What is a Squirrel Cage Motor and How Does it Work?
Squirrel cage motors maximize electromagnetic induction by utilizing rotor bars to interact with the stator's EMF. The stator usually contains windings of wire which carry an AC current; this current changes in sync with a sinusoidal curve (or "alternates"), which changes the current direction in the wire windings.
