[mahibest]

The way you teach Machines is amazing. thank you Sir.

[MJ_Suresh]

One of the excellent teacher I have ever seen sir 🙏🙏🙏

[Venu_Gopal]

Clearly explained sir, thank you so much, all my doubts are cleared

[surendrakverma]

Excellent lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[alphaelectrical]

Sir i love your reaching. Because you i love now machine. Thank u sir.

[kumarkvrs]

thank you very much for clear explanation

[ujjallaha]

Please make video on
1. Magnetic circuit.
2.magnetic saturation.

[kvenkateswarlu]

What is the output of the Asynchronous Generator ...?

[prabinmishra]

Can we get hand out of above presentation.

[reshabdasrajak]

Amazing sir.. thanks for the great effort.. Waiting for more such interesting videos

[ManishSaini-xdbp]

Sir everywhere voltage control method is denoted as series parallel control method

And you tell us that method (series parallel control) is paralleling feild coil method

[jyosnaramulolla]

In case of flux control method why the flux cannot be strengthened .Can we use flux control method for below rated speeds?

[vamsimouli]

Sir small doubt in flux control method

Power constant

It is electrical power or mechanical power

Please tell me sir

[Nameless-lsjb]

Sir in series motor field diverter the relation between Speed, back emf and Ia and Ise
N2/N1=Eb2 *Ia/Eb1*Ise afthis this u wrote
N2/N1=Eb2*Ise/Eb1*Ia
After this i got really confused?

[anwesh]

is torque and speed in case of motor is produced due to back emf and incoming current respectively

[DhananjayKumar-bydm]

At 11:48
In series field control (Ise= Ia ) As No of turns increses, is there any effect on Ia, , or Ia remains constant as it depend only on load

[saiadapa]

Sir, ward leonard method is used for which type of dc motors(shunt, series, compound)

[anwesh]

Sir, in case of motors is direction of torque Opp to the direction of motion

[moinshaikh]

4:41 Dear sir
I was not able to process speed being inversely proportional to torque so i developed this algorithm, is it correct?
Torque ~ current*flux
flux ↓
Torque ↓ thus deceleration -dn/dt
speed ↓
Eb ↓↓ ~ flux*speed thus double decrease
current linearly proportional as function of V-Eb/Ra
Torque ↑↑
speed load torque remained undisturbed

[saikumar]

Sir why voltage speed control is not used for shunt motor
