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

Minimizing the Influence of Cogging Torque on Vibration of PM Brushless Machines by Direct Torque Control

IEEE Transactions on Magnetics, 2006
This paper applies direct torque control (DTC) to a permanent magnet (PM) brushless machine, which maybe either brushless AC or DC, highlights the difference in its implementation when cogging is considered, and compares the performance which is achieved both with and without a consideration of the cogging torque. It is shown that DTC can automatically
