Comparison of Two Types of Cooling of Axial Flux Permanent Magnet Machines by CFD Simulation

This paper is focused on the comparison of two types of possible cooling of the stator of the axial synchronous machine with permanent magnets. The main contribution is the specification of basic issues of the cooling of axial machines. This comparable study is presented the evaluation of suitability as a comparison of two axial flux machine configurations for specific duty cycle. The CFD analysis of the flowing coolant is used to determine the wall heat transfer coefficient.
