This paper proposes a kind of low iron-loss variable flux permanent magnet memory machine. The proposed memory machine can expand the speed range of machine, guarantee the operation efficiency of machine, avoid the irreversible demagnetization of PMs under high speed, and decrease the iron loss ofthe machine. Further, Taguchi method is used to optimize the proposed low iron-loss PM memory machine under magnetizing and demagnetizing current pulses respectively. Finally, the final optimum design scheme for the proposed low iron-loss variable flux permanent magnet memory machine is achieved by giving consideration to each optimization objective.
