Abstract
By incorporating the concept of partitioned-stator into the flux-switching memory motor, a new stator-partitioned flux memory motor with AlNiCo and NdFeB permanent magnets (PMs) is proposed in this paper. Due to the partitioned-stator structure, the space competition among the armature winding, magnetization winding, and the two types of PMs is avoided effectively. Thus, the resulting new memory motor cannot only retain efficient online flux control, but also offer high power/torque density. An improved finite-element method coupled with a piecewise-linear hysteresis model of the AiNiCo-PM is performed to investigate the electromagnetic performance of the proposed motor. Both the static and transient simulation results verify the validity of the proposed motor.
