Transfer of knowledge and understanding. Very Good. Thanks you very much.

[@jonbrown3273]

Finally an explanation that doesn’t hide behind the maths! Thank you!

[@sarathsanthar3560]

this gave me a clear explanation as to why the rotor has a special construction. Thank you for making a useful video!

Many thanks for this excellent explanation video!

[@apdahlen5282]

Thanks

[@surendersingal2192]

Thank you sir Does it mean reluctance motors are always meant for low continuous speed or stepoed motors?

[@DavidDrivesElectric]

This video has become very interesting now with Tesla's Model 3 using a reluctance motor!

[@harshalhbhosale]

True, came here because I was researching the Model 3 rear motor!

[@NRG1985]

It's most likely an Interior Permanent Magnet synchronous motor, which by the way exploits partially the reluctance mechanism. For instance the Toyota Prius is quite similar from the appearance, main difference is the pole number, 8 vs 6 of the Tesla. If you read the EPA is stated that, but if you read internet you can find many different things, like switched reluctance (Elon Musk's tweet)..etc. I don't understand why there is some kind of mysticism around this topic...

[@harshalhbhosale]

@@NRG1985 well the mysticism is probably because most of us are having trouble decoding it's working mechanism!

[@kreynolds1123]

Thank you for this video. Subscribed because of it. I'll be going through your other videos. But if you have not yet, would you describe the theory behind using one of these motors as a generator?

[@ameyadesai6382]

Beautifully explained. Thank you Sir.

[@kelvinpraises]

This was so good and short, that it made me sad.

[@sebastianbergman1099]

Excellent video! Clearly gives an insight into the basic principles of the motor.

[@hakonbye7232]

Very good video! I did not understand the conservation of energy part. Is the lowest enegy state where most energy is stored in the magetic field?

[@monstercolorfunco4391]

Cheers, I was hoping that there would be an animated illustration of the rotation and force change, this is the closest i have seen... I only understand motors which are pulling sideways on the closest magnets. Therefore i didn't understand where the tangential draw is.

[@paragkolte8681]

Very nicely explained concept of reluctance motor.

[@mioumitsou]

thank you, are the lines in the rotor steel while the dark air?

[@pratikshendure2126]

amazing..... plz teach all machines concepts..... the explaination is so smooth thanks a lot sir

[@chiwetaemmanuelabunike949]

Nice explanation!! What is the difference between synchronous reluctance motor and switched reluctance motor? Are they the same? Please, can anyone clarify this. Thanks

[@Jajaho2]

Very well explained, even I got it.

[@johanponin1360]

Beautiful. Never say sorry when providing such good videos :)

[@Buzzhumma]

So for the motor to start does the controller send some repel pulses synced with attract signals to get some momentum in the rotor?

[@TheDIYer]

can you show different types of winding and how to do it in real . not theoreotically but practically

[@Rudisbashar]

Twelve discipels,12 months,4 seasons,the sun its path,its a horoscope,a compass,a watch.its nature’s cycle. Its a torusfield,its a mo-torus,old old principles wich our universe works with. Following the field lines of nature. Were children finding nature wonders.

[@killawee118]

I've been out of school for a while not working in the field. This video was awesome for me!

[@suryaprathap2727]

Can you make video for design of reluctance motor

[@praveensarat]

It indeed is a perfect explanation, thanks for the video.

[@Buzzhumma]

Make it as long as you like. I'm all ears. Well done keep going 😊

[@bjornnordling269]

Nice video, thank you.

[@khiyabarrett1459]

Hey mate, amazing video, I'm curious, what video do you first explain reluctance?

[@apdahlen5282]

Thank you. You may be interested in time index 22:00 of this video kzbin.info/www/bejne/fKO8mGiahNSWgJY

[@Scrogan]

Interesting stuff! For a year or two I thought the only sorts of AC magnetic motors were permanent-magnet motors and asynchronous induction motors. But now I know about reluctance motors, and I think there might be another sort I’m missing too. I’m also considering the electrostatic analogs of these, being permanent electret motors and asynchronous electrostatic motors. By using multiple dielectric materials in the core (just insulators and conductors, perhaps?) I assume you could get an electrostatic reluctance motor too.

[@Eng_Simoes]

Usually feasible only in very, very small dimensions

[@PranayPratyush]

Brilliant video

[@varimas]

Sir. Very good video. You have showed how to start the reluctance motor using three phase? Is it possible to start using a single phase supply only.

[@aleksandar4756]

Subscribed and liked. Great narration.

[@camiemengineer]

VERY good!

[@emiledestructeur]

Hey great video! Could you make one covering how it is that having more rotor poles than stator poles enhance power density in a switched reluctance machine?

[@monstercolorfunco4391]

I don't believe that having no magnets in the stator can yield more force for the same weight.

