 Abstract:In order to improve cooling effects of permanent magnet wind generator and reduce the operation temperature, a 3MW permanent magnet wind generator was taken as an example, physical model of three dimensional stator and rotor fluidsolid coupled was established on the basis of the basic assumptions considering ventilation characteristics and structure feature of generator, and the solution conditions was given According to hydromechanics and heat transfer theory, temperature field and fluid field was calculated numerically using finite volume method At the same time, some structures were proposed in view of radial ventilation ducts, and the fluid flow performance and main components temperature of different schemes were analyzed The results indicate that, by reducing the axial size of the radial ventilation duct can effectively improve the cooling performance of the motor The maximum temperature rise in solution was 604K lower than the original one when adopt schemeⅢ
