چکیده
The mechanism of torque ripple generation by time and space harmonic magnetic fields in permanent magnet synchronous motors is investigated to obtain advanced motor designs. general expression between the ripples air-gap flux densities derived using Maxwell stress tensor. Both numerical experimental verifications this are carried out. By expression, difference surface interior discussed. Based on these investigations, shape rotor an optimized. It clarified that specific components thetorque can be reduced nearly zero optimizing shape.

Abstrakt Hlavními požadavky kladenými na pohybové osy NC obráběcích strojů jsou vysoká přesnost polohování a vysoká dynamika pohybů. Základní předpoklad pro dosažení těchto protichůdných předpokladů jsou tuhá a lehká konstrukce mechanické struktury stroje. Těmito parametry je dána výše první antirezonanční frekvence, která omezuje nastavení zesílení kaskádně uspořádaných regulátorů rychlosti a ...

Permanent Magnet Synchronous Motor (PMSM) variable-speed drive is widely used in the industry because of its particularly high mechanical power density, simplicity and cost effectiveness. Eliminating the mechanical sensor mounted on the shaft of the motors gives further improvement. These drives are referred to as “sensorless” electrical drives. In this paper a novel sensorless algorithm is pro...

A New Adaptive Self-Tuning Fourier Coefficients Algorithm for Periodic Torque Ripple Minimization in Permanent Magnet Synchronous Motors (PMSM) Torque ripple occurs in Permanent Magnet Synchronous Motors (PMSMs) due to the non-sinusoidal flux density distribution around the air-gap and variable magnetic reluctance of the air-gap due to the stator slots distribution. These torque ripples change ...
