Analysis of cooling of electric motor by radial fan; realization of the experimental analysis of CFD

It is shown by this paper, that flow analysis of fans and fan covers of different geometries are studied.  Good thermal management reduces the temperature rise in motor and increases motor life. A temperature drop of 10 degrees can extend the engine electrical insulation life by a factor of two.[1] To determine the optimal geometry of the fan and fan cover, as well as evaluation of its effect, the analysis was performed at a certain flow volume. The purpose of this research is to simulate the cooling state of an induction electric motor that does not yet have a prototype. To correlate the analyzes with real experiments, the velocity of inlet was used as a parameter. Experimental results can be used for designing induction electric motors and for optimizing aerodynamic performance.
