The invention provides an axial magnetic flux contra-rotating motor, a coaxial propulsion device based on the motor and an aircraft using the propulsion device, and optimizes the structure of the coaxial propulsion device based on the motor on the basis of retaining the advantages of the axial magnetic flux double-rotor motor. Compared with similar devices in the prior art, the coaxial propelling device based on the axial magnetic flux contra-rotating motor has the advantages of being simple in structure, light in weight, high in heat dissipation efficiency, convenient to maintain and the like. Specifically, on the basis of a motor of a YASA structure, connection between a first rotor and a second rotor of the motor is canceled, the magnetic pole direction of a permanent magnet in the second rotor is changed, the second rotor and the first rotor independently rotate oppositely, and two sets of paddles in opposite directions are driven to form the novel coaxial propelling device.
本发明提出一种轴向磁通对转电机以及基于所述电机的共轴推进装置和使用所述推进装置的飞行器,它在保留轴向磁通双转子电机优势的基础上优化了基于这种电机的共轴推进装置的结构,使基于轴向磁通对转电机的共轴推进装置比现有技术的同类装置具有了:结构简单、重量轻、散热效率高和便于维修等优点。具体地说,比如以YASA结构的电机为基础,取消其第一转子和第二转子之间的连接,并改变其第二转子中永磁体的磁极方向,使其与第一转子各自独立地对转,并带动方向相反的两组桨叶形成一种新型共轴推进装置。
