20.500.12556/DKUM-11890 ANALIZA VPLIVOV OBLIKE MAGNETOV NA SAMODRŽNI MOMENT MOTORJA S TRAJNIMI MAGNETI ANALYSIS OF INFLUENCES OF MAGNET SHAPE ON COGGING TORQUE OF PERMANENT MAGNET MOTOR V diplomskem delu je obravnavan motor s trajnimi magneti, ki se zaradi številnih dobrih lastnosti vse pogosteje uporablja v novejših električnih pogonih. Delo prikazuje projektiranje motorja s trajnimi magneti, ter konstrukcijsko zniževanje samodržnega vrtilnega momenta, ki je pri tem tipu motorja vedno prisoten. Izračuni vrtilnega momenta ter analize magnetnih razmer na osnovi 3D modela motorja so narejene s pomočjo programskega paketa Vector Fields — Opera, kateri deluje na osnovi metode končnih elementov. Za primerjavo so narejene magnetne analize treh različnih oblik polov trajnih magnetov. The diploma thesis considers a permanent magnet motor, which is for its good characteristics more and more often used in the newer electric drives. The thesis shows the design of permanent magnet motors and the design reduction of cogging torque, which is always present in this type of motor. Calculations of torque and of analyses of magnetic conditions based on the 3D model of the motor are made using the software package Vector Fields - Opera, which operates on the basis of the finite element method. For purposes of comparison, magnetic analyses of three different types of permanent magnet poles are made.
