Abstract
An inertia motor for a toy has a housing supporting a rotating flywheel. The flywheel has a disk with generally radially movable elements, movement of which vary the moment of inertia of the disk. Another element is supported by the housing so as to be movable towards and away from the disk and is located so as to be able to engage at least one of the movable elements when the flywheel has slowed sufficiently. Angular momentum and energy in the flywheel at engagement is transferred to the housing. The housing may also include a transmission such as a gear train to connect the flywheel with one of more elements of the toy to be powered by the flywheel.
