After many years of research of sintrade NdFeB permanentmagnets it is now possible to create fully radially magnetized ringmagnets.
How this works is that during production many magnetic fields get put into one ring, in different directions. These radially neodymiumrings makes it possible to create sophisticated magnet solutions in a very specific way.
The most regular design of a magnet rotor, for example, is to put magnetsegments in every other magnetizing direction inside a steelring. With this new radially magnetized ring there is no need for that assembly with steelring + magnetsegments, which also can be a tricky solution. This new permanentmagnet is a type of a rotor by itself.
It important to notice that with every new dimension a new tool must be created (shape and magnetic coil for magnetization). This increases the startcost immensely for production. This method is for Companys that requires specific solutions and/or massproduction. Though if you are lucky there might already be a tool with your wanted dimensions, or a close to your wanted dimensions.
