Main Performances and Features：

① Adopt multi-phase high-speed permanent magnet motor to reduce rotor loss.

② The bearing system adopts hybrid structure of electromagnetic bearing, permanent magnet unloading bearing and mechanical protection bearing, greatly improving operational stability

③ Combine 1.25MW single flywheel units into flywheel arrays, featuring fast response speed and larger energy storage capacity than single units.

④ Meet the primary frequency regulation demands of wind power, photovoltaic and thermal power, and support auxiliary AGC frequency regulation for thermal power units.

⑤ Adopt underground well-type installation, enabling flexible assembly of flywheel arrays according to application scenarios.
