Hello everyone
I simulated the eddy current brake of 2 1000-turn coils with 5 amp excitation in Ansys Maxwell, but the torque fluctuates. How can I overcome this problem?

Is the brake disc mechanically vibrating? If so, make it stiffer.

The disc rotates from its center, I don't think there is anything that could cause vibration.

Since it's a simulation and really rotating from the center, then it must be a numerical error.

Try smaller time steps (probably the easiest).

Also, the disk diameter may need to be either an odd or even multiple of the grid resolution; depends on whether the software treats Points as vertices or centroids.

What causes torque fluctuations in Ansys Maxwell simulations?

Torque fluctuations in Ansys Maxwell simulations can be caused by several factors including mesh quality, time-step size, material properties, and boundary conditions. Ensuring accurate representation of these factors is crucial for minimizing fluctuations.

How can I reduce torque ripple in my Ansys Maxwell simulation?

To reduce torque ripple, you can refine the mesh, optimize the time-step size, use accurate material models, and ensure that the boundary conditions are correctly applied. Additionally, smoothing techniques and advanced solver settings can help mitigate these fluctuations.

Why is my Ansys Maxwell simulation showing unrealistic torque values?

Unrealistic torque values can result from incorrect material properties, improper boundary conditions, or numerical instabilities. Double-checking the input parameters, refining the mesh, and validating the simulation setup against known benchmarks can help address this issue.

What post-processing techniques can help analyze torque fluctuations in Ansys Maxwell?

Post-processing techniques such as FFT (Fast Fourier Transform) analysis, filtering, and statistical analysis can help in understanding and quantifying torque fluctuations. Visualizing torque over time or frequency domain can also provide insights into the sources of fluctuations.

Can co-simulation with other Ansys tools help in addressing torque fluctuations?

Yes, co-simulation with other Ansys tools such as Ansys Mechanical or Ansys Fluent can provide a more comprehensive analysis of the system, helping to identify and mitigate the sources of torque fluctuations. This integrated approach can lead to more accurate and robust simulation results.
