Jul 08, 2017 · 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. Designing Squirrel Cage Rotor Slots with High Conductivity Designing Squirrel Cage Rotor Slots with High Conductivity I. INTRODUCTION: There has been, in recent years, an effort to make cast copper rotors for industrial use induction motors. The objective is to make motors more efficient because of the higher conductivity of copper. In addition, the reduced Squirrel Cage Fan Motor for sale | eBay

What is a Deep Bar Rotor? - Circuit Globe Deep Bar Rotor The Deep Bar Rotor in an induction motor is used to obtain high rotor resistance at starting and low rotor resistance at the running condition. The figure below shows a deep bar cage rotor with deep and narrow bars. Designing Squirrel Cage Rotor Slots with High Conductivity… Designing Squirrel Cage Rotor Slots with High Conductivity motors. Deep bar and multiple cage effects are ... that a useful understanding of how different slot shapes work may be developed through the use of frequency response curves that describe rotor slot impedance as a function of rotor frequency. Good starting, running and stray loss ... Double squirrel cage motor | electricaleasy.com 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. (Starting torque is directly proportional to the rotor resistance).But increasing the rotor resistance for improving starting torque is not advisory as it will reduce the efficiency of the motor (due to more copper loss).
