Thermal properties are a key issue in many applications associated with electrical machines. Because of its special configuration, an axial-flux electrical machine usually uses self-ventilation. However, this cooling method has a significant impact degrading the machine operating characteristics, and thus, an independent cooling system is desirable. The focus of this paper is on the steady-state thermal...
Thermal modeling of a 100 kW radial flux permanent magnet electrical machine is studied and verified by experiments. The traction machine has hybrid cooling. A simplified thermal model based on Computational Fluid Dynamics (CFD) was used to analyze the temperature distribution throughout the machine. The machine has a water jacket and adopts potting materials around the end-windings. The potting materials...
