Generator i.e. diesel generator, for use in wind turbine, has permanent magnet rotating around two fixed coils, where one coil is attached to inner side of permanent magnet and another coil is attached outer side of permanent magnet

摘要

The generator has a movable hollow and cylindrical-shaped permanent magnet having two parts. The permanent magnet rotates around two fixed coils, where one of the coils is attached to inner side of the permanent magnet and another coil is attached outer side of the permanent magnet. Strength of the magnetic field is based on the shape and size of the permanent magnet.
