In this paper, the finite-element method (FEM) based on 2-D numerical analysis was used for the basic design and characteristics analysis of a small-scale 3-kW wind power generator to which a permanent-magnet generator was applied. A prototype was manufactured, and a characteristics experiment was performed to verify the designed generator. In addition, the optimization design in order to satisfy...
In this paper, we developed stator and rotor shapes of interior permanent magnet type brushless motor for automotive cooling device in order to obtain better performance than the prototype. Response surface methodology (RSM) is employed in this paper as an optimization method. Finite element computations have been used for numerical experiments on geometrical design variables in order to determine...
This paper dealt with the design and analysis of the outer rotor type interior permanent magnet synchronous motor (IPMSM) for an electric bicycle. To reduce cogging torque in IPMSM, we designed the optimal shapes of rotor core and magnet. Using the finite element method (FEM), performances of the proposed motor were analyzed and compared. The prototype motor was made for verifying the actual performance...
