What is the benefit of infinite box?
What are the equations to find end wending resistance, end wending inductance, end ring resistance and end ring inductance for single phase induction motor?
Thanks.
Hello Zainab;
Thank you for your email.
For the end winding resistance, if you know the phase resistance, I prefer to put this value directly on the coil component definition.
For the end winding inductance, end ring impedance you may use Trickey Fromulas. You can find them from the tutorial for three phase induction motor available from the Flux supervisor in SKEW.

Hello farid;
thank you for answer,
what is the factors make the result of torque error?
Thanks
You are welcome !
I Don't understood your question, can you please add more clarification?
Regards
I designed single phase induction motors and the result of values of the torque is very small the correct value for one motor is 3 N.m but the result is very small in the flux and the other motor the value of torque should be 3.5 N.m but the same problem the result of value given from altair flux is very small, so i ask about the reaons make the value of torque error
thanks
For single phase induction machine one has to use Transient magnetic application, are you using it ? The AC Steady state application is not adapted for this kind of motor.
The second point, is to take care on the computation of inter bars impedance, normally the Tickey formulas estimate well this impedance.
The third point, is the material magnetic characteristics, are you using the good ones ?
You said that you designed a motor, do you have already the prototype and you are comparing Flux results to measurements ones? Or Flux results are compared to analytical computation?
Please share your Flux project if you still have this différences.
