Markovic, M.Saunders, L.Perriard, Y.2007-11-282007-11-282007-11-28200610.1109/IAS.2006.256520https://infoscience.epfl.ch/handle/20.500.14299/15022The paper presents a methodology to determine the coefficient of the natural convection for the surface of a small electric motor. The theory of natural convection is applied to obtain analytical formulas, and the radiation is incorporated in the model. The measurements are performed on a simple motor model, a copper cylinder with a resistance inside acting as a heater. The obtained results match the theoretical predictions. © 2006 IEEE.text::conference output::conference proceedings::conference paper
