简介 The invention mainly relates to a claw-pole rotor (2) for a rotating electric machine, characterized in that said rotor comprises a plurality of magnets (20) that are located between the poles and are made of neodymium-iron-boron having a dysprosium content of less than 2% by weight. By keeping the dysprosium content in the magnets of the rotating electric machine to a minimum, the invention thus does away with the problems associated with the limited dysprosium supplies and its cost.
