15:12- Slip regulator will restricts the operation above (not below) the Break Down Frequency (B.D.F) . So, output of Slip regulator will be always the slip frequency equal to or below the B.D.F

This level of clarity and didactic is what one would expect from a lot of professors. Thank you very much for this wonderful explanation :)
Thank you so much, I’m a PhD student and found these videos you make are really helpful.
Thank you everyone. Ill try to do the simulation ASAP. Thanks!!!
10/10 for the Video
Please Make More & More Technical Videos sir
Same as this which will help both Students and Industrial Employees
It was a great video and your voice is clear. Hope a subscriber motivates you
really helpful videos sir.
Thank you very much
Thanks for sharing your knowledge and time in making this wonderful video. 😊keep rocking. Subscribed your channel 👍
Sir you explained very well, if you do the simulation part ,that will be great and more understandable
Waiting for simulation
very nice explanation
sir, why after PI controller, the error becomes slip-frequency?
Brother I got a good information… thanks
alguien me puede decir que es esa p de p/120 ?, no entiendo que es lo que dice 10:53
Good Job 👍
Thank you
I Liked Commented and Subscribed
I would like you to put up a video series of complete closed speed control of IM3phase both hardware and software..
Sir I have a question: In the closed loop why the input of the PI block is N* but the output is F*?????
do a video on sensorless v/f control method
how one can get voltage/frequency lookup table for this scenario?
outstanding
thank you for the video, Why need to add fn ?
I could not understand what is this "Yenness" and "Yeffen" ? Can u please explain it
How do we know the Lookup table for the V/F control? It will be a property of the motor..
Please do cvcf working principle
how to get the values of PID?
I am waiting for simulink model.when you will show us.
Can you do a video on sensorless v/f control
Hello
Thank you very much, but i have a small question
First , how to make look up table frequency and voltage
Second question, if the circuit is a single phase i mean if the inverter is a single phase how to connect the control loop with it
Thanks a lot
First, In software like MATLAB/PSIM you can use look-up table easily. Because it is available as a component. For implementation of look-up table you can use any DSP controllers. Second for a single phase inverter circuit you can realize the PWM control circuit by generating two sinusoidal signal (reference signal) with 180 degree phase shift and one triangular signal. Operation is similar to three phase. In future I will try to do another video. Thank you!
What does the star mean on w? And the star on f and N? Do they mean same thing?
hi bro, when will you be doing the open loop and close loop control of induction motor? I want to check how draw 1kw power hybrid wind solar to induction motor , so far i did resistive load as an output , how do i change it to induction motor with 1kw?
Why you have written f-fn Slip Freq. ? Isn;t it should be only Control Signal after PI Controller ?
Why regulator ? What will be limits ?
instead of f* can't we write (N-N*)*P /120 ????
Hi sir, the video is excellent. Can you please show us how to create the look up table in MATLAB!!
Look up table 1D or 3D
@@BTECH123 lookup table for v/f control of IM
How will calculate the Loop up table in V, F ?
2. Any formula is for calculating V,
Can you share me
Based on the desired rotor speed, calculate frequency f. In simple voltage V = f+(IR+IX)
Can you do "Close Loop Control" in Matlab-Simulink? Thank bro 💙💪⚡
Sure. Probably using PSIM
Hello, do you have a Simulink model for closeloop control and how can I set the look up table on Matlab. Thanks for the great video :)
Yes in my channel. You may visit if u are interested
How can we read the load current and voltage on the induction motor?
Usually we will read it using voltmeter and ammeter. Sorry I cant understand your question.Thanks!!
what is p/120 element?
p stands for no of poles of IM and this element is multiplied with N(Speed) which is formula for converting N (speed) to frequency f, basically we do this to get frequency.
Slow your speed of talking down. You are not pronouncing your words fully. Add high speed and you make it difficult for people to understand. Or put captions.
