In this image, armature flux is increasing under the north pole after the north pole axis. It can only increase if the armature mmf is increasing because under the poles, the reluctance is constant.
The same goes for under south pole before the south pole axis.
I think taking this thing into...
Yes, even I was thinking that mmf should be upside down with the shown current direction.
If we consider this equation "MMF = flux*reluctance", can we deduce something?
This is informative. But I got one more doubt here. According to this picture ,
The MMF should increase in direction of red to light violet, but the armature MMF is shown to be decreasing. please correct me where my understanding is going wrong.
Even though this is basic, this is something new for me. With this I understood why the stator and rotor flux should have same speed. Thank you.
Pardon me for being weak in basics but I have just started learning about these machines and I still learning. Queries like these may come from my...
The author is smoothing/adding the step waves to obtain the triangular wave as you said in one of the comments. But how the step wave is obtained on the first place? I am not able to figure this out.
This is right. But what I want to know is how it will effect the machine if their angular speeds are not same? Like what will the effect on torque developed or efficiency.
The rotor and stator flux speed are stationary with respect to each other in 3 phase induction motor. What will happen if there is relative speed between them? How these two fluxes interact with each other to develop a torque?
I applied right hand rule on the pair of conductors as you showed and the direction of flux was downwards. I still don't understand how it forms a step wave.
Can you please explain how step wave is obtained due to uniform air gap?
Also, I am really sorry to take your time but I didn't understand what the above picture wants to say.
