Hello, I would like to ask, What is the "wireloss" output by the Maxwell plugin in Simplorer? Why is it not equal to the stranded loss calculated in the motor Maxwell model? Why is wireloss like this? What is the reason for this? thanks

Hi

WIRELOSS provides solid loss on the solid windings. If the winding is stranded, WIRELOSS in Simplorer should be 0. The behavior in your screenshot is not expected. Could you let me know what version are you using?

Hi

1、The winding  is stranded. The version I am using is 2024R2. The motor is connected in a delta configuration. Is the simulation result related to the connection method?

2、Using the simplorer-maxwell method，Why is standardloss not equal to 3*I^2*R?

Thanks

Hi,

1. No. I cannot reproduce this weird wireloss in 24R2 version. Is the simplorer model converged?
2. StrandedLoss is dependent on the object’s material conductivity. It represents the loss due to the DC resistance only and uses the cross-sectional area of the object that is assigned with the excitation. It is calculated by 1/sigma*Integration of J^2 over cross section.
