This paper describes a novel concept and configuration of Electric Vehicle powered by flywheel with Active Magnetic Bearing suspended by gimbal mechanism to the vehicle body. The entire system consists of AMB Flywheel Energy Storage including energy charger/discharger module, mechanical 2-DOF gimbal, steer-by-wire module, and autonomous driving module as the supervising controller. This paper shows the results of outdoor field experiments such as the feasibility test of steer-by-wire system, the implementation of input shaping to reduce vibration and gyroscopic effects, simple adaptive control method for flywheel attitude control, and the efficiency measurement of the energy conversion system.

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.
