The discussion centers on the mechanics of a 3-phase motor and the phenomenon of rotor spin versus simple attraction to the magnetic field. The key factor is the creation of a rotating magnetic field, which induces angular movement in the rotor. This is a fundamental principle in AC motor design, distinguishing it from DC motors. Visual aids, such as animations, are recommended for a clearer understanding of this concept.
PREREQUISITESElectrical engineers, motor design specialists, and students studying electromechanical systems will benefit from this discussion.
Rotating magnetic fieldkolleamm said:Assuming we have a 3 phase motor I've always wondered why is it that the rotor spins rather than just being compleltly pulled towards the direction of the phase or the electromagnet? What causes that angular movement?
