This paper presents a time-harmonic coupled field analysis method to calculate the eddy current, loss and temperature fields in the end region of a 15MW hydraulic generator. The magnetic-thermal coupled field under different operating modes are calculated when the clamping finger is made of carbon steel and stainless steel respectively. The distributions of eddy current loss and temperature in the clamping finger show that the highest temperature of the clamping finger is far below the limiting temperature of the insulation. The material of the clamping finger should be selected as carbon steel when considering the manufacturing cost.
