बहुत ही बढ़िया जानकारी दी आपने, हमारे जैसे हिंदी मीडियम वाले लोगो को।

[@pranaychauli233]

I have seen many you tuber to explain same topic but your explanation is at another level. You have a very good concept.👌

[@NitishKumar-yj6yo]

Best explanation on vector control of drive

[@deviprasadpattanaik4634]

nice sensorless vector method teaching ....

[@aforautomation]

thanks brother, keep in touch..

[@ElectricalSATHI]

Thank fou Sir, better explain SVC , if you kind explain about Feedback Vector Control(FVC)
Advace thanks

[@mohnishrajthapa9488]

Sir your way of explanation is great ...request pls add direct torque control method and flux vector control method

[@makardhwajsingh6997]

Dear sir,
Thank you for clearing basic concepts. I want to ask is back EMF will generate from load to VFD in case of speed difference? If yes then what is the calculation of back EMF?

[@sagirmohammad7187]

Nice information . Plz sarvo drive + motor aur servo motor q use krte hain is ki applications pe b vedio baniye .thank you.

[@motivationvideos9293]

Thanks sir

[@oorkruiser]

With closed loop vector control you can also accurately control motor torque above rated nameplate speed.

[@aforautomation]

Yes you are right, close loop vector control performance is best.

[@hukamsingh3191]

Thanks sir g

[@dhiraj-shukla]

Sir,
Please make video on other controlling method of vfd.

[@dhiraj-shukla]

Sir,
Please make video on DTC control of vfd.

[@shashankkumar7770]

How sensorless vector control is determining angle between magnetising current and torque current...how does torque control and slip estimator works..please reply sir

[@aforautomation]

The current which is in same phase of voltage Is called torque current and which is out of phase with voltage is Magnetiging or flux current.drive checks leading angle between voltage and current and calculates torque and flux current separately

[@arpitkhator1990]

Sir har 1 video ke baad 1 video asa banae jisme comments me puche gae problem ka solution de aap..

[@muhamedrasheed3913]

Dear sir,
Can you add closed loop vector

[@hukamsingh3191]

Sir g motor ko quick stop ke liye vfd Emtron me kya parameter dalege yani jese hi limet switch se
Nc se plus no ho to motor attime ruk jaye

[@aforautomation]

uske liye dynamic braking enable karna padega ,aut DBR bhi use karna padega and deccelaration time 1 second dalna padega

[@arunkumar-kd9wi]

Can I increase speed of motor more than its rated using VFD ??

[@aforautomation]

Yes,you can run AM motor more than rated speed,it will run in constant HP zone,means Speed will increase and torque will decrease.you can't get rated torque above rated speed.

[@mayurI4188]

Sir flux vector control pe video nahi banai aapne

[@electricalconcepts7471]

Hello sir ,its very helpful ,sir can you tell me vfd related books ,in which every parameter and its importance is describe and trubleshooting also. Please sir i need them very urgent

[@aforautomation]

You can refer powerflex 700 reference manual,similarly there are technical and parameter manual of all drives you can download easily

Torque control methods used by vfd ka video nahi banaye sir, agar bana hai to link bataye plz

[@rohankhosla2695]

Hello Sir, thank you very much for this explanation in the video.
I have 1 question regarding the sensorless part. My question is how the speed ref is given or how the position of rotor is calculated without sensor?
Thanks in advance

[@okayokokq]

Still looking for the answer

[@aforautomation]

Position of rotor is estimated by using clark and park transformation

[@aforautomation]

without encoder or tacho we can not get rotor position.

[@okayokokq]

@@aforautomation @A For Automation thank u for reply.
recently faced an issue in ABB ACS880 vfd running on estimate/sensorless mode. drive output was on with zero speed reference to the motor and motor was magnetized but not rotating as ref was zero. But drive was showing -50rpm estimated speed.
Only cause found out was that motor brake didn't open(jammed) during magnetization and rotor was not free.

[@okayokokq]

Question here is, how does a jammed rotor affect stator/magnetized current when there is no speed reference.

[@mubarishussain3696]

Why Sensorless can t be used to control Torque. Since we are able to change Torque producing current. Can you please explain to me . Thanks for the videos

[@aforautomation]

to control the torque drive need to know and rotor position to keep the stator flux position at 90° with respect to rotor flux.to know the exact position an encoder is required and in sensorless vector we don't use encoder thats why it is not possible to maintain torque in sensorless vector.

[@mubarishussain3696]

Thanks for the answer. Appreciate it

[@hukamsingh3191]

Sir g coast to stop parameter dalne ke baad acceel time or deceleration time work krega ya nhi.

[@aforautomation]

accel time work karega.. decell time stop k time pe kaam nahi karega..lekin agar running condition me speed reference kam karoge to decell time kaam karega...

[@kejriwallover9994]

Isi liye engeenier ko 11000 me superviser ya quality me kam karte h

[@kejriwallover9994]

Are sidha sidha bataiye ki vector mode select karo ge to 20Hz frequency range me 90% speed se motor chalegi
Aur frequency scaler mode me 20Hz me output 20% tak mil sakta h

[@hukamsingh3191]

Nice sir g

[@aforautomation]

thanks brother

[@moriyogesh2646]

Yaskava vfd pe video banaye

[@ranjanpal7217]

Good explanation..
Does V/f also remains constant in vector controlled VFD ?
i.e. if a motor which is rated as 460V/60Hz is made to run at 30 Hz, does the voltage still remain 460V ?

[@aforautomation]

In vector control drive v/f ratio is not constant it will vary as per torque/speed requirement.

Agar coast to stop karoge to motor jaldi se nahi rukega aur electrical braking kaam nahi karega sirf mechanical brake se rukega motor
