Problems solved by technology
[0002] Radially magnetized plastic magnets usually have two forms: internally charged multipole magnets and externally charged multipole magnets. Since the magnetic properties of radial magnetization change with the change of wall thickness, the magnetic properties of radial magnetization are Sine wave, if the wall thickness of the magnet is constant, it will inevitably cause waste of materials, which will greatly increase the cost of the product, and the increase in product weight will also increase the logistics cost

Embodiment Construction
[0011] A radially magnetized plastic magnet according to the present invention will be further described in detail through specific examples below.
[0012] like figure 1 As shown, a radially magnetized plastic magnet is in the form of a multi-pole magnet filled inside, and is an annular magnet 1. The outer wall of the magnet 1 is provided with outer grooves 2 evenly spaced along the circumference, and the magnet 1 The wall thickness changes with the regular size of the sine wave, and the position of the peak of the wall thickness is directly opposite to the position of the peak of the magnetic property.
[0013] like figure 2 As shown, a radially magnetized plastic magnet is in the form of an externally charged multi-pole magnet, and is an annular magnet 1. The inner wall of the magnet 1 is provided with inner grooves 3 evenly spaced along the ring direction, and the magnet 1 The wall thickness changes with the regular size of the sine wave, and the position of the peak of...

The invention relates to a radial magnetization plastic magnet. The radial magnetization plastic magnet is an annular magnet, the wall thickness of the magnet changes according to rules of sine waves, and the position of the wave crest of the wall thickness corresponds to the position of the wave crest of magnetic performance. According to the radial magnetization plastic magnet, the wall thickness of the magnet changes according to the rules of the sine waves and the position of the wave crest of the wall thickness corresponds to the position of the wave crest of the magnetic performance, so needed materials are greatly reduced, the product cost is saved, the product quality is improved, the logistics cost is lowered, and the product competitiveness is improved.
Description
technical field [0001] The invention relates to a radial magnetized plastic magnet. Background technique [0002] Radially magnetized plastic magnets usually have two forms: internally charged multipole magnets and externally charged multipole magnets. Since the magnetic properties of radial magnetization change with the change of wall thickness, the magnetic properties of radial magnetization are For sine waves, if the wall thickness of the magnet is constant, it will inevitably cause waste of materials, which will greatly increase the cost of the product, and the increase in product weight will also increase the logistics cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a radially magnetized plastic magnet that does not cause material waste. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: a radial magnetized plastic magnet, which is an annular mag...
