Recently, magnetic planetary and differential gearing has been developed for wind power generators. This report describes magnetic planetary and differential gearing having two sun gears, a configuration referred to as twin sun gears. This magnetic gearing decreased the thrust force and increased the transmitted torque with a magnetic closed circuit between the sun and planet gears. However, this gearing slipped down at low transmitted torque when four planets were used in the magnetic planetary gear. This was due to a meshing zone between the sun and planet gears or the sun and outer ring gears. The main contact zone is narrow and not an excited effective force. As a result, by only moving the phase shift angle of two of the four planets by 5°, the transmitted torque 18 increased by more than 50%.
