As shown in fig. 1 and 2, a driving device 300 for a magnetic levitation elevator according to an embodiment of the present invention includes a magnet mover 1 and a stator coil 2 engaged with the magnet mover 1; the magnet rotor 1 comprises a plurality of rows of magnet assemblies 100, the plurality of rows of magnet assemblies are arranged in parallel, and a coil gap is formed between each two rows of magnet assemblies and used for placing a coil; the stator coil 2 comprises a stator coil base 3 and a coil module 20 which is fixedly arranged on the stator coil base 3; the coil module comprises a plurality of coil assemblies 200, the coil assemblies are arranged in parallel, and a groove is formed between every two adjacent coil assemblies and used for accommodating the magnet assembly 100; due to the design, the N coil assemblies 200 only need N +1 rows of magnet assemblies 100, and compared with the independent design mode that each two rows of magnets correspond to one row of coils, the number of the magnets can be greatly reduced.

Referring to fig. 3 to 6, the magnet mover 1 includes a mounting base 10, and a magnet assembly 100 mounted on the mounting base 10; the mounting seat 10 comprises a base body 11 and a plurality of rows of magnet assembly mounting structures 12 arranged on the base body 11, wherein a plurality of groups of magnet assemblies 100 are mounted on each row of magnet assembly mounting structures; wherein, the interval d between two adjacent rows of magnet assembly mounting structures equals, and multirow magnet assembly mounting structures are parallel to each other, and the magnet assembly of the installation on two adjacent rows of magnet assembly mounting structures each other one-to-one to make magnet assembly 100 on the middle row of magnet assembly mounting structures receive the magnet attraction of the corresponding magnet assembly 100 of two adjacent rows equal. And a coil gap is arranged between every two adjacent rows of magnet assembly mounting structures and used for placing coils. By the design, N-1 rows of coils can be arranged between the N rows of magnet assembly mounting structures, and compared with the design mode that each two independent rows of magnets correspond to one row of coils, the number of the magnets can be greatly reduced. The embodiment of the present invention will be described by taking a mounting structure of five rows of magnet assemblies as an example.

Specifically, each row of the magnet assembly mounting structure comprises a plurality of magnet assembly fixing positions, and each magnet assembly fixing position is fixedly provided with one magnet assembly 100.

Specifically, in some embodiments, the first magnet block 101 and the second magnet block 102 have the same shape, and correspond to the rectangular frame 105 of the magnet assembly fixing position, and the first magnet block and the second magnet block are rectangular pieces. So design, the processing and the installation of the magnet piece of being convenient for do benefit to reduce cost. In some embodiments, the lengths of the first and second magnet blocks are greater than the height of the support column, so that the first and second magnet blocks can protrude out of the rectangular frame after being mounted at the rectangular frame, thereby facilitating the detachment of the magnet blocks. In practical application, if the length of the magnet block is too long, the protruding part is too much, and the magnet block is not stable easily after being installed on the rectangular frame; if the length of the magnet block is too short, the magnet block is inconvenient to disassemble, so that in the embodiment of the invention, the height of the support column and the lengths of the first magnet block and the second magnet block meet the following requirements:

wherein h is the height of the support column, and l is the length of the first and second magnet blocks. It should be noted that the length of the magnet block and the height of the supporting column may be set in other proportional relationships, and are not particularly limited in the embodiment of the present invention. In some embodiments, after the first and second magnet blocks are mounted in the rectangular frame positions, the surfaces of the magnet blocks protrude outward, so that the magnet blocksThe surface is displaced from the plane of the support post surface.
