How to release energy when the energy storage motor is halfway through

How does an energy storage system work?

Energy Storage: The system features a flywheel made from a carbon fiber composite, which is both durable and capable of storing a lot of energy. A motor-generator unit uses electrical power to spin the flywheel up to high speeds. As it spins, the flywheel accumulates kinetic energy, similar to how a spinning top holds energy.

How does a motor-generator work?

As the flywheel stores energy, it speeds up, and when it discharges, it slows down to release the stored energy. To make this happen, a motor-generator (MG) unit drives the rotating flywheel, converting electrical energy to mechanical energy, and vice versa. They’re connected in a way that controlling the MG also controls the flywheel’s operation.

What's a suitable energy storage method for slow rotary motion?

For slow motion, the pneumatic motor may leak and store little or no energy. For "many many many rotations", a permanent magnet motor /generator -> DC rectifier -> battery (or supercapacitor) may work to store considerably more energy.

What is a flywheel energy storage system?

Flywheel energy storage systems (FESS) are a great way to store and use energy. They work by spinning a wheel really fast to store energy, and then slowing it down to release that energy when needed. FESS are perfect for keeping the power grid steady, providing backup power and supporting renewable energy sources.

How does a spring store and release energy?

With a normal spring, you store energy by compressing it using a linear force, and it releases that energy by decompressing and exerting a linear force. The question is, is there a mechanical mechanism that stores energy by rotating force and releases it by rotating force?

Can a rotary motor store more energy?

For fast rotary motion, a rotary motor could work to store energy, but for slow motion, a pneumatic motor may 'leak' and store little or no energy. For 'many many many rotations', a permanent magnet motor/generator -> DC rectifier -> battery (or supercapacitor) may work to store considerably more energy than a linear motor.
