Abstract
This paper suggests the new PMSM design that can reduce leakage magnetic flux. Through adapting non-magnetic frame structure, it decreases leakage magnetic flux on the rotor's rib and web structure. And with this, it increases power density of the motor. To verify the effectiveness of the new design of rotor compared to the common type, through small sized real model's test was conducted. To obtain final model, structural FEM analysis was also used for structural stability. Additional loss generation problem that can occur in the new frame structure was checked with the 3D FEM analysis.
