SQUIRREL-CAGE ROTOR
Reaction of
a squirrel-cage rotor in a 2-pole field in the rotor reference frame: The flux
density wave is moving at slip speed inducing in the rotor cage voltages of magnitude
indicated by the blue vertical lines. Due to the leakage inductance, the
resulting bar currents are delayed as represented by
the red lines. The corresponding rotor-mmf is shown
in the cyan-colored step wave together with its fundamental component.
