I work in EV startup in Bay area! I had all qns about regenerative braking mathematical modelling for near 0 speeds!
I am happy to say this video is really useful to understand the fundamentals
Thanx !!
Thanks for sharing
Superb explanation in an easy way.
Zaad, this video is excellent! I watched the whole thing. I took an electromechanical design course a few years ago and this was the perfect refresher on induction motors. Thank you!
We are glad that you liked it. That is why we made it for. We would love to hear more from you. Hit subscribe and start Learning more.
Sir please 3- phase induction motor kya pura series provide kijiye sir🙏🙏🙏🙏
Super explanation sir❤❤
Beautiful explained Sir .
Excellent explanation!
How is it possible...to give and take electrical energy through the same cable?
Regenerative braking is possible in Synchronous motor? Is is possible in Permanent magnet synchronous motor?
PMSM very nicely supports regen braking.Some of the current EVs uses this motor
What an explanation sir.
Glad you liked it
Pl explain why negative torque produced during regeneration?? Its not just about equation that current will be reversed in regeneration. How current will be reversed must be explained
If you ask about the basics then since it is generating power while breaking the current will move away from the machine towards the source, now due to generation effect the machine will demand torque instead of supplying like generators do.
when we change synchronous frequency, doesnt it change rotor frequency too? and won't that be a problem when we are making a VFD with regenerative braking
Yes the rotor frequency will be changed too. Imagine a scenario when we leave the accelerator of a EV the synchronous frequency will be reduced, since the rotor was running it will take some time to slow down and to reach the decreased synchronous frequency. The motor will regenerate only till both frequencies get the same value.
Most of the industrial VFD uses external rheostats to dissipate this energy but options are also there to use it back to source or to batteries.
Hope that solves the query
Good explanation...sir
Bahut mast
U have explained it very well and can u plz explain regeneration in hoist applications ??
I Will Try to Do It Soon
Sir What about back emf where it will go
What is the safe maximum and minimum speed limit at which regenerative braking can be applied in electric train? If supply frequency is to be lowered to maximize regeneration, then what is the limit of minimum frequency that can be lowered from 50Hz?
Every Traction company has a different limit but on average Regen Braking can be applied at speed above 20KM/HR below this mechanical break will work. The frequency will be lowered up to 12HZ to get maximum generation some companies go below that also.
@@zaadlearn5500 Thank you for answering. Is there any document which i can use for reference regarding low frequency limit?
@@dilshangunatillake5336 No Companies generally never share that kind of documents
With the help of regenrative breaking we can't down our speed to zero
.. Ryt sir????
Yes we Can't we have to use a Mechanical Brake at the end.
@@zaadlearn5500 in Indian rlwy... Instructions given to us for using regenrative breaking to get zero speed...
As I'm from electrical engg background so i asked them but they still saying 0 speed😂
Why we use braking resistor in VFD
I have a problem in offset printing machine mitshubushi drive FR-Z220 15 KW e.ovt fault what is the reason
What is the Error Code
hiii how do we reduce the frequency
By Using Cyclo Converters or Inverters
What language is this?
