A rotary device comprises a frame with a guide for flowing medium, a rotor with a number of blades, whereby a relation is obtained between the flowing medium and the rotation of the rotor, and energy converting means, the one part of which is connected to the frame and the other part to the rotor. The device has the feature that the end zones of the blades are connected to a ring, the ring has a radial section with the shape of an isosceles triangle or trapezium, the medium guide has an encircling recess, the form of which corresponds to the form of the ring and the ring fits with clearance into the recess, permanent magnets are added to the truncated conical surfaces, electromagnets debouch on both the corresponding surfaces of the recess, this such that the ring and the frame together form an annular induction motor or an electric generator.
Rotary Device, for Instance an Air Mover Such as a Fan, a Propeller or a Lifting Rotor, a Water Turbine or a Wind Turbine
