This paper performs optimization of permanent magnet clutch shapes with
the following objectives: maximum tangential attraction force and
minimum volume of utilized materials. To form optimal shapes, the points
on the clutch surface are chosen as optimization parameters. The
optimization is carried out using Ārtap framework in connection with
COMSOL software, where the 3D model of the clutch has been created.
After the optimization, the tangential attraction force has increased by
13% and the volume of the clutch has been reduced by 24%.
