Abstract: The objects of research are three recently discovered white dwarfs from binary systems with rapid axial rotation and masses M ≤ M_☉. The geometrical and mechanical characteristics (moment of inertia, equatorial gravity, the condition of stability in relation to rotation) are calculated for the white dwarf V1460 Her within an electron-nuclear model, based on the equilibrium equation and inferred from observations mass and period of axial rotation. Estimates of model parameters and macroscopic characteristics for inferred from observations periods of rotation are performed for white dwarfs LAMOST J024048.51+195226.9 and CTCV J2056-3014.
