Abstract

It is described a Nd-Fe-B permanent magnet (354) comprising 28-35 weight % of rare earth elements, wherein the content of the sum of Nd (Neodymium) and Pr (Praseodymium) is between 20 and 25 weight %, wherein the content of Ce (Cerium) is between 5 and 10 weight%, wherein the spatial extension, i.e. the height (h) of the magnet (354) in the main magnetization direction of the Nd-Fe-B permanent magnet (354) is between 18mm and 26mm. It is further described a rotor assembly (350) for an electromechanical transducer (340).
