Abstract
A rotor of an electric motor with a spherical magnetic gap or an impeller which forms a pivotably mounted rotating unit with an armature consists of a permanent magnetic annular member which is arranged juxtaposedly to a second stationary permanent magnetic annular member. The two magnets are spaced apart from each other by an air-gap and remain apart from each other because of their polarity. This prevents tumbling and counteracts the hydraulic thrust to prevent liftoff of the rotating unit from the step bearing.
