ABSTRACT:
The invention relates to an electric drive having a stationary outer and inner stator and a rotor, a plurality of permanent magnet elements being disposed on the rotor for producing an excitation flux and at least one electrical field coil being provided. The rotor comprises at least one bell-shaped part having a cylindrical wall and a base wall. Said base wall is mounted perpendicularly and the cylindrical wall coaxially in relation to the axis of the rotor shaft. The base wall is connected to the rotor shaft for transmitting a force or a torque. The permanent magnet elements rest on one side on the cylindrical wall and are secured side by side to the rotor of the drive in the peripheral direction. The permanent magnets, interact with the outer and inner stator, to give magnetic circuits which completely extend through the cylindrical part of the rotor in the radial direction, the permanent magnet elements being arranged only on the exterior of the cylindrical wall.
