AI Thread Summary
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.

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.

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

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
