Alpha-beta is different than dq. DQ is basically alpha-beta, but rotating at the same frequency as the abc components are, so as to create the illusion that the abc signals we are dealing with are DC quantities as opposed to AC. So, yes, the transformation is not the same.
I am assuming that you are referring to the number of poles that the machine has when you say 2 or 4 poles. The transformation may be applied to any system that can be represented by a space vector/phasor. The condition for that is what I write for the functions around 8:45, and the definition of the space vector is shown shortly after. This definition shows us that the details of the system are not important, just that vector/phasor components must add according to the relationship that we have defined.
Thanks for clearing up the Dairy Queen thing. Was always confused by that
What a fantastic lecture! Thank you Sandeep!
Explained in a very easy and best way
Very good explained.Thank you!!!
Great video brother, thanks a lot. Greetings from Germany
Thank you, glad you liked it. Cheers from Canada.
Very informative video...and really good explained...Thank you so much...🙏🏻🙏🏻
Glad you found it useful!
Thanks for detail, showing mathematics expression to MATLAB block for d-q generation
Nice video sir !
Thanks. Glad you found it useful!
What is a "space phasor" as opposted to a phasor?
what if d axis lead q axis by 90 degrees ,how can we f=derive the transformation matrix?
Thanks for the video. BTW alpha beta matrix, when we project abc on alpha beta, then matrix will be different na?

I need à step by step explanations to master thèse transformations.
Sir plz can u tell me advantages of converting abc to dq0 frame for removing harmonics
Sir,does abc-dq0 transformation depends on number of poles too..or is it same across 3 phase either for 2 pole and 4 pole

Thank you very much! Vary clear explanations.
You're welcome! Glad to hear you found the video to be helpful!
confused don't fb and fc have components in the alpha direction? your matrix seams to indicate otherwise
yes, he made it wrong :)
sandeep bhai kal mera test or ye ques confirm h ke ayega jaha bhi dekhra hu kuch na kuch alg h hope samajh aa jaye
I hope your test went well!
