Abstract
A wind generator system includes a stationary frame, a shaft, mechanical bearings and a stator and a rotor, along with magnetic components configured to reduce or substantially eliminate various loads imposed on the mechanical bearings by the system and by wind. In particular, magnetic components at a bearing closest to the vanes of attached to the shaft act to impart a force on the shaft opposing gravity. Magnetic components at a bearing along the shaft distal from the vanes act to impart a force on the shaft opposing a bending force exerted by the shaft on the bearing at that point. Additional magnetic components act to oppose gravity adjacent the stator and rotor. Still further magnetic components act to impart a force on the shaft opposing the wind force.
