Rotor core punching

Rotating machinery can withstand significant centrifugal force during operation. Therefore, the strength of a rotor punching should be analyzed. This problem was solved using Workbench. Considering the periodicity of the rotor punching and load, a 1/8 model was created and cyclic symmetric boundaries were defined. The model consists of a rotor punching plate and magnetic steel. Frictional contacts were applied between the rotor punching and magnetic steel. In the end, the results of the 1/8 model were expanded to show the results of the full structure.
