There were many attempts to design the rotor bar shape to increase the starting torque in squirrel cage induction motor, and it is well known that deep slot of rotor bar increases the starting torque.
This is often done in largeFigure 3 shows the real and reactive parts of the motors in which squirrel cages are fabricatedimpedance of the slot designed for aluminum from bars of material brazed to end rings. Single Cage & Double Cage Induction Motors | Electricalvoice In this article, we will see the difference between Single Cage & Double Cage Induction Motors. Single Cage Double Cage 1. Starting performance As compare to double cage rotor, the single cage has less starting torque so at starting less … Three Phase Induction Motors | Special Designs | Torque Motor
rotor slot permeance harmonics under distorted air-gap flux
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.
Squirrel cage rotor consists of a set of copper or aluminium bars installed into the slots ..... Depth of stator core below the slots: There will be certain solid portion.

Recent Advances in Mechanics, Mechatronics and Civil ...
Induction motors have been ruling the industrial world for many decades. In the induction motors used in lift and hoists, you will see a type of rotor called a slip ring rotor, whereas in most of the other applications you will see a …
This characteristic is analogous to that of a deep-slot squirrel-cage induction motor. Therefore, the speed-torque characteristic of the induction motor employing the squirrel-cage rotor embodying the present invention is analogous to that of the deep-slot squirrel-cage induction motor as shown by the curve A in FIG. 6. Optimization of Motor Rotor: Slot Shape, Frame Size, Rotor ... Optimization of Motor Rotor: Slot Shape, Frame Size, Rotor Diameter SLOT SHAPE 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 ... US3027474A - Squirrel cage induction motor rotor - Google Patents
