We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello. First of all, thank you for your quick response. In the following, I would like to tell you some things that may better understand my problem. I proceeded exactly as per the software example for the constant speed settings. In the software, there is a typical example for a DC brushless motor, which happens to have 4 poles. So I expect to get the same results as when I ran the example. The difference between my model and the example is only an additional rotor and the motor being axial flux. The direction of the magnets is correct according to the electromagnetic field. In the mechanical transient mode, the motor works properly and the results are favorable. This problem appears only in constant speed mode. Is there a way to solve the problem?

With respect and many thanks to you
