Does the Torque output already account for internal losses in 2D transient magnetics in Simlab ???

Hello Community,

I have recently completed a 2D Transient Magnetic simulation in SimLab for a high-speed motor. My goal is to determine the final output power, but I am seeking clarification on how the flux solver handles different loss components in relation to the calculated torque.

Setup & Results:

• Software: SimLab 2D Transient Magnetics with flux solver
• Calculated Losses: I have extracted data for Stator Iron (Statorblech), Magnet Eddy Currents (passive solid conductor), Rotor Iron, and Copper losses.
• Torque Output: The solver provides a torque value.

I have two specific questions regarding the transition from Electromagnetic results to Mechanical output:

1. Does the Torque output already account for internal losses?

In a 2D Transient Magnetic context, does the software’s reported torque already "subtract" the iron losses and eddy currents in the magnets/conductors? Or is the reported torque purely the electromagnetic interaction, requiring me to manually subtract the power equivalent of these losses to find the actual Shaft Torque?

2. Is there a way to include these "rotating vs. fixed" airgap losses directly within the Magnetic simulation?

Till now in the simulation i have not considered the airgap losses. now i am planning to calculate that also. How can i calculate the losses in Airgap??

Thanks in advance

Hi,

The computed torque in case of Simlab doesn’t considers the losses. Sam principle as in Flux. But if you want to consider the losses you can do it. Once the torque is computed and all the losses computed you can use the formula to compute the torque considering the losses.

Thanks.
