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.

This paper deals an electric vehicle with fiywheel energy storage system using active magnet 量 c bearings ( AMBs ) and gimbaL At first the equation ofmotion of a flywheel energy storage system using active magnetic bearings and gimbal ． This equation of motion is a strong nonlinear equation ． So ， the approximated linear equation of motion is derived and the usefUlness of this approximated equation is made sure by experiments and simulation ． The spring constant of gimbal mechanism influences the natural 丘equencies ． The best design ofgimbal should be extreme low natural f セ equency ofgimbal ． Finally ， the ideal glmbal design method is proposed ，
