ROTOR FOR PERMANENT MAGNET GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a rotor for a permanent magnet generator capable of corresponding to a mounting position of a ring gear even when it is moved behind the bottom part of a flywheel. SOLUTION: This rotor is provided with a cup-shaped flywheel 2 mounting a permanent magnet 1 in the internal periphery and a ring gear 3b formed with an external diameter large than an external diameter of this flywheel 2 to rotate it. The ring gear 3b is arranged behind a bottom part 2c in an opposite side to a side of an opening part 2b of the cup-shaped flywheel 2 so as to conform the center of rotation to that of the flywheel 2. The ring gear 3b is supported to a ring gear holder 5 provided to protrude in divergent shape to the rearward from the external periphery of the bottom part 2c of the flywheel 2.
