Thank u sir for good explanation

[@Vikranthreddy777]

Sir,How to calculate starting torque from circle diagram

[@mprathik4885]

sir... angle Pisc should b less than no load power factor angle. in your explanation both angle u have taken as same and also IsN instead of starting from origin u have started from o'

[@surendrakverma555]

Very good lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏

[@EL-ws5vc]

Good afternoon sir, Isn is converted to reference of supply voltage ... Then y instead of drawing Isn value from origin O with phi sc as an angle u have drawn from at tip of Io sir? Pls explain ( @ 11.50)

[@vineethamorris4774]

Goodevening Sir
At time 15:57 sir u have said the explanation for JK=FG; under blocked rotor condn mechanical losses are zero and rotor core loss is max becoz frequency is supply frequency, but under loaded condn rotor frequency is slip freq..so shouldn't rotor core loss decrease such that increase in mechanical losses is compensated by decrease in rotor core loss

[@manishkadwa8657]

Yes you are saying correct thing but the compensation is not a particular function . it is just approximated for practical case.

Sir maximum value of I2' must be V/Z01 rather than V/X01 right ,when s=1 and the variable resistor part is shorted??
Thank you in advance

Please in the video at 8:35, what is Is, Vs, and V1 definitions? I'm a bit confused

[@radhikamajji2810]

how do we draw circle diagram for single phase induction motor??

[@bireshwardas210]

Sir, why maximum torque u r calculating like thia, please provide a proof

[@bireshwardas210]

Sir i got it thanks...

Sir please solve one numerical about circle diagram

@@lecturesinelectricaleng Sir, during blocked rotor, the short ckt current or full current is passed by adjusting Vs. So isn't the short ckt current same as full load current?
