Abstract

With the volume of induction motor in ship domain for driving application´s increasing, the thermal load needs such bigger than ever before that electric machines are experiencing higher temperature which can affect performance and life expectancy in small room. The efficiency cooling system^[1] is essential to keep induction motor operating regularly. The Y2-250M-455kW fan-cooled induction motor is taken as an example, and the steady temperature field is calculated by the finite volume method^[2]. On this basis, the characteristics of fluid are analyzed in detail, as well as the different parameters of fluid in different positions can be shown. Finally the results of fluid field and temperature field, which are to be verified, are reasonable according to the measured data.
