Axial-flux machines tend to have cooling difficulties since it is difficult to arrange continuous heat path between the stator stack and the frame. One important reason for this is that no shrink fitting of the stator is possible in an axial-flux machine. Using of liquid-cooled end shields does not alone solve this issue. Cooling of the rotor and the end windings may also be difficult at least in...
This paper investigates the effectiveness of direct oil cooling of a PMSM by modeling flows of coolant inside the machine using Computational Fluid Dynamics (CFD) software. Conjugated fluid-solid heat transfer modeling with anisotropic conductivity coefficients in solids and turbulent fluid flow was performed. The detailed flow modeling allows precise determination of possible cooling approaches and...
Direct water cooling has been used only in large size turbo generators. The method might, however, offer interesting possibilities also in high torque applications. The performance of different cooling fluids for internal liquid cooling of windings is assessed. The arctic operating conditions of machine place special requirements for the fluid thus pure water can not be used for cooling. It is found...
