Permanent magnets can be used in a rotating magnetic field motor, but the terminology can be confusing since "stator" typically refers to stationary components. The discussion highlights the concept of using rotating elements to change polarity in relation to the rotor, similar to the operation of intake and exhaust valves in an internal combustion engine. The brushless motor design features stationary windings with rotating permanent magnets, which is essential for creating the desired magnetic field. A speed controller is necessary to synchronize the magnetic field's rotation with the rotor's speed. This innovative approach allows for efficient motor operation while maintaining clarity in terminology.
