What is Squirrel Cage Induction Motor. A 3 phase squirrel cage induction motor is a type of three phase induction motor which functions based on the principle of electromagnetism. It is called a 'squirrel cage' motor because the rotor inside of it - known as a 'squirrel cage rotor' - looks like a squirrel cage 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 Squirrel Cage Induction Motor Working Principle Squirrel induction motor working is based on the principle of electromagnetism. When the stator winding is supplied with a three-phase AC, it produces a rotating magnetic field (RMF) which has a speed called synchronous speed. This RMF causes voltage induced in the rotor bars What is squirrel cage induction motor? In simple words, the induction motor which uses a squirrel cage rotor is called squirrel cage induction motor. The reason behind the name squirrel cage is because of the type of rotor used in these motors. In these type of motors, the rotor is simplest and most rugged in construction API 547 General Purpose Squirrel-Cage Induction Motors 250 hp and Larger, Second Edition, 2017.

MENZEL squirrel cage induction motors are manufactured for various industries and industrial applications of all kinds. MENZEL squirrel cage motors are available in all standard motor cooling and protection types for low-voltage from 75 kW as well as medium and high voltage up to 25000 kW (25 MW) Squirrel cage induction motors are more sensitive to the supply voltage fluctuations. When the supply voltage is reduced, induction motor draws more current. During voltage surges, increase in voltage saturates the magnetic components of the squirrel cage induction motor. Speed control is not possible in squirrel cage induction motor Description. The Induction Machine Squirrel Cage block models a squirrel-cage-rotor induction machine with fundamental parameters expressed in per-unit or in the International System of Units (SI). A squirrel-cage-rotor induction machine is a type of induction machine. All stator connections are accessible on the block Key Differences Between Slip Ring & Squirrel Cage Induction Motor The motor whose rotor is wound type such type of motor is called slip ring induction motor, whereas the squirrel cage motor, has a squirrel cage type rotor. The rotor of the slip ring motor has a cylindrical core with parallel slots, and each slot consists each bar A Squirrel cage induction motor does not contain Brushes, Slip rings and Commutators. Due to this reason, the cost of the motor is quite low. However, Slip Rings are used in Wound type induction motor to add external resistance to the rotor winding. Due to the absence of Brushes, there are no sparks in the motor
Third International Conference on Advances in Control and Optimization of Dynamical Systems March 13-15, 2014. Kanpur, India Design of a Three Phase Squirrel Cage Induction Motor for Electric Propulsion System Ravi Prakash*,Mohammad JunaidAkhtar**, R. K.Behera**, S. K.Parida** *Department of Electrical Engineering National Institute of Technology, Silchar ,Assam, India (e-mail: [email protected]) 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 Type: Squirrel Cage Induction Motor Ratings: 0.55 kW ~ 375 kW Duty Rating All motors have a maximum continuous duty rating of S1 under rated load. For duty cycles other than S1 please refer to TECO. Supply Voltage Stock motors are designed for operation as below: 2.2kW and below : 220~240V/ 380~415V 3 phase /50Hz 3 kW and above : 380~415V 3. Now let us discuss in detail, the most common form of induction motor, the Squirrel cage induction motor. The reason for the name Squirrel cage is because of the type of rotor used in these motors. Almost 95% of the induction motors used is of squirrel cage type
The most popular squirrel cage induction motor is of a 4-pole design. Its synchronous speed with a 50 Hz supply is therefore 60 f/p, or 1500 rpm. For a full-load operating slip of 3 per cent, the speed will then be (1 - s)60 f/p, or 1455 rpm. Top Squirrel cage induction motor: Type of alternating current induction motor in which the rotor winding has little resistance and thus carries very high current. To withstand high currents, the rotor structure is modified and more resembles a cage than a winding Squirrel cage motor is better cooled compared to slip ring induction motor. Squirrel cage motors operate at nearly constant, high overload capacity, and operates at better power factor. Squirrel cage motor is explosion-proof due to the absence of brushes slip ring and brushes which eliminates the risk of sparking 3 Phase Squirrel Cage Induction Motor Langrui is a reliable 3 phase squirrel cage induction motor manufacturer that can provide low voltage squirrel cage motor and high voltage squirrel cage motor.

After the maximum torque point (which is three to four times the full-load torque), the decrease in rotor* p.f. is greater than the increase in rotor current resulting in a decreasing torque and the motor quickly comes to stop A squirrel cage induction motor therefore draws a very high starting current, as noted in Section 1.2.1. However, it reduces substantially in a slip-ring motor due to the high impedance of the rotor circuit. The starting of an induction motor does not relate to simple switching alone
