Abstract: This article proposed a compact and highly efficient flywheel energy storage system. Single coreless stator and double rotor structures are used to eliminate the idling loss caused by the flux of permanent magnetic machines. A novel compact magnetic bearing is proposed to eliminate the friction loss during high-speed operation.
This can be achieved by high power-density storage, such as a high-speed Flywheel Energy Storage System (FESS). It is shown that a variable-mass flywheel can effectively utilise the FESS useable capacity in most transients close to optimal. Novel variable capacities FESS is proposed by introducing Dual-Inertia FESS (DIFESS) for EVs.
The proposed DIFESS has dual inertias, mounted on a common shaft of the motor/generator (M/G) set, as shown in Figure 1. The first inertia (Ifly1) is fixed on the shaft, while the second inertia (Ifly2) can either be engaged or rotate freewheeling using a clutch.
