Stator iron loss of tubular permanent-magnet machines [PDF]
IEEE Transactions on Industry Applications, 2005 While methods of determining the iron loss in rotating permanent-magnet (PM) machines have been investigated extensively, the study of iron loss in linear machines is relatively poorly documented.

Comparison of stator-permanent-magnet brushless machines [PDF]
IEEE Transactions on Magnetics, 2008 This paper quantitatively compares two emerging stator-permanent-magnet (PM) machines, namely, the doubly salient PM and the PM hybrid brushless types. Both of them are attractive for electric vehicles and wind power generation.

COMPARISON OF MAGNETIC-GEARED PERMANENT-MAGNET MACHINES [PDF]
Progress In Electromagnetics Research, 2013 With the advent of magnetic gears, researchers have developed a new breed of permanent-magnet machines. These magnetic-geared permanent-magnet machines artfully incorporate the concept of magnetic gearing into the permanent-magnet machines, leading to achieve low-speed high-torque direct-drive operation.

Permanent Magnet Reduction by Current Harmonics Injection for Surface Permanent Magnet Machines [PDF]
2021 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD), 2021 This paper presents the analysis of multi-harmonic current injection in multi-three phase surface permanent magnet (SPM) machines. An analytical model, extended to a generic harmonic order, is used to describe and determine the no load flux density, the back electromotive force (BEMF) and the electromagnetic torque produced.
