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?

Based on the aforementioned research, this paper proposes a novel electric suspension flywheel energy storage system equipped with zero flux coils and permanent magnets. The newly developed flywheel energy storage system operates at high speeds with self-stability without requiring active control.

Can axial-type same pole motor be used as a flywheel energy storage system?

Ekaterina Kurbatova proposed a magnetic system for an axial-type same pole motor suitable as both motor/generator in combination with the integrated design of the motor/generator, which can be utilized in conjunction with the flywheel energy storage system.

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].

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.

Can a compact magnetic bearing eliminate friction loss during high-speed operation?

A novel compact magnetic bearing is proposed to eliminate the friction loss during high-speed operation. First, the structure and working principle of the flywheel energy storage system are described in detail. Then, the topology of the magnetic bearing is introduced, and its magnetic circuit model is built and analyzed.
