Cogging Torque Reduction of a Flux-Intensifying Permanent Magnet-Assisted Synchronous Reluctance Machine with Surface-Inset Magnet Displacement

Energies
This paper investigates the impact of permanent magnet (PM) displacement and flux barrier extension on cogging torque in flux-intensifying permanent magnet-assisted synchronous reluctance machines (FI-PMa-SynRMs) with surface-inset PMs. Unlike prior work

Minimizing cogging torque in permanent magnet alternators

, 2020
Sürekli mıknatıslı üreteçler özellikle rüzgar türbinleri olmak üzere elektrik makinelerinde çok geniş bir alanda kullanılmaktadır. Ancak rotor yüzeyinde bulunan sürekli mıknatıslardan ötürü stator olukları ile etkileşimi sırasında vuruntu momenti oluşmaktadır. Bu sorun bu tip üreteçlerin fonksiyonelliğini olumsuz yönde etkileyen ana problemdir.

Analysis and Design of a Permanent-Magnet Outer-Rotor Synchronous Generator for a Direct-Drive Vertical-Axis Wind Turbine

Iranian Journal of Electrical and Electronic Engineering, 2014
In Permanent-Magnet Synchronous Generators (PMSGs) the reduction of cogging torque is one of the most important problems in their performance and evaluation. In this paper, at first, a direct-drive vertical-axis wind turbine is chosen.
