Abstract

U radu su navedena i obrađena postojeća pravila i načini izrade višeslojnih valovitih
namota s profilnom žicom s obzirom na broj utora, polova, paralelnih grana i broj
vodiča u utoru, a sve je objašnjeno na primjerima patentiranih namota. Predložen je
novi skup pravila za izradu namota za primjenu u električnim strojevima s unutarnjim
permanentnim magnetima i pokazano je zašto je taj skup pravila ispravan. Na primjeru
električnog stroja električnog automobila Nissan Leaf pomoću simulacija analizirani
su gubici u hairpin namotu, njihovo ponašanje s promjenom temperature, faznog kuta
i brzine vrtnje stroja. Također, uspoređeni su proračuni gubitaka u namotu između
programskih paketa Motor-CAD i Infolytica MagNet.

Abstract (english)

In the thesis, rules for manufacturing hairpin windings in regards to the number of
slots, poles, parallel paths and number of conductors in a slot are given and explained
for examples found in hairpin winding patents. A new set of rules for manufacturing
hairpin windings is given and it is shown why a winding made by following these rules
is correct. For an example of a Nissan Leaf electric motor, simulations for determining
losses in the winding were made and their dependence on temperature, phase advance
angle and shaft speed are given. Also, calculation of losses in programs Motor-CAD
and Infolytica MagNet were compared.
