• wherein:
• the spindle is mounted in the turbine shell of the wind turbine through the front cross bearing bracket and the rear cross bearing bracket;
• the first spindle rolling bearing is arranged between the spindle and the front cross bearing bracket, and the second spindle rolling bearing is arranged between the spindle and the rear cross bearing bracket;
• the inner rotor vortex blade is fixedly mounted on the spindle;
• the inner rotor rotating body is fixedly mounted on the inner rotor vortex blade;
• the permanent magnet is fixedly mounted on the inner rotor rotating body;
• the outer rotor armature coil is positioned outside the permanent magnet and is fixedly mounted inside the outer rotor rotating body;
• a gap is provided between the outer rotor armature coil and the permanent magnet;
• the outer rotor vortex blade and the conductive slip ring are fixedly mounted outside the outer rotor rotating body;
• the first radial magnetic levitation bearing, the second radial magnetic levitation bearing, the third radial magnetic levitation bearing, and the fourth radial magnetic levitation bearing are respectively installed at an inner wall of the turbine shell via the first cross bracket, the second cross bracket, the third cross bracket and the fourth cross bracket;
• the first axial magnetic levitation bearing and the second axial magnetic levitation bearing are fixedly installed at the rear cross bearing bracket;
• the carbon brush set is located outside the conductive slip ring and fixedly mounted on the inner wall of the turbine shell;
• and
• the outer rotor rotating body rotates inside the turbine shell through the first radial magnetic levitation bearing, the second radial magnetic levitation bearing, the third radial magnetic levitation bearing, the fourth radial magnetic levitation bearing, the first axial magnetic levitation bearing and the second axial magnetic levitation bearing;
