Modeliranje in analiza asinhronskega sferičnega motorja

VIDRIH, MITJA (avtor), Miljavec, Damijan (mentor)

Sferični motorji bi lahko v prihodnosti, v veliki meri nadomestili današnje klasične enoosne, oziroma eno prostostne električne motorje. Zaradi svoje konstrukcije, sferični motorji izvajajo operacije v več prostostnih stopnjah. To pomeni, da bi bili pogoni opremljeni s sferičnimi motorji, lažji, manjši, bolj odzivni in cenejši. Zato se znanstveniki po vsem svetu trudijo razviti uporaben sferičen motor. V diplomski nalogi predstavim, modeliram in s pomočjo metode končnih elementov analiziram asinhronski sferični motor. Tridimenzionalni model asinhronskega sferičnega motorja sem zgradil v programskem okolju Flux. Mehansko je asinhronski sferični motor zgrajen dokaj enostavno, kar mi je olajšalo izdelavo njegovega računalniškega modela. Model motorja je narejen v tridimenzionalni tehniki s ciljem pridobiti čim bolj natančne rezultate. Rezultati simulacij so pokazali, da ima v primerjavi s klasičnim motorjem, sferični asinhronski motor slabše zmogljivosti. Ugotovil sem, kje so glavne pomanjkljivosti sferičnih motorjev in prišel do sklepa, da današnja stopnja razvoja motorjev z več prostostnimi stopnjami ne zadošča za njihovo množično uporabo.

Izvleček

In the future, spherical motors could largely replace traditional single-axle, single degree of freedom electrical motors. Due to their design, spherical motor can operate in several degrees of freedom. This means that the drives where spherical motors are used can be lighter, smaller, more responsive and more cost-effective. Consequently, scientists worldwide are trying to develop a useful spherical motor. The goal of this thesis is to present, to model and to analyze spherical induction motors by means of finite element method. Three dimensional finite element model of spherical induction motor was built up in Flux software environment. The mechanical construction of spherical induction motor is relatively simple, which significantly facilitates development of the 3D finite element model. The numerical modeling and analysis in three dimensional environment allowed me to obtain accurate results. The simulation results showed that spherical induction motor does not achieve the same or at least comparable performance as conventional single degree of freedom induction motor. I therefore determined the main disadvantages of the spherical machines and concluded, that at the time being the development of multi degree-of- freedom spherical motors has not yet achieved the level for their massive use and production.
