The paper presents some important results obtained in the thesis performed by mr. Alex Dąbrowski. Basic scientific goal of this paper is to study the negative effect of high temperature on the performance of a photovoltaic power generator and to investigate the influence of cooling on the overall efficiency of the system. The first part covers issues such as benefits, limitations and costs of the...
This paper presents the method for determining losses and efficiency of small axial flux permanent magnet synchronous motor with surface mounted permanent magnets and double external rotor by using measurements. Losses and efficiency are calculated by using measured electrical input power and mechanical output power. The characteristics obtained by the measurements are in good agreement with analytically...
