A Study on the Stress Distribution in Rotor Core inserted with Cu bar

Rotor에 대한 Cu-bar 압입시 응력분포에 대한 연구

In this study, main works are focused on investigating the stress distribution at the interface between a rotor core and Cu bar when a punch is applied into the body of Cu bar. A parametric study with dimensional changes of core slot was performed numerically to identify what factors are dominant in producing high contact forces in the interface. As analysis results, it was found that core slot length was a dominant factor in increasing contact force at the interface between a rotor core and Cu bar.
