MAGNETIC MOTOR Russian patent published in 2007 - IPC H02N11/00 H02K57/00 

FIELD: physics; using energy of permanent magnets to set rotor in motion.

SUBSTANCE: proposed magnetic motor has permanent magnets and ferromagnetic rotor in the form of ring or hollow ball accommodating first permanent magnet fixed therein. Second horseshoe permanent magnet is fixed outside the rotor. Magnetic fields set up by first and second permanent magnets are relatively orthogonal in rotor location area and act upon the latter with different magnetic forces. Time constant τ of rotor ferromagnetic material polarity reversal τ ≈ 0.09/ω_st, where ω_st is rated steady state angular velocity of rotor. Rotor revolves due to difference in forces acting upon this rotor while it is being saturated by mentioned permanent magnets which fits torques different in value and opposite in direction applied to mentioned rotor; their difference dictates resultant torque accelerating rotor to angular velocity limited by load torque (including friction of rotation) and magnetic viscosity of rotor ferromagnetic material at preset time constant of its polarity reversal process. Mentioned difference in forces acting on rotor is caused by difference in reluctance of respective magnetic circuits and difference in angles to rotor ring radius at which these forces are acting.

EFFECT: ability of setting rotor in motion in crossed magnetic fields of permanent magnets.
