Cogging torque and torque ripple reduction of modular permanent magnet machines
2016 XXII International Conference on Electrical Machines (ICEM), 2016In order to minimize the cogging torque and torque ripple for surface mounted permanent magnet (SPM) machines, this paper proposes a C-core modular stator which can be obtained by inserting flux gaps (FGs) into every stator tooth. The electromagnetic performances of C-core modular PM machines such as open-circuit flux linkage, phase back-EMF, cogging ...

Cogging torque reduction of a permanent magnet canned motor
2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA), 2016The method of adding auxiliary slots in the stator or rotor is presented to reduce the cogging torque of a permanent magnet (PM) canned motor. Based on the formula of cogging torque, the optimal number of auxiliary slots is derived. A 3D finite element (FE) method is used to analyze the effect of different shapes of auxiliary slots on the cogging ...

Cogging torque reduction with pole slot combination and notch
2014 International Conference on Electrical Engineering and Computer Science (ICEECS), 2014In this paper, we examine the basic method of reducing cogging torque by using the combination of slot and pole number with a simple software. The methods were applied to basic permanent machine designs and the performance was calculated using finite-element analysis (FEA).
