A magnetic levitation hollow fan is suspended without contact and frictional wear. Rotor blades are connected into a whole through an inner hub and an outer hub, a wing tip part is guaranteed by the outer hub, a wing blade surface is wide and large in stress and does not deform, a wing root part has an enough space for arranging the wing root far away from a center of a circle, and due to the factthat the number of the rotor blades is large, the blade surface is wide and rotor compactness reaches more than 0.9, and a large-air-volume driving force can be generated through low-speed operation.A noise is low when a rotating speed is low and the noise is reduced A disc type linear motor is adopted as power drive, an acting point is far away from the center of a circle, and according to a lever principle, one tenth or less power can be used for generating a power effect equivalent to the power effect generated by a high-power engine needed by mechanical center shaft transmission. And a plurality of low-power linear motors are adopted for driving so that a starting current is small, and heat dissipation is facilitated. Direction-adjustable circular and fan-shaped air inlets and outlets and grid blades on end covers of an upper buffer air chamber and a lower buffer air chamber are matched with the air inlets and outlets and the grid blades at the front end and the rear end, a windstate mode of the airflow direction is changed through opening and closing conversion, and vertical take-off and landing, hovering and flying are achieved.

    磁悬浮空心风扇悬浮无接触,无磨擦磨损。旋翼叶片由内毂和外毂相连成一体,翼尖部有外毂作保障,翼叶面宽受力大不变形,翼根部远离圆中心有足够空间设置翼根,因旋翼叶片数多、叶面宽,旋翼实度达0.9以上,所以低速运转就能产生大风量的推动力。转速低噪音就小,降噪。采用圆盘式直线电机作动力驱动,着力点远离圆中心,据杠杆原理可用十分之一或更小的动力就能产生相当于机械中心轴传动所需的大功率发动机产生的动力效果。采用数台小功率直线电机驱动,启动用电流小,且利散热。通过上下缓冲气室端盖上的可调向圆形、扇形进排气口及栅叶片和前后端进排气口及栅叶片相配合,开闭转换改变气流方向的风态模式,实现垂直起降、悬停、飞行。
