6 FAQs about [Electromagnetic catapult 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.

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.

How does a flywheel work?

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. Active magnetic bearings (AMB) utilize magnetic force to support rotor's rotating shaft without mechanical friction. It also makes the rotor more dynamically controllable.

What were the advantages of EMALS catapults?

The EMALS catapults were able to launch aircraft more quickly and efficiently than the old steam-powered system, and the stresses on the aircraft were greatly reduced. The sailors who operated the system also found it to be much easier to use than the old system, requiring less manpower and fewer maintenance requirements.

How does a fess flywheel work?

To maintain it in a high efficiency, the flywheel works within a vacuum chamber. Active magnetic bearings (AMB) utilize magnetic force to support rotor's rotating shaft without mechanical friction. It also makes the rotor more dynamically controllable. A prototype of FESS with AMBs was developed.
