摘　　要：在电驱动对转推进领域,横向错位磁场调制型无刷双转子电机(transverse-dislocated magnetic-field-modulation brushless dual-rotor machine,TDMFM-BDRM)具有无旋转绕组且能够输出实时等大反向转矩的特点,解决了传统对转电机中旋转绕组可靠性差或双转子转矩协同控制难等问题。该文针对横向错位磁场调制型无刷双转子电机展开研究,基于三维磁场调制原理和绕组函数分析电磁转矩的影响因素及变化规律。揭示调制转子横向错位结构的导磁块斜极效应,分析永磁转子极对数、多单元结构和端部导磁块尺寸对定位力矩的影响,给出输出转矩不变下降低定位力矩和转矩波动的方法。进一步研究电机功率因数及其影响因素,给出结构参数和输入电流对功率因数的影响规律。最后,研制横向错位磁场调制型无刷双转子电机样机,通过实验对理论分析进行验证。In the field of electric drive contra-rotating propulsion,the transverse-dislocated magnetic-fieldmodulation brushless dual-rotor machine(TDMFM-BDRM)has the characteristics of no rotating winding and can output equal-opposite torques at any time,which solves the problems of poor reliability caused by the rotating winding or the difficulty in the coordinated control of dual-rotor torque in the conventional contra-rotating machines.In this paper,the research on the TDMFM-BDRM is carried out.Based on the three-dimensional magnetic-field-modulation principle and winding function,the influencing factors of electromagnetic torque and variation law are analyzed.The magnetic block skewing effect of the transverse-dislocated structure in the modulating rotor is revealed,and the influences of permanent-magnet rotor pole-pairs number,multi-unit structures,and the dimensions of magnetic blocks at the ends on cogging torque are studied.The method to reduce cogging torque and torque ripple under the constant output torque is given.The power factor of the machine and its influencing factors are further studied,and the influences of structural parameters and input current on the power factor are given.The prototype of TDMFM-BDRM is manufactured,and the theoretical analysis is verified by experiments.
