Induction Motors: Construction, Principle of Operation, Power and Torque Calculations, Characteristics and Speed Control June
The construction of the induction motor is explained below in detail. Construction of Stator. The stator is built up of highgrade alloy steel
It is because of the low cost, simple and rugged construction of the motor. Moreover, it has good operating characteristics with an efficiency as high as 90%. An induction motor does not have any commutator, like the one we
The performance requirement of a squirrel cage induction motor (IM) for application in electric vehicle (EV), with high efficiency, power factor and breakdown
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
The three phase induction motor is the most widely used electrical motor.Almost 80% of the mechanical power used by industries is provided by three phase induction motors because of its simple and
From enclosures protecting and cooling a motor to rotor construction styles dictating how a machine can be balanced, motor construction differences play a
3phase AC induction motors. For industrial and mining applications, 3phase AC induction motors are the prime movers for the vast majority of machines.
Induction Motor Classification. Based on the construction of rotor IM is further classified as. Squirrelcage IM, and; Slip Ring IM. Squirrel Cage Type Construction. It consists of the yoke, wound stator, squirrel
Induction Motors. An induction motor develops torque by inducing current to the rotor, which is proportional to the differential speed of the rotor and the rotating magnetic field in the stator. For NEMA design B motors the differential
Induction motor drives are widely preferred for speed control applications because of its simpler construction, robustness and development in power electronics. Most of these applications need faster response and intelligent speed control logic to achieve higher efficiency along with high dynamic performance.
Construction of AC Motors. Industrial applications frequently use AC induction motors. We’ll discuss 3phase, 460V AC, asynchronous induction motors. When the speed of the rotating magnetic field is more than the speed of the rotor, you know it’s an asynchronous motor (see illustration). The AC motor consists of three basic parts: the
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. Due to the low cost as well as simple and rugged construction of induction motors, these motors are the most widely
This hundredYearold motor invented by the great scientist Nikola Tesla is the most common motor type even today. In fact about 50% of global electric power consumption is due to induction motors. A 3phase induction motor is an electromechanical energy conversion device which converts 3phase electrical power input into mechanical
Construction of SinglePhase Induction Motor. The construction of a singlephase induction motor is very simple, with two main components, a stator and a rotor. As the name suggests, the rotor is the rotating part, and the stator is the stationary part. Both the stator and rotor have windings of wire that produce a magnetic flux or field when
There are 2 main types of the induction motor according to the construction of the rotor of the motor, first one is the squirrel cage motor because its rotor structure is like the squirrel and 2 nd wound rotor
Induction Motor Classification. Based on the construction of rotor IM is further classified as. Squirrelcage IM, and; Slip Ring IM. Squirrel Cage Type Construction. It consists of the yoke, wound stator, squirrel
The main disparity between these two is that the stator is an inactive part of the motor whereas the rotor is the rotary part. Similarly, asynchronous motors like induction and synchronous motors like alternators and generators include an electromagnetic system that includes a stator as well as a rotor. In an induction motor, there are two
These 3 phase motor is supplied with 3 threephase AC supply and is widely used in ships for heavier loads. 3 phase induction motors are of two types, squirrel cage and slip ring motors. Squirrel cage

Induction motor drives are widely preferred for speed control applications because of its simpler construction, robustness and development in power electronics. Most of these applications need faster response and intelligent speed control logic to achieve higher efficiency along with high dynamic performance.
From enclosures protecting and cooling a motor to rotor construction styles dictating how a machine can be balanced, motor construction differences play a key role in purchasing, using, maintaining and servicing these machines.

So, you can find these motors in fans, blowers, centrifugal pumps, washing machines, grinders, lathes, air conditioning fans, and more. 2&3. Capacitor Start and Capacitor Start Capacitor Run Induction Motors. The working principle and construction of these two types of induction motors are almost the same.
Construction of AC Motors. The 3phase induction motor mainly consists of two parts: Stator. Rotor. The stator is a static part and rotor is a rotating part, both are separated by a small air gap, which
This means the motor is sealed so that air is not exchanged between the inside and outside of the motor. The air inside is stirred by the paddles on the end of the rotor body. The fan blade is outside the motor case and pulls air across the motor case to help cool the motor. Fig.1: Exploded view of a threephase induction motor: 1. Fan cover, 2.
The main disparity between these two is that the stator is an inactive part of the motor whereas the rotor is the rotary part. Similarly, asynchronous motors like induction and synchronous motors like alternators and generators include an electromagnetic system that includes a stator as well as a rotor. In an induction motor, there are two
Working Principle of ThreePhase Induction Motor. The stator winding is overlapped at 120˚ (electrically) to each other. When a threephase supply is given to the stator winding, the rotating magnetic field (RMF) induced in the stator circuit. The speed of the rotating magnetic field is known as synchronous speed (NS).
