Rotary energy storage mechanism

For "many many rotations", a pneumatic motor can act as both a compressor and motor. Spinning the motor causes air to be forced through a tube, one-way valve, and storage tank. Opening the valve allows the compressed air in the tank (potential energy) to flow back through the tube and motor, spinning it in reverse.

6 FAQs about [Rotary energy storage motor]

What size rotor is used in a flywheel energy storage system?

The shown unit features a rotor with a full-size 400 mm outer diameter but axial height scaled to 24% of the full-scale design with 1.0 kWh nominal capacity. Figure 1. Cutaway schematic of a flywheel energy storage system for experimental research. Inset shows the actual device [ 16 ].

Can a rotary motor store more energy?

For fast rotary motion this could work, but 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 7 ring flywheel energy storage system?
