Sir, thank you so much Really I felt very very happy .I am struggling with this topic U completed perfectly with in 15 mints . Thanks a lot sir, Careful from Carona also sir

And sir if u have neglected shunt branch parameter, that means voltage is at reduced level. Nd if voltage is at reduced level, than how the s.c current can be high to damage the winding

Good explanation sir. Thank you

Sir, why should the autotransformer ratings be greater than the motor ratings, should it be used for starting the induction motor?

As the torque at the starting is 25 to 64 Sfl times full load torque which is very higher ....so why do we say that squirrel cage motor have low starting torque
@rajatgupta14744 жыл бұрын
Squirrel cage rotor will haive high starting torque than slip ring, if we dont add extra resistance to to slipring motor. Than torque will be inveresly proportional to reactance, and slipring rotor has high reactance than cage, therefore starting torque will be low, in this case.

Sir in starting of video, why didnt u added shunt branch parameter in equivalent circuit. We r not doing blocked rotor test so we didnt reduced the voltage, why u neglected shunt branch parameter

in case of reduced voltage reactance method, the power factor is decreased, if the power factor decreases it is going to effect the efficiency of the machine, but you said efficiency remains constant, why is that?

Isnt the autotransformer method very expensive as it requires the purchase of an extra machine?
