- I'm trying to understand how a Permanent capacitor motor, of the type single phase induction motor, that is used in ceiling fan, works.

I'm trying to understand how motor of ceiling fan works. I have been scouring the internet since last 3 days. Watched a lot of youtube videos about it. Read quite a lot of websites related to single phase induction motors. Also read relevant chapters in 2 books about it. Till so far, I have come to the conclusion that the motor used in ceiling fan as shown in the picture is a single phase induction motor, and more specifically, the Permanent capacitor motor.
However, the youtube videos explain 3 phase induction motors, which i think has been explained quite good. Even in the videos which do explain single phase induction motor, the explanation is: the starter coil and the running coil create a rotating magnetic field. But how that rotating magnetic field is created(at intuitive level, or at math level) has not been explained at all. How the torque is created and transferred to the rotor, has not been explained at all.
I'm hoping that someone who has seen the pic that i have posted alongwith this post, and understands this type of motor would be able to guide me in understanding how this motor actually works, at the minutest level. If there is any book, resource etc, that in your opinion would help me in understanding this particular motor would be much helpful.
I'm an undergraduate student. I understand the impact on a closed conductor in a time variant magnetic field. I understand how electricity is induced in that closed coil. I also understand that a force acts on a current carrying conductor when placed in a magnetic field. What I'm failing to understand is that, in that particular motor, as shown in the pics,
how:
1) A rotating magnetic field is created. I'm talking about this particular motor only.
2) How the torque is created in a particular direction.
3) How that torque is transferred to the rotor of that particular motor.
