You will find at the end of the article a video presenting these new features.

TIGHTER INTEGRATION OF FLUXMOTOR & FLUX

FluxMotor is often used at concept design phase of electric machines to explore the design space, trying different topologies and configurations in a very easy and fast way. For more in-depth studies, exporting the model to Flux is the natural next step. With the latest version, this is only a few clicks, the Flux model is created and opened in Flux directly from FluxMotor.

MORE ACCURACY WITH NEW COMPUTATIONS OF LOSSES

FluxMotor has now the option to compute AC losses in windings and in permanent magnets, in order to have a better evaluation of the efficiency of the machine on specific working points. For such calculations, transient finite-elements studies are performed. Depending of the level of details you want to get, only one phase or all phases can be represented. When using these options, the variations with time of various outputs, like the torque, the flux density in the airgap or voltages and currents can be displayed.

HAIRPIN WINDING MODELING

Known as a solution to obtain better slot fillings and higher power densities, hairpin windings are quite popular, especially for traction applications. When virtually designing your machine in FluxMotor, you can now consider such winding configurations. The winding tool will help you visualize directly the winding architecture and the slot filling. Winding analysis tools like winding factors or “slot star” diagrams are also available. The whole definition can then be exported to Flux to run computations. A great speed-up for Flux users to model hairpin windings !

MORE ON THERMAL COMPUTATIONS

For synchronous machines with permanent magnets with inner rotors, you can now export a ready-to-solve project to Flux for performing a 2D thermal steady-state computation, based on a set of losses and a speed. It allows getting a precise view of the temperature distribution into slots and get insight on what improvements can be done to have better heat transfer towards the stator.

Many other improvements have been brought to the version, including an optimization of the memory and CPU usage when dealing with files with many results. You can discover all the details by reading the complete Release Note document

Hi, 

for the next release it would be very nice if, among the parameters calculated, the motor volume (with the diameter and axial length) and the Torque per volume are also calculated. That way, once you export it to Hyperstudy you can set a goal which is to maximize the torque per volume which is a very common goal when designing motors. 

Thanks.
