FAQS about Core technology of magnetic levitation flywheel energy storage
What is a compact and highly efficient flywheel energy storage system?
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.
How does a flywheel energy storage system work?
A flywheel energy storage system (FESS) uses a high speed spinning mass (rotor) to store kinetic energy. The energy is input or output by a dual-direction motor/generator. To maintain it in a high efficiency, the flywheel works within a vacuum chamber.
What is a magnetic levitation system?
Modelling of magnetic levitation system 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.
Can magnetic forces stably levitate a flywheel rotor?
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.
What is a flywheel energy storage system (fess)?
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].
How can magnetic levitation improve the rotational speed and reduce 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].
