Flywheel power systems, also known as flywheel energy storage (FES) systems, are power storage devices that store kinetic energy in a rotating flywheel. The flywheel rotors are coupled with an integral motor-generator that is contained in the housing. The motor-generator is used to store and then harness energy from the rotating flywheel.
Flywheel energy storage systems are designed for regenerative braking applications, to supplement DC power in uninterruptible power systems (UPS), or for energy storage applications in power grids. Flywheel braking systems utilize a regenerative brake or other hybrid kinetic energy recovery system (KERS).
The design of the motor for flywheel energy storage mainly adopts the stator core, winding, magnet, and a matching optimization to improve the power and efficiency. The challenge in motor design is to reduce the loss of the permanent magnet motor rotor and prevent the failure of the motor caused by high-temperature rise. 3.3.
