Induction Motor Construction | Pumps & Systems

Oct 15,  · Rotors Rotor construction varies according to machine size, application, mounting orientation and manufacturer/user preference. All rotors will consist of conductors (squirrel cage or wound rotor type) housed in a laminated core and mounted on a shaft or other mechanism to transfer torque between the motor and load.

Wound Rotor Induction Motors | AC Motors | Electronics

A wound rotor induction motor has a stator like a squirrel cage induction motor, but a rotor with insulated windings brought out via slip rings and brushes. However, no power is applied to the slip rings. Their sole purpose is to allow resistance to be placed in series with the rotor windings while starting (figure below).

Slip Ring Induction Motor - Construction, Speed Control

Sep 10,  · Construction. The construction of this motor is similar to that of a squirrel cage motor. But there is a small difference in the construction of its rotor. In squirrel cage type, we use rotor bars but in-ring type, we use windings that are connected in star. These windings are connected to the rings.

Types and Amazing Applications of Induction 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. 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.

Double Cage Induction Motor - Construction, Working & Advantages

Jan 15, · Construction of Double Cage Induction Motor : The double cage rotor consists of two separate cages on the rotor. The rotor punchings on a double cage rotor are shown in the above figure. The inner cage, bar A is made up of low resistance by increasing its cross-section area and high inductive reactance.

Three Phase Induction Motor Construction - your electrical guide

A phase wound rotor of three phase induction motor is also called slip ring rotor and the motors employing this type of rotor are known as phase wound or slip ring induction motors. Slip ring rotor consists of a laminated cylindrical core having semi-closed slots at the outer periphery and carries a 3-phase insulated winding.

Dynamic Modelling of Induction Motor

In induction motor too we have torque to be function of ��, the mutual inductance between the rotor and the stator windings. In case of DC motor,by virtue of the construction of the motor, ????�(∅�) and ????�(∅�) are perpendicular to each other.

Three Phase Induction Motor Construction - your electrical

Construction of Squirrel Cage Rotor The motor employing this type of rotors are known as squirrel cage induction motors. Most of the induction motors are of this type because of simple and rugged construction of rotor. A squirrel cage rotor consists of a laminated cylindrical core having semi-closed circular slots at the outer periphery.

Induction Motor Rotor | Electrical4U

Feb 24,  · The operation of an induction motor is not possible with an unequal number of stator and rotor poles, and this type of rotor does not respond automatically to change in a number of stator poles. Hence the number of rotor poles must be made equal to the number of stator poles.

Three Phase Induction Motor: Construction and Working Principle

Construction of Three Phase Induction Motor. Like any electric motor, a 3-phase induction motor has a stator and a rotor. The stator carries a 3-phase winding (called stator winding) while the rotor carries a short-circuited winding (called rotor winding). Only the stator winding is fed from the 3-phase supply.
