What Types of Friction and Motors Are Best for Flywheel Energy Storage?

[Sara Samuel]

Energy Storage in Flywheels:

I am searching for resources on couple of topics 1) Types of frictions in energy storage flywheels -aerodynamic, rotational ... etc. and 2) Motor/Generator selection for energy storage flywheels.
Any links or references will be appreciated.

What have you found so far? Is this for a schoolwork project? What is the context of your question?

It's a schoolwork project of a Storage Device Systems class. I have to prepare a paper and a 15 min presentation on one of these energy storage topics. My search yielded few sites that touch on the subject without going deep into details. Maybe the only abundant topic is the magnetic bearings versus other kinds.

Check out the Related Links at the bottom of this page for more PF threads on flywheels. There was one in particular that was pretty long, and addressed a number of practical considerations of flywheel energy storage. Maybe try a PF forum search to help you find that thread.
