The invention provides a magnetomotive force rapid conveying system.

In an embodiment of the present invention, referring to fig. 1, 2 and 6, the magnetomotive force rapid transport system 1 includes:

the track 10 is provided with a plurality of driving sections 101 and at least one inertia section 102, and any two driving sections 101 are connected through one inertia section 102;

the magnetic driving device 30 includes a first driving member 310 mounted on the driving section 101, and a second driving member 320 mounted on the bogie 210, wherein a magnetic force is generated between the first driving member 310 and the second driving member 320 to drive the traveling carriage 20 to move along the track 10.

Specifically, the magnetomotive force rapid transport system 1 mainly comprises a track 10, a traveling vehicle 20 and a magnetic driving device 30, wherein the traveling vehicle 20 comprises a bogie 210 and a carrying plate 220, the traveling vehicle 20 is arranged on the track 10 in a sliding mode through the bogie 210, the carrying plate 220 is arranged on the upper side of the bogie 210, and the carrying plate 220 can be used for carrying people and/or goods. For example, when the pallet 220 is used for cargo transportation, cargo may be carried directly on the pallet 220 or a container (e.g., a container) may be mounted on the pallet 220 to enhance the loading and unloading of the cargo.
