FIELD : physics.SUBSTANCE : invention relates to physics and to direct conversion of radiation energy of radioactive isotopes and nuclear reactor wastes to mechanical rotational energy and can be used as a drive for various mechanisms. The magnetic-radiation motor has a radiation-protective stator with a permanent magnet, and a means of removing heat with a liquid coolant. A system for varying magnetic properties of the rotor is in form of two semicylinders on a common axis, one of which is transparent for radioactive radiation from a source situated at the centre of the semicylinders and the other is its shield. A ferromagnetic rotor made of radiation-sensitive material is in form of a fixed tubular coil, tightly mated with the inner surface of the stator and filled with a magnetic liquid coolant in form of a suspension of radiation-sensitive particles of rare-earth ferromagnetic materials and radiation-resistant liquid coolant, which directly communicates with a closed hydraulic drive which comprises a hydraulic accumulator, a heatsink and a blade turbine or a fluid motor, kinematically linked to a mechanical payload.EFFECT : high cooling efficiency and easy use, avoiding the need for dynamic balancing and performing heat transfer and loading beyond the radiation range.2 cl, 1 dwg
