- Abstract
- We herein propose a novel high-torque-density flux-switching permanent magnet machine
(FSPMM) which adopted phase-group concentrated-coil (PGCC) winding and a cogging torque
reduction technique. The PGCC winding was applied to increase the torque density. In order to
maximize the torque of the FSPMM that utilizes the PGCC windings, the performance according
to stator slots/rotor poles combinations were compared. A machine which had 12 stator slots and
13 rotor poles (12S13P) was selected for its top average torque value. However, the 12S13P PGCC
FSPMM contains high cogging torque that must be reduced. The cogging torque reduction technique
is applied, and the parameters used in the technique are further optimized to achieve the target
average torque, while suppressing the cogging torque as much as possible. The optimization process
was performed with a collaboration of the genetic algorithm and Kriging method. The analysis
results of the optimized design exhibited huge reductions in the cogging torque and eventually in the
torque ripple from the initial machine, with reasonable average torque reduction. The entire work
was evaluated experimentally using a manufactured prototype.
