Diametrically multipole magnetized magnet refers to the ring magnet has more than two alternating magnetic poles distributed over the entire inner diameter or outer diameter surface, thereby, diametrically multipole magnetized magnet is better known as multipole ring magnet. Diametrically multipole magnetized magnet is a more desirable solution to the permanent magnet (PM) motors and magnetic coupling devices in comparison with conventional splicing several diametrically magnetized arc magnets.
Diametrically multipole magnetized magnets are available in ferrite magnet and Neodymium magnet. Either radially orientation field or multipole orientation field should be applied during the molding process of anisotropic multipole magnets, then utilize specific magnetizing fixture to magnetize the required number of poles on the given working surface. Diametrically multipole magnetized magnets are generally select magnetic field strength waveform and magnetic flux as the comparative measurement of magnetic performance.
