No matter where I go and read or ask a question about the principle of induction motor operation, all I find is that the magnetic field alternating direction in each pair of coils begin to join together and become just one rotating ( perhaps non-changing) magnetic field that the rotor begins to chase.
What I want to know is the exact science, the law that makes this happen. What is the cause of the fields joining as one? No one has given me a straight answer except resorting to some fancy lingoes that all it does is make my head hurt. And when I push it I become the bad guy.
The resort to avoid the details of the subject especially becomes obvious when I bring up a single-phase induction motor. How does the single field with two poles changing polarity begin to suddenly rotate as now there are no other fields it can combine with. Worse yet the word oscillating is used.
And I am sorry to say that even though English is my second language, it is a totally false word to use to describe the field either single or multiple fields. First of all, oscillation applies to a pendulum swing type of phenomenon. All you have to do is just open a dictionary. It is something swinging side to side and their ends don't switch position. That is oscillation.
If I toss my ball at you and you toss your ball at me we are alternating the position of the ball and our actual balls move, heck you can even do it with just one ball, the same thing. That is tossing back and forth one or two balls. Nothing is oscillating, it is simply alternating and changing position by one moving and switching with the other If you swing the pair of coils back and forth for some no good reason I suppose the field in between also swings or you can say oscillate back and forth like a pendulum.
Now that is out of the way.
So right to the point:
( I have no interest in someone using the term mathematical-equivalent), the real-world equivalent will do if you will for me. As the magnetic field's polarity switches position between the pair of coils, how does that suddenly begin to rotate, and evidently no other pair is needed to join in, be it two or three or 10? And furthermore not only rotate but it couldn't be changing polarity at the same time or the rotor would be very confused. The north is chasing the south when suddenly the south becomes north, doing two things at the same time. Nah, if I was a rotor, I would not feel comfortable.
Furthermore, if it does rotate and also doesn't change polarity for the sake of explanation then why on earth it needs a starting coil of some sort to help, and then mind you get out of the way and then the magnetic field between the two coils begin to leave the coil and move to revolve, rotate agoing round and round if you will.
I believe that this RMF ( the sheer abbreviation and the sound of rotating magnetic field) is nothing but a catchy hollywood lingo, no different than "The observer effect", "The spin up and down" and the rest. And let us not forget the Lorentz Force just for special effect. Hey Bobby, what causes that to happen, what is behind it? And Bobby straightens himself looking at Joe with a look of knowing of that esoteric knowledge as he exclaims..." It is the Lorentz Force Joe" as he glances away and moves on into the unknown.
And let us not forget that anyone who truly understands and firmly knows that the field does rotate will have no trouble explaining and will have absolutely no trouble to convince me. Anyone who simply repeats what they have heard and with all credentials will be left empty-handed with me as they will walk away. Since I am real, I won't walk away as I have all the energy to find out what I am missing. What drives me is understanding and that is totally different than memorizing and repeating. There is an unbridgeable qualitative difference between one and the other.
I am sorry. This is not an attempt to be unsocial or impolite. It is an attempt at intellectual and scientific honesty.
