Induction Motor #4 - Electrical frequency at the Rotor

Let us discuss what is the frequency of the induced emf at the Rotor...

Man, you are really good at explaining things! Thanks alot!

[@tharindumaduwantha1023]

I will never forget it because of your example ..thankyou very much for your great job..❤️❤️

[@yuna2799]

Thank you so much, sir! The way you explain was really something. Was looking for a video like this for a long time. Please keep explaining every single topic in this way. That's gonna help us a lottttttt. THANKS!!

This was funny and informative! Made my morning. Thank you, love from Texas!

Jyoti dada,, I also Can't believe that one community of your country ar roaring about NRC to execute CAA as CAB & You are watching this valuable video only for Learning,,,, YOU countrY is misterious,,, Love from🇧🇩🇧🇩🇧🇩🇧🇩BangladeSh

[@akashjai309]

Crystal clear lecture... 👌👌😐 Thanks alot sir

[@bhaskarrao5254]

Ultimately the locals had fun....lol

[@sagarjatoi2446]

Ur lectures boost my interest in this subject love u from pakistan

[@ElectricalisEasy]

thank you

How is the frequency of EMF defined? Is it the frequency of the current within a closed loop conductor in a rotor or is it related to anything in the rotational direction? How is then the induced magnetic field by the EMF defined?

[@OssamaEnnaki]

Love the boy slapping example, very well explained sir thank you.

[@yaserc.3363]

poor guy 😂😂.......many thanks for Crystal clear explanation

[@adibmd.ridwan]

Sir first I thank to you for your great contribution in electrical engineering. Here I have a doubt in an topic of this.please ans me. If rotor electrical frequency (fr) = (Nsync - Nm)*p/120 and rotor mechanical frequency (fm) = Nm*p/120 then Why we use rotor electrical frequency instead of rotor mechanical frequency?

[@ElectricalisEasy]

Rotor mechanical frequency? We use electrical frequency bcz that what influences the synchronous speed of field...and please put a time stamp for the doubts..otherwise it is very difficult for me to watch the entire video...

[@ElectricalisEasy]

And rotor electrical frequency is electrical supply of the rotor windings, that is what we are interested in...

[@adibmd.ridwan]

In the last part of video , you solve a math. There we use w(m)=2*pi*N(m)/60=179.07 rad/s. but you do not use w(re) w(re) = 2*pi*f(re)=18.84 rad/s so they are not equal....... >>then I want to know what is the difference between w(m) & w(re) ? >>Is there present any term rotor mechanical frequency(which is related with w(re)) ?

it was very helpful . you are great sir.

[@ElectricalisEasy]

Thank you so much...also.do consider sharing the videos with Ur friends and anyone who.might find the videos helpful

[@rishikalalwani1675]

Here when you talk about the standstill condition so the frequency of rotor = electrical frequency . So does that mean the rotor will have the mechanical speed of stator? If that is so, then the rotor should not rotate. Time = 13:20

[@ElectricalisEasy]

Standstill means the rotor speed is zero, it could be at the moment of starting or In a Blocked rotor condition

[@rishikalalwani1675]

@@ElectricalisEasy Then if the speed of rotor=0, how is the frequency of stator =frequency of rotor. Which frequency are you talking about.Mechanical or electrical? I'm a bit confused! And thanks for replying!

[@ElectricalisEasy]

electrical frequency

A lot of respect from us sir. But what motivates you to share free awesome educational videos , because now a days most of the paid professor teach with no interest. Paid professor of our university : "Students complete this tutorial sheets , you will pass with O grade"

Great content

[@alaminchowdhury5096]

Thanks a lot, sir.

[@sagarjatoi2446]

Sir is this rotor frequency or rotor current frequency

[@hriday1943]

you show here that,the rotor speed is clockwise,but in the AC Machinary fundamentals lectures you show that rotor speed direction as per as stator magnetic field speed direction and that is counterclockwise

[@suryaprakashmishra1599]

respected sir i have a query what is air gap speed wrt to different part in a induction motor please help i am bit confused in inverted induction motor

[@ElectricalisEasy]

I am not aware about the terms air gap speed..are u meaning the speed of rotation magnetic field?

[@suryaprakashmishra1599]

@@ElectricalisEasy actually this is a question from ps bimbhra book sir rotor of a 3 phase SRIM fed from 3 ph balanced supply with stator winding short circuited syn speed is Ns if rotor rotates cw with speed Nr then 1-speed of air gap field wrt stator is Ns-Nr ACW 2-speed of rotor produced field wrt stator is Ns+Nr ACW 3-speed of air gap field wrt rotor is Ns cw

For Wm if I use Wm=2 x pie x Fm I don't get the answer why is this? Evwn though the formula for angular frequency W is W =2xpiexF
