Solution Approach 1:

The patent changes the physical parameters of the magnetic field by introducing magnetic focusing materials (such as soft magnetic composites or ferrite materials) with specific permeability characteristics. These materials concentrate and direct the magnetic flux between the rotating and linear motion components, increasing the magnetic field strength in the interaction region. This parameter change in magnetic field density directly improves the coupling efficiency between rotary and linear motion, thereby enhancing energy conversion efficiency and reducing energy losses.

AI summary

A permanent magnet is rotated about an axis extending between opposing north and south poles. The magnetic field of the rotated permanent magnet interacts with magnetic fields of permanent magnets carried by a shuttle for repelling and attracting the fixed permanent magnets, and providing a linear reciprocating movement of the shuttle responsive to the rotary motion of the rotated permanent magnet.
