Abstract

U ovom diplomskom radu proveden je analitički izračun i 3D simulacija sinkronog motora s površinskim magnetima (PM, SPM) i aksijalnim tokom za pogon električnog bicikla. Najprije su definirani zahtjevi motora (nazivna snaga i moment, maksimalna snaga i moment, maksimalna brzina, karakteristike namota, Halbach topologija, itd.). Nakon toga je napravljen analitički izračun motora i validacija dizajna motora pomoću 3D metode konačnih elemenata koja je koristila ručno nacrtani model napravljen u programu Fusion 360. Proveden je izračun 9 radnih točaka čiji podatci su obrađeni i korišteni za dobivanje mape korisnosti, karakteristika momenta, snage i gubitaka u stroju. Uspoređene su izračunate karakteristike i parametri motora na temelju podataka dobivenih analitičkim izračunom i onim provedenim u programima Simcenter Magnet i Matlab. Konačno prikazan je izrađen prototip i tehnička dokumentacija koja je korištena za izradu motora.

Abstract (english)

In this master's thesis paper, the calculation of a synchronous motor with surface magnets (PM, SPM) and axial flux for use in an electric bicycle was performed. First, the motor requirements were defined (rated power and torque, maximum power and torque, maximum speed, Halbach topology, etc.). After that we move on to the analytical calculation of the machine characteristics, which was performed in Matlab, and to the validation of the motor design using the 3D finite element method (Symcenter Magnet) which used a hand drawn 3D model made in "Fusion 360". A calculation of 9 operating points was performed, the data of which were processed and used to obtain an efficiency map, torque and power characteristics as well as the individual and total losses in the machine. The calculated characteristics and parameters of the motor obtained by the analytical calculation are compared to the analysis carried out in the 9 operating point simulations performed in the Simcenter Magnet program as well as Matlab. Finally, the prototype and the technical documentation used to make the motor were presented.
