ABSTRACT:
A rotor for an electric motor energized by permanent magnet means comprises positioning devices for permanent magnets. These positioning devices consist of positioning rings disposed in the region of each end face of a rotor body and at least one inner positioning ring disposed on the rotor body between the two. The positioning rings comprise positioning webs which extend only over a small part of the length of the outer peripheral surface of the rotor body and which partially define compartments for in each case a permanent magnet. On the one hand, this ensures accurate and simple mounting of the permanent magnet while at the same time it reduces the moment of inertia of the rotor.
