The possibilities of using metal glasses for magnetic cores of high-speed miniturbogenerators with a rotation frequency of up to 100000 rpm are studied. The existing amorphous and nanocrystalline alloys satisfying the requirements for designing miniturbogenerators are anlayzed. A numerical experiment is performed, demonstrating that the use of the domestic amorphous GM-440V alloy provides the possibility to halve the weight of the generator and increase its efficiency by 2%. Domestic nanocrystalline alloys are not inferior to foreign alloys in terms of their characteristics; however, they do not have sufficiently high values of the saturation magnetic flux density for use in magnetic cores.
