FERRO-MAGNETO-VISCOUS ROTATOR Russian patent published in 2007 - IPC H02N11/00 H02K57/00 

FIELD: physics, possible use for producing rotary movement with usage of energy of magnetic field of constant magnets.

SUBSTANCE: ferro-magneto-viscous rotator consists of connected constant magnet having homogeneous or heterogeneous magnetic field between its poles and ferromagnetic disk (ring) with rotation axis. The latter is made of ferromagnetic material with magnetic viscosity, relaxation constant τ of which relatively to rotation period T of ferromagnetic disk (ring) is selected, for example, in accordance to condition: τ˜TX₀/4,4πR, where X₀ - length of magnetic space between poles of constant magnets, where the edge of ferromagnetic disk (ring) of radius R is positioned. Strength of magnetic field in the constant magnet space is selected to be saturating for the material of ferromagnetic disk (ring). Probability of rotation is ensured due to lagging of magnetic "gravity center" of ferromagnetic disk (ring) in dynamics of rotary movement thereof, which "gravity center" belongs to the part of ferromagnetic disk (ring) positioned in the field of constant magnet from center of attraction of constant magnet, creating force of attraction from the constant magnet side, applied to edge part of ferromagnetic disk (ring). Mechanism for drawing in ferromagnetic with heterogeneous magnetic field with magnetic sensitivity depending on saturating magnetic field, and mechanism for lagging of aforementioned value in dynamics of ferromagnetic disk (ring) rotation due to magnetic viscosity, are combined.

EFFECT: production of rotary movement of ferromagnetic disk (ring) in a field of constant magnet.
