Teaching Old Motors New Tricks -- Part 2
Переглядів 98,465
10 років томуWhile motor topologies have remained relatively unchanged over the past century, control techniques by comparison have experienced explosive growth. This has been driven in large part by technology advancements in the semiconductor industry. This seminar focuses specifically on advancements in the control of motors, with an emphasis on field-oriented principles with brushless AC motors.
This video is part 2 of a 5-part series and covers Field Oriented Control of Permanent Magnet Synchronous Motors.

we need more of this type of lectures these days. people from industry with lots of experience, teaching new engineers.

@2.20 - 2.25 "This is spatial representation, not phasor representation". That simple statement has cleared up so much of my confusion on this topic!

"Mod-01 Lec-17 Dynamic Equations of Induction Machines". If you type it on youtube, at around 20 minutes of the first part of the video is about it there are both "spatial representation and phasor representation".

I finished watching all of these lectures and this is my second time watching them again. I also watched all of the Control System lectures by Richard Polley that preceded these. It was really intense and extremely informative. It's starting to sink in though! Thank you for sharing this with us.

These lectures are excellent! Thank you. I'm not going to waste too much time with BLDC projects ever again. I just learned about FOC yesterday and I'm never doing it the old way again.

Quote: _"I just learned about FOC yesterday and I'm never doing it the old way again."_ Same here. I had trouble finding any info on sensorless Delta commutation. The focus seems to be on the Wye configuration. The problem with the Delta wound BLDC is that all three phases are energized simultaneously. I'm going to experiment with current sensing circuits.

Amazing teacher. I wish I had the same quality of teachers during my university years.

Best lecture about motor control I've ever seen.
@j-tech9156 4 роки тому
I worked on a motion controller and end up with a good servo Driver.But I had couple of things that was hard to understood. After this, i got answers for most of my problems.And the lecturer is a best one that i have saw.Amazing ! From SL

Why these videos do not appear at the top of the list in searches for motor control, foc, etc? Please TI promote them more!!! Amazing content!

awesome, clear, easy to understand lecture. Does this series cover AC induction motors at any point and how to handle the i(sub d)? This is also known as the flux current in the rotor. Asynchronous motors work just like they sound, the rotor is out of synchronous alignment with the stator EMF, inducing current thru the rotor - asynchronous motors do not have permanent magnets.

Excellent classes please can you help me how to adjust zero to servomotors that use resolver with the help of the oscilloscope thank you very much greetings from Venezuela

I like your lecture 😍
@Brazylizsek 5 років тому
Does anyone remember when did he say that DC motor is actually AC motor where FOC is performed by its mechanical structure. I'm pretty sure it was in one of his 'teaching old motors new tricks' serie.

@Texas Instruments: Does this software simulate available for free in your website? Please let me know and I appreciate for your help. I really interested in this whole topic

i filled a HD bucket with water and made some soap bubbles. when you stop spinning it is easier to see what was stationary in the rotating frame was infact rotating.
@ibraheeminam4982 7 років тому
If i use a series PI Regulator for Torque and Flux currents, do the regulator gain deterministic calculations remain same as mentioned in the lecture part I? i.e. we have to cancel zero of PI regulator with the pole of motor winding. If it is so, then how we will relate the 2 PI regulator zeros with 3 winding poles (L/R) since it is a 3 phase machine and we have only 2 PI regulators?

hello sir, do you already have an answer for your question. If you do, could you please explain it to me in few sentences? Thank you!

I have some questions !
@anabrr 4 роки тому
There is something I don't unserstand. Space state representation is not Phasor representation... Then what are this signals actually? Are we working with magnitudes only? What about the frequency of these signals?

@keatsful1 7 років тому
Can FOC be applied on single phase induction motor?
@TheFootbaldd 5 років тому
I don't see why not, but the question would be why? That is an honest question. If you are going to introduce control, why would you use a single phase motor? You already have start windings. I would suggest it goes against reason to build a controller for a single phase motor.

I think there is something wrong with coffee cup analogy, actually the observer have to get inside of the cup and start spinning himself in same direction as that of bubbles, than only bubbles would become stationary.
