Discussion Overview

The discussion revolves around the concept of using permanent magnets in a stator configuration within a rotating magnetic field motor, specifically exploring the idea of changing polarities in relation to the rotor. The conversation touches on the mechanics of motor design and comparisons to internal combustion engines.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions the feasibility of using permanent magnets as a stator that rotates to change polarities in relation to the rotor, drawing an analogy to the operation of intake and exhaust valves in an internal combustion engine.
  • Another participant asserts that if the component rotates, it cannot be classified as a stator, which is traditionally defined as a non-rotating part of a motor.
  • A third participant clarifies their use of the term 'stator' to maintain perspective in the discussion, indicating a desire to avoid confusion between similar terms.
  • A fourth participant introduces the concept of a brushless motor with stationary windings and rotating permanent magnets, providing a link to an image that illustrates this design, and mentions the role of a speed controller in synchronizing the magnetic field with the rotor's rotation.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the definition and role of the stator in the proposed design, with some supporting the idea of a rotating stator and others contesting the terminology and feasibility of such a configuration.

Contextual Notes

The discussion does not resolve the definitions of stator and rotor in this context, nor does it clarify the implications of using permanent magnets in a rotating configuration. There are also unresolved assumptions about the mechanics involved in the proposed 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.
