Drive
AssemblyDirect servo type spins the flywheel with a large torque motor coupled straight to the screw; friction type presses a spinning disc against the flywheel rim to spin it up before each blow. Either way the drive accelerates the flywheel, the blow spends its energy, and the drive reverses for the return. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
