magneto thermal study for PMSM using Altair HyperWorks

Wahbi Ben Ismail

Hi,

I want to do a coupled magneto-thermal analysis of PMSM for EV. Please, it is possible to do it with Altair HyperWorks ? Can I import the 3D geometry from FluxMotor and apply all the physics in HyperWorks ?

Thank you !

I know this doesn't quite answer your question, but I recently hosted a webinar where we couple drive currents from PSIM (power electronics solver) into Flux for better losses calculation of the motor.

The currents from PSIM were harmonic rich with the conduction drop for switch or body diode, dead time, switching speed. etc. They were driving the flux lookup table model in PSIM which then gives a very tight correlation between the operating point in PSIM vs the same excitation in Flux.

We also have another webinar coming up using Simlab/electroflo for thermal of the inverter on June 22

Hi,

You can start from FluxMotor and generate a 3D geometry that can be used to compute the losses in Flux. You can then compute the losses and send to our CFD solver using SimLab.

Hi,

In addition to HyperWorks, you can also do the multiphysics modeling and analysis for electric motors in SimLab. Please refer to the following Altair KnowledgeBase article for more details.

The previous article is realized with SimLab 2022.2. The content is updated with SimLab 2022.3 and it will be presented in an upcoming training session (eMotor Multiphysics with SimLab). Please find the registration link at the end of the article.

Hi,

Thank you for your answer. 

And it's possible with HyperWorks please ? I didn't found a tutorial that I can follow.

Thank you,

Hi,

At present, we have not produced any tutorials for magneto-thermal coupling analysis for electric machines based on HyperWorks. But this does not necessarily mean it cannot be implemented. The critical point of the one-way coupling is to calculate the loss distribution (Joule losses and iron losses) in the electromagnetic analysis, which will be further used in the thermal analysis as the heat source of the motor.

If the HyperWorks you are referring to is HyperMesh, please check some thermal tutorials of HyperMesh for more details.

Regarding the magneto-thermal coupling analysis for electric machines, it is more recommended here:

1. FluxMotor. A fast motor design tool. With some basic multiphysics capabilities, we can not only predict the electromagnetic performance of the motor but also optimize the cooling strategies and the NVH performance. 

2. Flux. In fact, for this kind of problem (magneto-thermal analysis), we can also complete it directly based on Flux (including the coupling of 2D motors and 3D motors). You can refer to two example in Flux for more details:

Flux 2D:

Flux 3D:

3. SimLab. As mentioned before, the best solution is to do the magneto-thermal analysis in SimLab, a process-oriented multidisciplinary simulation environment. In this case, Flux will be used for the electromagnetic solution, and AcuSolvefor thermal solution (or the CFD solution).
