Construction of squirrel cage induction motor explained
Squirrel Cage Induction Motors & 2. Slip-Ring or Wound-rotor Induction Motors. Construction Of Squirrel Cage Induction Motor. Any Induction Motor has a Stator and a Rotor. The construction of Stator for any induction motor is almost the same. But the rotor construction differs with respect to the type which is specified above. Stator:
Double Squirrel Cage Induction Motor - your electrical guide
Construction of Double Squirrel Cage Induction Motor. A double squirrel cage induction motor consists of a rotor which has two independent cages one above the other in the same slot. A double squirrel cage rotor is shown in the figure. The upper slot conductors from the outer cage and the lower slot conductors form the inner cage.

Double squirrel cage motor By Kiran Daware AC Machines , Induction Motor Squirrel cage motors are the most commonly used induction motors, but the main drawback in them is their poor starting torque due to low rotor resistance.
Squirrel Cage Induction Motor: Working Principle ...
We stone the construction of the Squirrel cage induction motor. The main difference between slip ring and squirrel cage induction motor is the rotor construction. Motors have main two parts in construction: stator and rotor. In these motor, the rotor is squirrel cage type. This rotor is made up from parallel aluminum or copper bars.
Double Cage Induction Motor - Polytechnic Hub
In case of 3Ø squirrel cage motor has low starting torque. This is due to the low Rotor Resistance. Then, the starting torque with increase but at the same time their will be more copper loss and %n of motor will decreases. The double cage motor is so develop that it overcomes the above difficulties and given good starting torque with good efficiency for that purpose.
Double Cage Induction Motor: Construction, Working
Double Cage Induction Motor One of the advantages of the slip-ring motor is that resistance may be inserted in the rotor circuit to obtain high starting torque (at low starting current) and then cut out to obtain optimum running conditions.
Deep Bar Double Cage Induction Motor | Electrical4U
Hence, this squirrel cage single bar single cage rotor is not being able to apply against high load. We should go for deep bar double cage induction motor to get higher starting torque. Construction of Deep Bar Double Cage Induction Motor. In deep bar double cage rotor bars are there in two layers. Outer layer has the bars of small cross sections.
Single Phase Induction Motors - Construction & Working ...
The induction motor never rotates with the synchronous speed but rotates at a speed that is slightly less than the synchronous speed. The rotor construction is of squirrel cage type. This rotor consists of uninsulated copper or aluminium bars, placed in the slots.
Squirrel Cage Induction Motor: Working Principle ...
Jul 25, 2019 · Squirrel Cage Induction Motor Working Principle. When a 3 phase supply is given to the stator winding it sets up a rotating magnetic field in space. This rotating magnetic field has a speed which is known as the synchronous speed.. This rotating magnetic field induces the voltage in rotor bars and hence short-circuit currents start flowing in the rotor bars.
What is Double Cage Rotor of an Induction Motor? - Circuit ...
Double Cage Rotor of an Induction Motor A Double Cage Induction motor is that type of motor in which a double cage or two rotor windings or cages are used. This arrangement is used for obtaining high starting torque at a low value of starting current. The stator of a double cage rotor of an induction motor is same as that of a normal induction motor.
Double Cage and Deep Bar Squirrel Cage Rotor Induction ...

Squirrel Cage Induction Motor - The Engineering Projects
Oct 09, 2016 · A 3 phase induction motor has two types based on the rotor construction, named as: Squirrel Cage Induction Motor and Wound Rotor Induction Motor. Former is cheaper and broadly used as it requires less maintenance than later one. Firstly, I am going to tell you about the structure of squirrel cage induction motor. Afterwards I will cover the ...
Squirrel-cage rotor - Wikipedia
A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor.It consists of a cylinder of steel laminations, with aluminum or copper conductors embedded in its surface. In operation, the non-rotating stator winding is connected to an alternating current power source; the alternating current in the stator produces a rotating magnetic field.

Double Squirrel Cage Motor - electric equipment
Jun 06, 2015 · Double Squirrel Cage Motor. The main disadvantage of a squirrel-cage motor is its poor starting torque, because of its low rotor resistance. The starting torque could be increased by having a cage of high resistance, but then the motor will have poor efficiency under normal running conditions (because there will be more rotor Cu losses).
Induction motor - Wikipedia
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 by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motors rotor can be either wound type or squirrel-cage type.
Double Cage Rotor | Circuit Modelt - EEEGUIDE.COM
Oct 23, 2016 · Double Cage Rotor – A rotor design, which though more expensive gives still better starting, and running performances than the deep-bar design, is the double-cage rotor. The squirrel-cage winding in this design consists of two layers of bars short-circuited by end rings.
Rotor : Construction, Working Principle,Types and Its ...
rotor Construction and Working Principle of a Rotor. In a three-phase induction motor, once an AC is applied to the rotor then the windings of stator strengthen to generate a rotary magnetic flux.The flux generates a magnetic field in the air gap among the stator & the rotor to induce a voltage for generating the current throughout the bars.
