Abstract：This paper presents a dual stator flux-modulation electric motor (DSFM), which is based on the structure of magnetic gear by replacing the inner layer and outer layer of permanent magnets (PMs) with stator AC windings, and the middle layer is iron segments for flux-modulation. As the excitation magnetic field and armature magnetic field are both generated by the stator AC windings in DSFM, the amplitude, frequency and angle of the excitation magnetic field and armature magnetic field can be adjusted flexibly. Moreover, the functions of excitation magnetic field and armature magnetic field can be exchanged with each other. Therefore, the regulation range of the speed and torque in DSFM can be further improved. Additionally, as there is no PMs in the motor, DSFM has no problem of cogging torque. The structure and operation principle of DSFM are studied in this paper. Furthermore, sensorless control method based on sliding mode observer (SMO) for DSFM is realized in the paper. Finally, simulation and prototype tests are carried on to verify the operation principle and control theory of DSFM.
