnetic field of the stator. That’s why it’s called an induction machine.
What is an induction motor and how does it work?
What is an Induction Motor? An induction motor (also known as an asynchronous motor) is a commonly used AC electric motor. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding.
What are the types of rotors used in induction motor?
There are two types of the rotor which are used in an induction motor. The first one is the Wound rotor and the other is a squirrel cage rotor. This rotor is known as squirrel cage because its construction is like a squirrel. Its shape is similar to the cylinder which has laminated slots as a conductor.
What is a slip ring induction motor?
In wound rotor or slip ring induction motor, the insulated windings are wound on the rotor in the same manner as on the stator. This rotor winding is uniformly distributed and generally connected in STAR. The three leads from this STAR connection is taken out through slip ring.
What are the types of 3 phase induction motor?
Types of 3 Phase Induction Motor: A three phase induction motor (IM) has two major components, Stator and Rotor. Stator is the stationary part whereas Rotor is rotating part. Load is coupled to the rotor shaft of the motor. Three phase armature winding is wound on the stator.
