Title:
MULTI-SET MULTI-DISK MULTI-AIR-GAP LINKED ADJUSTMENT TYPE MAGNETIC COUPLER
Document Type and Number:
WIPO Patent Application WO/2023/207003
Kind Code:
A1
Abstract:
Disclosed in the present invention is a multi-set multi-disk multi-air-gap linked adjustment type magnetic coupler, comprising multiple movably connected composite disks, each composite disk comprising a conductor rotor set and a permanent magnet rotor set, wherein the permanent magnet rotor set comprises two permanent magnet yoke iron disks connected to each other and movable relative to each other in an axial direction, and permanent magnets respectively arranged on two permanent magnet yoke iron disk surfaces; and the conductor rotor set comprises two conductor yoke iron disks fixedly connected to each other, and conductors respectively arranged on two conductor yoke iron disk surfaces. In the present invention, the conductor rotor sets are used as driving ends, the permanent magnet rotor sets are used as driven ends, and vice versa; each composite disk forms two air gap lengths and forms multiple sets of air gap lengths with other composite disks; in addition, a single set of driven end rotors are driven by a speed adjustment device to realize axial relative displacement, and multiple air gap lengths of the multi-set multi-disk magnetic coupler are subjected to linked adjustment, so that the purpose of speed adjustment or torque change of the magnetic coupler is realized. By means of the structure, a large electromagnetic torque and a high power can be obtained, and thus the structure can be applied to occasions where there is a large axial size but a limited radial size, such as on ocean platforms and large vessels.
