Sir,How to calculate starting torque from circle diagram
@mprathik4885 Жыл бұрын
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'

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

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

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)

4:58 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
