Sintered radial neodymiuminfo-icon iron boron ring magnets are oriented by radial alignment of powders.  It can be straight, skew or unipole magnetized.  There are two production methods - sintered powder or hot press (MQ3) method.  Compared to traditional arc magnets or IPM (internal permanent magnetinfo-icon) assemblies, radial rings can improve motor performance and increase yields over traditional motor assembly methods.  These magnets are widely used in DC brushless and servo motors for robotic and automotive applications.
