Mode recognition and coordinated magnetisation control method for variable flux memory machine
Electronics Letters, Volume 57, Issue 15, Page 570-572, July 2021., 2021 Abstract The hybrid permanent magnet (PM) variable flux memory machine employs high‐ and low‐coercive‐force hybrid PMs to simultaneously obtain a high torque density and regulable PM flux property. The operating trajectories and steady working‐points of this type of machine switch back and forth in multiple regions.
