Cogging Torque Reduction by Elementary-Cogging-Unit Shift for Permanent Magnet Machines

IEEE Transactions on Magnetics, 2017
This paper describes a method to reduce cogging torque in permanent magnet (PM) machines by shifting elementary-cogging unit (ECU). The ECU division principle and the feature of cogging torque produced by ECU are also discussed. The proper shift angles for each ECU are deduced according to both fractional and integral slot number per pole, by which any
