Abstract
The article presents a review of the literature on cryogenic electric machines. The advantages and disadvantages of their development and implementation, problems associated with the use of hightemperature superconductors are considered. Various approaches to cryogenic cooling of electric machines are considered, such as direct contact of the coolant with the active elements of the electric machine and cooling through the contact of the active elements of the electric machine with the refrigeration machine. A description of an experimental stand for assessing the prospects for the use of additive technologies in the design and production of windings for cryogenic electric machines and a test methodology for a printed winding made of aluminum alloy RS-300 (AlSi10Mg), manufactured by SLM printing are presented. The results of experimental studies are presented, during which the relationship between the winding temperature, current density and heat dissipation power is established. The characteristics of the printed aluminum winding are compared with a winding made of copper wire manufactured in a traditional way.
