Design optimization for minimizing cogging torque in Axial Flux Permanent Magnet machines
2017 International Conference on Optimization of Electrical and Electronic Equipment (OPTIM) & 2017 Intl Aegean Conference on Electrical Machines and Power Electronics (ACEMP), 2017 This paper deals with the optimization of a single side Axial Flux Permanent Magnet machine (AFPMM) designs with respect to cogging torque. Although the AFPMMs run generally at high speed and high torque, these machines may run at lower operational speed for aircraft applications. At lower operational speed, the cogging torque is an undesirable effect.

Impact of the motor magnetic model on direct flux vector control of interior PM motors [PDF]
, 2011 The stator-field-oriented, direct-flux vector control has been proven to be effective in terms of linear torque control and model independent performance at limited voltage and current (i.e. in flux weakening) for AC drives of various types.
