VPLIV DEBELINE ROTORJA NA KARAKTERISTIKE SINHRONSKIH STROJEV S TRAJNIMI MAGNETI IN AKSIALNIM MAGNETNIM PRETOKOM
Aleksander Strgar, 2011, master's thesis/paper

Abstract: V današnjem času se sinhronski stroji s trajnimi magneti in aksialnim magnetnim pretokom (SSTMAMP) čedalje več uporabljajo tudi kot generatorji vetrnih elektrarn. Zaradi razmeroma velikih mas tovrstnih generatorjev obstaja težnja po izvedbi čim lažjih generatorjev. V magistrskem delu je raziskan vpliv debeline rotorskih diskov na karakteristike SSTMAMP z dvojnim zunanjim rotorskim diskom. Izbran je bil obstoječi prototip SSTMAMP, v programskem paketu Ansys pa izdelan njegov tridimenzionalni numerični model, s pomočjo katerega je bilo možno, z uporabo metode končnih elementov (MKE), izračunati porazdelitev magnetnega polja kot osnovo za izračun karakteristik. Na podlagi izračunanih karakteristik SSTMAMP je bilo možno izbrati čim manjšo, vendar še ustrezno debelino rotorskih diskov SSTMAMP.

Design of fractional-slot permanent magnet synchronous motor with concentrated windings and interior permanent magnets
Bojan Štumberger, Miralem Hadžiselimović, Gorazd Hren, 2013, original scientific article

Abstract: The paper presents design of fractional-slot permanent magnet synchronous motors with concentrated windings and interior permanent magnets. Inner PM rotor machines with 12 slot/8 poles and 12 slot/10 poles were investigated. Finite element analysis is employed in order to determine the performance of each motor. It is shown that the maximal torque capability and the flux-weakening performance of the particular machine are strongly dependent on the stator slot number/rotor pole number combination, rotor barrier design and on the quality of used PM material.
