MAGNETOVISCOUS ROTATOR Russian patent published in 2008 - IPC H02N11/00 H02K57/00 

FIELD: physics.

SUBSTANCE: invention may be used as a device for converting the magnetic field energy into mechanical rotary motion. The magnetoviscous rotator contains a permanent magnet with homogenous or inhomogenous magnetic field between its poles and a ferromagnetic disk (ring) with an axis of rotation, linked with each other. The ferromagnetic disk is made of ferromagnetic material with magnetic viscosity, the relaxation constant of which τ relative to the ferromagnetic disk (ring) rotation period T is selected, for example, according to the condition: τ˜TX₀/4.4πR where X₀ is the length of the magnetic gap between the permanent magnet poles. An edge of the ferromagnetic disk (ring) with the radius R is placed in the said magnetic gap. The magnetic field strength in the permanent magnet gap is selected as saturating for the ferromagnetic disk (ring) material.

EFFECT: power efficiency increase.
