6 FAQs about Solar Vertical flywheel energy storage

How does a vertical flywheel energy storage system affect power?

This will reduce motor power and affect the normal operation of the system. For vertical flywheel energy storage systems, most of the exergy loss in the heat transfer process is concentrated in the motor stator, casing, and cooling water. As the power increases, the proportion of exergy loss in the stator decreases.
