Abstract
In a preferred embodiment, the flywheel electric transmission system is made up of three electric machines and a flywheel and is adapted for use in an automobile. The first electric machine is driven or energized by a prime mover such as a heat engine and is selectively clutched to the second machine. The flywheel and the armatures for both the first and second machines rotate as a unit. The third machine is connected to the second machine through gearing and, under the control of a computer, supplies excess electrical power to or consumes excess electrical power from the first and second machines that are functioning as either a motor or generator as required. In a second embodiment, the energy source is a battery pack.
