SUMMARY

The discussion centers on the feasibility of using permanent magnets as a stator in a rotating magnetic field motor, specifically in brushless motors. The user highlights the confusion surrounding terminology, as a stator is traditionally defined as a non-rotating component. The conversation emphasizes the role of the speed controller in synchronizing the rotating magnetic field with the rotor's speed. This innovative approach challenges conventional definitions and opens avenues for further exploration in motor design.

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.
