Motor and aircraft

The motor includes a rotor, a stator, and a flow pipe. The rotor is rotatable about a central axis extending in the axial direction. The stator has an annular stator core surrounding a central axis. And fluid can circulate in the circulation pipe. The stator further includes a plurality of coil portions disposed on the stator core. The runner pipe is provided with a plurality of connecting pipes which extend in the axial direction and are arranged in the circumferential direction. The connection pipes are disposed radially inward of the coil parts, and are in direct or indirect contact with the stator core. 马达具备转子、定子以及流通管。转子能够以沿轴向延伸的中心轴为中心旋转。定子具有围绕中心轴的环状的定子铁芯。流体能够在流通管中流通。定子还具有配置于定子铁芯的多个线圈部。流通管具有沿轴向延伸且沿周向排列的多个连接管。连接管分别配置于比线圈部靠径向内方，且与定子铁芯直接或间接地相接。
