Can someone see this site, and explain the concept better?

Hi.
I'm interested to learn more about induction motors.
Could someone please see the following site and explain it better, or
point me
to another site that may explain it better for me to understand?
formatting link

Thanks, Roger

Looks OK to me, why not go down to the library and pick out an author who writes in a style that you find better ? Possibly it would pay to study the basic electrical theory first ??

Do you know how a transformer works? An induction motor is essentially a transformer which has a secondary winding (shorted) that can turn. It is easier to first look at a 2 or 3 phase machine where it can be shown (a bit long for an e-mail) even by a hand waving approach, that a rotating magnetic field can be set up by stator currents. If there is a speed difference between the rotor and this field - there will be voltages induced in the rotor which causes currents which in turn cause a rotor magnetic field which is not aligned with the stator field (but turns at the same speed) and tries to get aligned, so torque is produced. The rotor itself turns at a speed which is smaller than the speed of the stator field so is said to slip. In a way the induction motor is an electrical equivalent of a fluid transmission - there is always some slippage and this increases as the torque demand increases. The torque production is based on the same principles as in a DC machine but the induction motor is much simpler. I do have some notes but they do involve some math and AC circuit theory.
