Experimental study on cogging-torque reduction of transverse-flux motor with skewed armature cores

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017
Transverse-flux motors are suitable for getting high torque density by increasing their number of poles owing to the independent coil design from the number of poles.

Impact of Flux-Modulated Rotor Design on Special Flux Density Harmonics in PS-DSPM for Cogging Torque Minimization

Journal of Applied Science and Engineering
High cogging torque caused by a fluctuating magnetic flux distribution in the partitioned stator doubly salient permanent magnet machines (PS-DSPM), due to their double air gap design, limits their application despite excellent torque density ...

Influence of the amount of permanent-magnet material in fractional-slot permanent-magnet synchronous machines [PDF]

, 2014
The efficiency of permanent-magnet (PM) synchronous machines with outer rotor and concentrated windings is investigated as a function of the mass of magnets used, keeping the power, volume, and mechanical air-gap thickness constant. In order to be useful
