Hi,
I have been given the following information for the question the motor is a 50Hz, 8 pole induction motor with 4% full load slip. Rotor resistance is .001Ω per phase and a stand still reactance of .005Ω per phase.
I need to find the ratio of max to full load torque
I have been able to work out a few things for the problem but I have been looking at it now and not sure what the next step is.
I want to find the torque but the formulas need either a voltage, EMF or a current. I think that I am heading in the right direction just need a push.
The working so far are in the attachment.
Thanks for your time
