I have designed an Induction motor - 3 phase, 4 pole in Rmxprt and then exported the model to Maxwell 2D. I have noticed that Maxwell solves the model in fractions and solved my model in 4 fractions.

When I check my excitation values of the stator winding, the resistance value remains same as in Rmxprt solution data, but the Inductance value has been divided by 4. Is it because Maxwell solves the model in fractions? And if so why isn't it the same for resistance value as well? I have attached the picture of the same.

Hi Dharani Moka,

The inductance mentioned in the winding details of Maxwell 2d is the end leakage inductance and not the total phase inductance. If it is a 3D design you need not input this inductance value.
This is indicated at the end of the design sheet under “TRANSIENT FEA INPUT DATA” in RMXprt.

I checked it with the inbuilt example and the same data is transferred to Maxwell.

 

You can refer to the below forum thread for additional information.
