Embodiment Construction
[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0043] A near-field magnetic positioning method for a ring magnet proposed by the present invention, its overall realization block diagram is as follows Image 6 As shown, it includes the following steps:
[0044] ① Construct the magnet coordinate system OXYZ, then construct the integral model of the magnetic field distribution of the ring magnet in the magnet coordinate system OXYZ, and then use the integral model of the magnetic field distribution of the ring magnet to obtain the space point of the ring magnet on the plane YOZ (axial symmetry plane) The generated magnetic flux density vector, the specific process is:
[0045] ①_1. Taking the center point of the ring magnet as the origin, and taking the axial symmetry axis of the ring magnet as the Z axis, construct the magnet coordinate system OXYZ.
[0046] ①_2. Construct the integral mod...
