The problem is solved that a conventional electromagnetic coupling wireless power supply system of thefloating clearance structure has a coupling parameter varying in a large range, electromagnetic force disturbance and electromagnetic interference.

Description

technical field [0001] The invention belongs to the field of wireless power supply, and relates to a high-power wireless power supply system for a floating clearance structure. Background technique [0002] Floating structures are a class of key components in the fields of precision test and metrology, aerospace, inertial navigation / gyroscope, etc. Its principle is to isolate the contact between two sets of mechanical devices by means of suspension, thereby completely eliminating vibration and force transmission, and creating a local mechanically stable environment for precision components. Common floating structures include two-dimensional planar motion mechanisms such as pneumatic floating tables and electromagnetic floating tables, as well as magnetic bearings, two-axis, and three-axis rotating structures. [0003] Floating clearance refers to the air (or vacuum) gap between floating structures, usually ranging from a few millimeters to a few centimeters. The existence ...
