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

Click For Summary

Discussion Overview

The discussion revolves around the types of friction encountered in energy storage flywheels, including aerodynamic and rotational friction, as well as the selection of motors and generators for these systems. The context is a school project focused on energy storage technologies, specifically flywheel systems.

Discussion Character

  • Homework-related
  • Exploratory

Main Points Raised

  • One participant is seeking resources on the types of frictions in energy storage flywheels and motor/generator selection.
  • Another participant inquires about the context of the question, suggesting a need for more information on the project.
  • A participant mentions that their research has yielded limited information, noting that magnetic bearings are a well-covered topic compared to others.
  • There is a suggestion to explore related threads on the forum for additional insights into practical considerations of flywheel energy storage.

Areas of Agreement / Disagreement

The discussion does not present a consensus, as participants are sharing inquiries and resources without resolving the specific questions raised about friction types and motor selection.

Contextual Notes

The discussion highlights a lack of depth in available resources on the specified topics, indicating potential limitations in existing literature or online content regarding flywheel energy storage.

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. :smile:
