The invention is a flywheel with apparatus that permits the flywheel's rotational inertia to be controlled during rotation. A flywheel attached to a drive shaft has at least two control masses attached such that they can move radially approximately orthogonal to the rotational axis in channels and slots in the flywheel structure. The control masses are mechanically attached to a shaft collar which rotates with and axially translates on the surface of the splined drive shaft. An electrical actuator controls the axial position of the shaft collar on the drive shaft and the resultant radial position of the control masses on the flywheel. The flywheel inertia is the sum of the inertias of the flywheel, shaft collar and the inertia of the control masses which is a function of their radial displacement relative to the rotational axis as controlled by the electrical actuator. Springs maintain forcible contact between the flywheel and variable inertia masses, and between the shaft collar and electrical actuator which keeps the composite mass center on the rotational axis.
