Construction of squirrel cage induction motor explained Know about the most popular and almost unbreakable construction of Squirrel Cage Induction Motor. Know about the different winding slots, lamination of the stator and its construction. Also appreciate the rugged construction of squirrel cage rotor and know the spectacular reasons for the skewed arrangements of the rotor conductors. Squirrel Cage Induction Motor - an overview | ScienceDirect ... The wound-rotor motor is a variation of the squirrel-cage induction motor. While the stator is equivalent to that of the squirrel-cage motor, it has a set of windings on the rotor which are not short-circuited, but are terminated to a set of slip rings. These are helpful in adding external resistors and contactors. Shape Design of a Rotor Bar for Improving Starting Torque And ...

conductivity of cast copper in rotors of induction motors. Deep bar and multiple cage effects are useful in design of such machines. It is shown 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.
