Abstract

This paper proposes a novel grid-connected to rotor type doubly-fed induction machine (DFIM) in which the rotor winding is connected Lo the grid instead of the stator winding. The stator size and weight of the proposed grid-connccted to rotor type DFIM can be reduced because the proposed type can use rotor core more efficiently compared to the stator type DFIM. In order to verify the size and weight reduction of the proposed type, the loading distribution method (LDM) is utilized. As a design result, Lhc stator outer diameter and weight of the proposed type were decreased. The FEM analysis was also performed Lo verify the design results and to analyze the characteristics of the novel DFIM.
