摘　　要：在磁性齿轮的结构上,将磁性齿轮的内外双层永磁体都替代为交流绕组,中间为磁场调制铁块,形成双定子磁场调制电机(DSFM)。由于该电机励磁磁场和电枢磁场由定子三相绕组产生,无论励磁磁场还是电枢磁场都可以各自灵活地调节幅值、频率,而且励磁磁场和电枢磁场的功能可以灵活地互换。因此,该电机的转速和转矩调节范围可进一步提高。同时电机内部没有永磁体,因此不存在齿槽转矩问题。该文对该电机的结构以及控制理论进行研究,同时实现了该电机基于滑模观测器的无位置传感器控制。最后,利用仿真和样机试验验证了本文DSFM的运行原理和控制理论。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.
