Dynamo system

A dynamo system comprises a flywheel mounted on a shaft intermediate its ends. A circular track means includes an inward groove structure to keep the ends of the shaft tracked inside while the flywheel rotating and spinning. The circular track means further includes a mechanism to allow a coupling means dangling around. The pair of coupling means for bearing the shaft ends and dangling the shaft ends inside the circular track means so that the shaft ends will move freely along the circular course of the circular track means while the flywheel rotating and spinning. The coupling means includes a bearing to carry a shaft's end. The coupling means further includes a mechanism to dangle the bearing around the course of the circular track means. A frame holds the circular track means. The cavity of the frame has sufficient space so that the flywheel can rotate and spin freely. A plurality of permanent or electro magnets are mounted in spaced relationship on the rim of the flywheel. And a plurality of armatures are mounted to the undersurfaces of the frame for producing induced electrical power when the magnets sweeping over. Therefore, the induced electrical power can be used by an external load. The dynamo system may be used as a motor to produce mechanical motion for an external drive.
