Rotating Stator: Permanent Magnets & Rotor Polarity Change

[deuel18]

Hello. I just want to know if it is possible to have permanent magnets as Stator in a Rotating Magnetic field morot. However, these Stators rotates to change their polarities in relation with the Rotor. Much like the harmony of Intake/Exhaust valves in an Internal Combustion Engine.

If it rotates, it's not a stator, which is defined as not rotating.

I know but i just used the 'term' so readers could see the perspective I am at. Because if I say rotor and then rotor, what's the difference? So I had to use the same term.

Brushless motor with stationary windings in the middle and permanent magnets rotating around it...

The speed controller makes the field in the windings rotate at same rpm as the outer rotor.
