basically the induction motor has a stator (copper wire windings within steel laminations wound on soft iron cores, which surroind the rotor) and rotor (coils wound on a laminate iron armature mounted on an axle).

with the rotor coils these are often just single copper bars which are connected at the ends by a ring or dissc of copper whic allows current t flow in a loop between opposite bars. so in effect this thingy look like a "squirrel cage".

current flows, emf is induced, alternating current produce changing magnetic fields, eddy currents are induced in rotor coils by the rotating magnetic field of stator.

eddy currents produce their own magnetic fields and these interact with the rotating field of the stator. this produces a torque on the rotor in direction of rotation of the stator field.

personally i dont completely understand it. this is just from my notes.

does this explain it or is it too complicated?
