A shaftless magnetic trajectory fan principally includes a magnetic track, a controller and a magnetic fan. The magnetic track comprises two outwardly-opened U-shaped magnetic conducting rings coupled with each other, wherein each of the two U-shaped magnetic conducting rings has therein a ring-shaped magnet with different poles at the inner and outer edges, and the connection portion of the two U-shaped magnetic conducting rings has thereon another ring-shaped magnet with different poles at the inner and outer edges. The controller has thereon several electromagnets formed of coils. In addition, the magnetic fan includes a top cover with several blades on the outer edge and a magnetic-levitated main body, wherein the magnetic-levitated main body has therein a ring-shaped magnet, the magnetic-levitated main body is upwardly coupled with a ring-shaped magnet corresponding to the electromagnets of the controller, and the top cover covers the outer edge of the magnetic-levitated main body. The ring-shaped magnet provided in the magnetic-levitated main body is accommodated between the two ring-shaped magnets of the magnetic track, the ring-shaped magnet provided in the magnetic-levitated main body is suspended in the outer edge of the magnetic track according to the principle "like magnetic poles repel each other", and the ring-shaped magnet with which the magnetic-levitated main body is upwardly coupled drives rotation of the magnetic fan when a circuit flows through the electromagnets of the controller.
