Abstract EN
A comparison between different analytical and finite-element (FE) tools for the computation of cogging torque and torque ripple in axial flux permanent-magnet synchronous machines is made.
2D and 3D FE models are the most accurate for the computation of cogging torque and torque ripple.
However, they are too time consuming to be used for optimization studies.
Therefore, analytical tools are also used to obtain the cogging torque and torque ripple.
In this paper, three types of analytical models are considered.
They are all based on dividing the machine into many slices in the radial direction.
One model computes the lateral force based on the magnetic field distribution in the air gap area.
Another model is based on conformal mapping and uses complex Schwarz Christoffel (SC) transformations.
The last model is based on the subdomain technique, which divides the studied geometry into a number of separate domains.
The different types of models are compared for different slot openings and permanent-magnet widths.
One of the main conclusions is that the subdomain model is best suited to compute the cogging torque and torque ripple with a much higher accuracy than the SC model.
