DOLOČANJE PODROČJA NAJVIŠJEGA IZKORISTKA SINHRONSKIH MOTORJEV S TRAJNIMI MAGNETI

Alić, Alen (author), Miljavec, Damijan (mentor)

V magistrski nalogi je predstavljen vpliv geometrije sinhronskega motorja s trajnimi magneti, ki ima topologijo trajnih magnetov v obliki črke V (IPM-V) na področje in lego maksimalnega izkoristka ter njeno prilagajanje glede na želeno obliko školjčnega diagrama izkoristka. V prvem delu je opisan matematični model sinhronskega motorja s trajnimi magneti. V drugem delu so predstavljeni modeli za izračun izgub v bakru, železu in trajnih magnetih. Poseben poudarek je na metodah, ki se uporabljajo za izračune izgub v železu, njihove prednosti in slabosti ter uporabnost. V tretjem in četrtem delu se posvetimo strategijam vodenja MTPA – maksimalen navor na Amper (angl. Maximum Torque Per Ampere), FW – slabljenje polja (angl. Field Weakening) in MTPV – maksimalen navor na Volt (angl. Maximum Torque Per Volt) za linearne in nelinearne modele motorjev s trajnimi magneti, kot tudi načinu vodenja v področju konstantnega navora in konstantne moči V nadaljevanju je na kratko opisana metoda končnih elementov ter principi računanja izgub v železu s pomočjo metode končnih elementov. V zadnjem delu magistrske naloge je predstavljen vpliv geometrije statorja in rotorja sinhronskega motorja s trajnimi magneti (IPM-V) na obliko školjčnega diagrama izkoristka.

• Title: DETERMINATION OF THE HIGHEST EFFICIENCY AREA OF PERMANENT MAGNET SYNCHRONOUS MOTORS

Abstract

The master's thesis presents the influence of the geometry of the permanent magnet synchronous motor, which has a topology of permanent magnets in the shape of the letter V (IPM-V) on the area and position of maximum efficiency and its adjustment according to the desired shape of the efficiency map. The first part describes the mathematical model of a synchronous motor with permanent magnets. The second part presents models for calculating losses in copper, iron and permanent magnets. Special emphasis is placed on the methods used for iron loss calculations, their advantages and disadvantages, and their applicability. The third and fourth part is focused on MTPA - Maximum Torque Per Ampere, FW - Field Weakening and MTPV - Maximum Torque Per Volt strategies for linear and non-linear models of permanent magnet motors, as well as control methods in the region of constant torque and constant power In the following, the finite element method and the principles of calculating losses in iron using the finite element method are briefly described. In the last part of the master's thesis, we presented the influence of the geometry of the stator and rotor of the permanent magnet synchronous motor (IPM-V) on the shape of the efficiency map.
