Moreover, the force modeling of the magnetic levitation system, including the axial thrust-force permanent magnet bearing (PMB) and the active magnetic bearing (AMB), is conducted, and results indicate that the magnetic forces could stably levitate the flywheel (FW) rotor.
The magnetic levitation system, including an axial suspension unit and a radial suspension unit, is the core part of suspending the FW rotor to avoid friction at high rotating speed, and then the storage efficiency of the MS-FESS is further improved by reducing the maintenance loss.
To improve the rotational speed and reduce maintenance loss, magnetic levitation technology is utilized to actively regulate the displacements of the FW rotor in the FESS, considering the benefits of zero contact [23, 24] and active controllability [25, 26].
Moreover, the magnetic levitation system, including an axial thrust-force PMB, an axial AMB, and two radial AMB units, could levitate the FW rotor to avoid friction, so the maintenance loss and the vibration displacement of the FW rotor are both mitigated.
As a vital energy conversion equipment, the flywheel energy storage system (FESS) [, , , , ] could efficiently realize the mutual conversion between mechanical energy and electrical energy. It has the advantages of high conversion efficiency [6, 7], low negative environmental impact [8, 9], and high power density [10, 11].
Conclusion A compact flywheel energy storage system sustained by axial flux partially-self-bearing permanent magnet machine has been proposed and the prototype has been built up to validate the feasibility of the design concept. The PID control algorithm has been implemented in a DSP-based control platform.
