“…However, it was possible to nical specifications, which give a shown in Table IV. A thorough documentation of an FESS for a transit bus pursuing a different, more costly approach using magnetic bearings and a gimbal mount can be found in [6]. The basic vehicle -the Advanced Technology Transit Bus -was designed by Northrop Grumman while the FESS was contributed by the Center for Electromechanics of the University of Austin, Texas.…”

Even though the r&d activities in the field of energy storage are currently being pushed all over the globe, the results are still far from satisfactory. This paper describes how the benefits of flywheel energy storage systems (FESS) can be exploited even though some properties still need to be improved significantly in the near future.Within a research project at the Graz University of Technology an FESS for application in vehicles serving urban public transportation (UPT) was investigated. The systematic design process and the problems of the proposed topology are discussed. Finally, solutions are suggested, which allow the maximum exploitation of the properties of kinetic energy storage. These recommended solutions do not only affect the flywheel design itself, but also its mode of application. This means that a holistic approach was chosen, which takes into account the whole supersystem of the flywheel hybrid vehicle.Index Terms-Automotive engineering, energy storage, flywheel, hybrid vehicles, methods of development, research and development management.

A flywheel energy storage system using an active magnetic bearing (AMB) is an effective method for storing electric power and reducing energy consumption. The stabilization of a flywheel rotor system supported by magnetic bearings fixed on the ground has been done. Currently, an electrical vehicle with a flywheel energy storage system using a magnetic bearing and a two-degree-of freedom gimbal which means two-axis gimbal have been carrying out. In this paper, the mathematical model for both the flywheel and the gimbals has been derived. Also, a discussion of the gimbal design is presented. It was verified through experiments that the proposed model in this paper is very effective.

To reveal how the base motion influences the magnetic suspension dynamics in a vehicular FWB, this paper makes some simplification of the magnetic suspended vehicular FWB at this first research stage and fabricates a novel and concise magnetic suspended disk test device as a simplified FWB model, and sets up a vibrating-base magnetic suspend disk test system. A series of computer controlled sine and random vibration signal with different frequencies are applied to the base and the dynamic response of the suspended disk are measured through several accelerometers mounted on the disk. The test data of interaction between input base vibration signal and the disk dynamic response are analyzed for controller improvement.
