Abstract
An external rotor of a device for contactless transmission of rotary movements, for example of an electric motor, a magnetic transmission, a generator or a magnetic coupling, may include a plurality of different permanent magnet segments configured ring segment-like that are alternatingly arranged in a closed permanent magnet segment ring. At least one lateral surface of at least one permanent magnet segment of the plurality of permanent magnet segments may deviate from a radial direction. The at least one permanent magnet segment via the at least one lateral surface may be in contact with another permanent magnet segment of the plurality of permanent magnet segments.
