How to pronounce “stator” in English

As long as those two pairs of motors, the stator and the rotor, have different poles, that is to say a north pole-- or they have the same poles,

So Tesla's big idea, if we look at this diagram from his 1887 patent, is the doughnut is the stator.

So every time this piece of the rotor gets up there, it has to have a north pole so it's repelled by the stator.

In other words, you change the magnetic field in this, and you leave the magnetic field and the stator stationary.

We're going to induce a magnetic field in the rotor, and we're going to have a rotating magnetic field in the stator.
