FIELD: radial-flow turbines. SUBSTANCE: turbine has casing, wheel or wheels, magnets mounted on turbine wheel, and stator coils. Radial-flow turbine has no output shaft. Magnets are mounted on non-bladed side surface of turbine wheel. Side surface of turbine casing carries stator coils. Magnets are secured either on wheel surface, or in depressions that follow magnet shape, or in annular slot through magnet height, or under projection, or under shroud material effectively opposing inertia forces. EFFECT: reduced mass and size of turbine. 2 dwg
