چکیده

Operation of any kind of machinery is always connected to efficiency and losses. The part of energy is always being dissipated to the surroundings. In the case of electric machines the losses result in heat generation. Present contribution introduces the numerical method for predicting and analysing the heat transfer including conduction, convection, and radiation at the specific operating regimes of electric motor. For numerical method validation, experimental system was used. The goal of analysis was to define the mathematical model for proper definition of heat transfer mechanisms. Streszczenie. Wszelkiego rodzaju działanie z urządzeniami związane są ze sprawnością i stratami. Część energii jest rozpraszana do otoczenia. W przypadku maszyn elektrycznych wynikiem strat mocy jest generacja ciepła. Artykuł przedstawia metodę numeryczną dla predykcji i analizy przepływu ciepła, włączając przewodnictwo, konwekcję i promieniowanie w specyficznym obszarach pracy silnika elektrycznego. Dla walidacji wyników użyto systemu eksperymentalnego. Celem analizy było zdefiniowanie modelu matematycznego dla właściwego opisu mechanizmu przepływu ciepła.
