  • Wound Rotor vs Squirrel Cage

     · Squirrel cage motors have been used in the auto shredder appliions, BUT the tons/KWH is less for a SCIM than for a WRIM, all things the same. Unless you have actually been to and worked in an auto/industrial scrap yard where the cars/busses, etc are sherdded from their present form to 'halfdollar size' in less than 10 seconds the true appreciation of the WRIM will never be appreciated.

  • Squirrel Cage Induction Motor

    The principal advantages of the squirrelcage induction motor are its simplicity of design and robust construction. Its torque/speed and current/speed characteristics are such that, on starting, a torque of typically twice fullload torque is produced but a large current (typically, six to eight times fullload current) is drawn from the supply. It is this latter aspect of the current drawn ...

  • What is a squirrel cage motor used for?

    What is the principle of operation of squirrel cage induction motor? Squirrel induction motor working is based on the principle of electromagnetism. When the stator winding is supplied with a threephase 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 the importance of end rings in squirrel ...
