Meritve karakteristik elektromotorja za pogon električnega vozila

This paper aims to present the performance and measurement results of a load test performed on a brushless DC motor built into the wheel of a solar-powered vehicle. A brushless DC motor\u27s theoretical background and operation are presented at the beginning of the paper. The article covers the technical specification of the solar-powered vehicle and the inbuilt brushless DC motor. The measurements were performed with the described equipment at the Institute of Energy Technology, Faculty of Energy Technology, University of Maribor. Due to the unique design of the measured electric motor, it was also necessary to make a special housing, which was intended for connecting the electric motor to the test bench. The article concludes with an analysis of the measurement results in comparison with the data provided by the electric motor manufacturer.Cilj prispevka je predstaviti izvedbo in rezultate meritve obremenitvenega testa enosmernega brezkrtačnega motorja, ki je vgrajen v kolo solarnega vozila. V začetku prispevka je najprej predstavljeno teoretično ozadje zgradbe in delovanja enosmernega brezkrtačnega motorja. Prispevek zajema tehnične specifikacije solarnega vozila in vgrajenega električnega motorja. Meritve so bile opravljene s predstavljeno opremo na Inštitutu za energetiko, Fakultete za energetiko Univerze v Mariboru. Zaradi posebne izvedbe merjenega motorja je bilo potrebno izdelati tudi posebno ohišje, ki je namenjeno priklopu motorja na merilno mesto. V zaključku je podana tudi analiza rezultatov meritev v primerjavi s podatki, ki so bili podani s strani proizvajalca motorja
