ANSYS Maxwell: Create 3D Axial Flux Motors

In this video, I'm going to show you how to create a 3D axial flux motor model in ANSYS Maxwell. Once you open AEDT, create a new RM Expert model. From here, you need to select Generate RM Expert Solutions. And under Synchronous Machines, select Axial Flux Motor.

And a new RM Expert model will be created. This is the one that I previously created. Then go to Machine; here you need to define the air gap length. I use 1mm in this example. The double-sided here is none, which means it is a single rotor single stator AFM.

Users can also select double stator or double rotor. Then we define the parameters for the stator. Number of poles is 8, number of slots is 12, circuit type is default, which is 3-phase Y connection. The slot type is 1. Those are the parameters for the slot that users can change.

Then we go to the stator core: Outer diameter is 100mm, Inner diameter is 60mm. The length is 30mm. This length is the axial length of the stator core. The material here is M 19. Then we can define the slot parameters. I selected a parallel tooth stator. The tooth width is 8mm.

And the other parameters; users can define them based on the actual applications. Then the last part of the stator is the winding. I used a two-layer winding. The parallel path is 1. Coil pitch is also 1. The material of the conductors is copper. I used the default values for everything else.

For the rotor, first we define the number of poles. It is the same as we previously defined for the stator, 8. For the core, it is actually the rotor back iron. In this example, Magnet type is the magnet material selected by users. Magnet length is the radial thickness of the magnet.

So if OD is 100 and ID is 60, the radial length will be 20. Users can also choose a different number, for example, 30, then the magnet will be longer than the back iron. I'm going to use 20mm here. Magnet thickness is the axial thickness of the magnet. We can leave the shaft parameters as they are.

After everything is defined, we need to right-click analysis and add a solution setup. Once a solution setup is added, we can put some random numbers here as long as they are non-zero. After that, right-click it and analyze it. This will just take a few seconds. Once solved, right-click Setup again.

There is an option called Create Maxwell Design. Users can choose to create a 2D or 3D model. In the example, I'll create a 3D model. Then a partial 3D model will be automatically created in Maxwell. It will take just less than a minute. Now the model has been created successfully.

You can view the model, and it is a partial model. You can also check the boundary conditions. Also, this model is ready to run. You just need to right-click setup and click analyze. If the user wants to create a double stator AFM, simply choose double-sided rotor in RM Expert.

Then just repeat the process again, solve it, and create a 3D Maxwell model. Once the model is created, you can take a look. You will see that it looks very similar to the one that we just created. However, if we check the boundary conditions, the symmetry boundary condition is added to this model.

This boundary condition makes it a double stator AFM. If you have any questions, please contact us at https://ozeninc.com/contact for more information. Thank you for watching.
