It adopts high performance permanent magnet (neodymium iron boron) array, forms the fan-shaped magnetic block through axial magnetization, embeds in the hexagonal modularization magnetic yoke, and this design makes the magnetic field completely depend on the permanent magnet arrangement. At the same time, through the design of the pole head with pole head slanting of special size and the fan-shaped permanent magnet block placed below the pole head, the fan-shaped magnetic block with NS polarity up and down is formed through axial magnetization, so as to enhance the magnetic field uniformity and offset the edge leakage magnetic field.

But because the permanent magnet block itself has strong magnetism, when approaching the installation position, they will generate large force due to mutual attraction or repulsion. This makes the permanent magnet block difficult to accurately position, and the installation personnel often need to spend a lot of time and effort to adjust the position of the permanent magnet block, resulting in extremely low installation efficiency; secondly, due to the difficulty in accurately controlling the magnetic force between the permanent magnet blocks or between the permanent magnet blocks and other components, the permanent magnet blocks are prone to sudden jumping or deviation, and then violent impact with other components.
