Optimal Design of IPM Motors With Different Cooling Systems and Winding Configurations [PDF]
, 2016 Performance improvement of permanent magnet (PM) motors through optimization techniques has been widely investigated in the literature. Oftentimes the practice of design optimization leads to derivation/interpretation of optimal scaling rules of PM ...

Active cogging torque construction by the weld slot design in a positioning servo system
IET Electric Power ApplicationsThe cogging torque is usually considered as an adverse effect of the PM machine servo system. This paper presents a new perspective that the cogging torque can be exploited in many practical situations as long as the speed ripple can be suppressed.

Suppression of Cogging Torque for Line-start Permanent Magnet Synchronous Motor
Journal of Harbin University of Science and TechnologyThe stator and rotor of line-start permanent magnet synchronous motor ( LSPMSM) are slotted on both sides, which greatly increases the difficulty of analyzing the characteristics of cogging torque of LSPMSM and studying its suppression methods.

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.

Cogging Torque Reduction in Permanent Magnet Brushless Motors
IEEJ Transactions on Industry Applications, 2002 This paper studies properties and reducing techniques of cogging torque in brushless motors with surface permanent magnets and winding slots. Desirable combination between stator slots and magnet poles, and relation between the slots and added notches are shown.

Actuators for a space manipulator [PDF]
The robotic manipulator can be decomposed into distinct subsytems. One particular area of interest of mechanical subsystems is electromechanical actuators (or drives). A drive is defined as a motor with an appropriate transmission.
