In this paper, a validated numerical model was introduced to determine the temperature and velocity fields outside the electric motor. The analysed object was a brushless permanent magnet motor (PM BLDC) having a rated power of 431 W with neodymium permanent magnets located on the rotor. The temperature and velocity measurements were conducted using thermocouples and constant-temperature anemometers. The numerical model covered the investigated motor and the same unit working as a generator and the air volume around them in order to improve the heat dissipation conditions. The numerical results show a satisfactory agreement with the values obtained during the measurements.

W pracy przedstawiono zwalidowany eksperymentalnie model numeryczny do wyznaczenia pola temperatury oraz prędkości na obudowie oraz wokół bezszczotkowego silnika elektrycznego małej mocy. Pomiary temperatury i prędkości przeprowadzono na stanowisku badawczym za pomocą termopar oraz anemometrów stałotemperaturowych i posłużyły one do walidacji modelu. Model numeryczny obejmował silnik wraz z obciążającą go prądnicą oraz bryłę powietrza wokół obu maszyn w celu dokładniejszego odwzorowania warunków wymiany ciepła. Wyniki otrzymane z modelu numerycznego wykazały satysfakcjonującą zgodność z wartościami otrzymanymi podczas pomiaru.
