- Abstract
- This paper deals with the temperature prediction of wound rotor synchronous machine (WRSM). A thermal equivalent circuit of WRSM is proposed with considering oil-cooling system in order to shorten the analyzing time. Copper loss and core loss those are main heat source of WRSM are calculated by numerical method. In this paper, 3D cylindrical motor model is replaced with 2D equivalent radial and axial directional model. The thermal equivalent model is represented by the thermal resistances and thermal capacitances, which are determined by motor configuration. In order to verify the thermal equivalent model a temperature test in a 120kW WRSM conducted
