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.

The heat exchanger, gas to fluid, consists of a cylindrical wall separating fluid from gas and a helical strip forming secondary exchange surfaces which carry additional heat exchange members forming tertiary heat exchange surfaces to increase the active surface and the heat transfer coefficient in the gas compartment.

Heat exchanger with secondary and tertiary heat exchange surface

A fluid flow machine consisting of a stator, mounted underneath a hot water tank, and an armature-impeller unit arranged inside said hot water tank, being separated from said stator by a spherical, magnetically permeable separation wall, which generates a toroidal vortex inside the water tank. Said vortex conveys hot water from the upper region of the tank to its lower region until the whole tank is filled with water of a uniform temperature.