[@sachinanand467]

Excellent presentation👌. Easy explanation🙌. You should make more videos!

[@EvanDower]

This is great, thanks! Now I'm just confused about how PMaSynRMs work. It seems like the reluctance and the PMs would be trying for slightly different alignment, so I feel like I must be misunderstanding something.

[@hienvuvg]

Thanks for your great explanation, that's clear and straightforward. At 4:29, in my understanding, activating the north-south coil should make the rotor roate because the coil will create its north and south poles which attract the corresponding poles of the rotor but you said that it will do nothing. Did I miss anything in your assumption? Please let me know. Thanks!

[@1992jamo]

It's just because if the rotor is perfectly straight, turning on the north south coil wouldn't attract one side more than the other. In real life it probably would flip, but it might not be fast to begin, and it would also not be predictable which way it flips

[@hienvuvg]

@@1992jamo Thanks for your comment. Because the rotor has two poles north and south, in case the rotor is horizontally straight as in the video, activating the north-south coil will creates north and south poles to attract and repel the corresponding poles of the rotor. So, I think the movement of rotor in this case is predictable.

[@1992jamo]

@@hienvuvg I see what you mean, but if the rotor is perfectly 90 degrees parallel to the coils, then the long flat sides of the rotor would become the poles rather than the ends. If the rotor was 91 degrees, there would also be some of the magnetic flux going in to one end and out the other, which would cause the rotor to want to turn to reduce the reluctance.

[@andyg.3509]

Fantastic Explanation!

[@janeshnm2226]

Explains clearly and simply... Thank you

[@apurvmj]

Once you yourself understand the concept you can explain it better 👍

[@MarcusMussawar]

Thank you

[@parikshitmusic510]

Why don't you make long lecture videos Your explanations are very different

[@sanjaymadhavan1893]

Do you watch jordan peterson a lot?

[@qc6948]

Excellent explanation! Would be great if you can share some gifs

[@25152026]

excellent explaination

[@joshmnky]

Can you explain what the extra rotor lines are for?

[@MrZauberwuerfel]

if you mean the lines that go out straight from the center then the answer is mechanical stability the best solution would be to use 2 materials, one with a high and one with a low permeability (=ability to conduct magnetic flux) and make a geometry, where the less permeable material holds the permeable material that would otherwise not be connected to the shaft this however is not economically achievable, so you have small a geometry, where small bridges hold the main material in place

[@benwilms3942]

This didn't explain anything. It was yet another video where the explanation makes sense so long as you already know what's being explained.... defeating the purpose.

[@apdahlen5282]

Fair enough, Ben. I look forward to seeing your video explanation. r/ APD

[@two_number_nines]

someone have any idea how this has anything to do with "reluctance motors can't have good throttle response and have torque ripple"

[@nomoreheroes93]

Yep, torque ripple = uneven power output. However, back in 2011 they realised if you placed permanent magnets in the stator you evened this out, and hence Tesla now using it in the Model 3.

[@NRG1985]

@@nomoreheroes93 rather back in the 1990s beginning of 2000s in the accademia I would say, it's not Tesla related. Strictly speaking it's Tesla model 3 motor is not a reluctance machine. It's an IPM, interior permanent magnet machine which exploit both magnets and reluctance for the torque production. Very similar to Toyota Prius V-shape rotor design.

[@ignaciohavok1]

It’s due to the power factor. Adding magnets makes the current lag less so more real power

[@getartsywithyogita8291]

@@NRG1985 that right. I have been studying on this rear motor and surely will release a video on that. Magnets are used for lower speeds or say cruise speed.. and reluctance torque for higher. speeds.

[@salahosmani2829]

Can I rotate this machine using (three-phase inverter or no ) ????

[@GertStegeman]

Salah Osmani To operate this motor, a special inverter is needed with position encoder feedback.

[@salahosmani2829]

@@GertStegeman i know this in the SRM "salient pole" it sould be use a position sensor and a special inverte. but in the BDFRM there are sinusoidal windings like induction machine. in the stator winding is sinusoidal so i think that there is no a position sensor and there is simple inverter

[@ruke1ire]

subscribed:))

[@ajaysaroj1669]

There is no rotor winding then how ohmic loss possible in rotor

[@PaulAndMuttley]

About 7 years ago I did some work on a switched reluctance motor, but it did not have angular position feedback so it was not very successful. Your video gave me more ideas and maybe inspiration to revisit the idea. I made a video of what I did: kzbin.info/www/bejne/jWevqJ-eqNOHY80

[@josephelmurr1402]

what about torque fluctuations?

[@HermanWillems]

Just cancel them out with anti-torque fluctuation offset generator. :P

[@hole386]

Why is your "F" so wierd

[@th1alb]

your f is the wrong way, it's supposed to look like this -> F / f, what you got there is a 7 at best.
