Designing Squirrel Cage Rotor Slots with High Conductivity 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 Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted
