What is the difference between electrical and mechnical damping factor?

Click For Summary

Discussion Overview

The discussion centers on the differences between electrical and mechanical damping factors, exploring their definitions and implications in various systems, particularly in the context of a mini power generator. Participants seek to clarify the concept of electrical damping and its relation to mechanical damping, which is more familiar to some.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant asks for clarification on the meaning of electrical damping, contrasting it with mechanical damping, which they associate with friction and air resistance.
  • Another participant suggests that electrical and mechanical damping are analogous, with mechanical damping involving air resistance and electrical damping involving resistance in an LC circuit.
  • A further contribution introduces the concept of electromechanical damping, specifically mentioning motional damping and induced eddy currents in moving conductors within magnetic fields.
  • A participant expresses uncertainty about whether to neglect electrical damping in their mini power generator project, noting that some papers include it while others do not, leading to confusion regarding the equations needed for their system.
  • The same participant acknowledges gaining a better understanding of electrical damping's relation to eddy currents through the discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the treatment of electrical damping in the context of the mini power generator, with differing views on its significance and relevance in the equations being discussed.

Contextual Notes

There are limitations in the discussion regarding the definitions and implications of electrical damping, as well as the specific conditions under which it may be relevant or negligible in practical applications.

what is the difference between electrical and mechnical damping factor?
what i mean is that,
what is mean by electrical damping? the mechnical damping i know that is related to those frction, air resistance... how about electrical?

[PLAIN]http://a367.yahoofs.com/hkblog/UR9Z27ORHxrdwGytSmoxuE_Bgw--_1/blog/20110325062119959.jpg?ib_____D30UcZEqy

i have seen some paper had used those parameters,but i have no idea about that.
even i can't find in wiki..

can anyone help me!thxxxx so muchhh

They analogs of each other and are Resistance...

In the mechanical system you might have some air in that cylinder that "damps" the oscillation of the piston. In an electrical system you'd have a resistor that damps the oscillation of an LC circuit.
 
Thx you all to answer this question!reli thxxx

but, since i m doing a mini power generator. can i just neglect the electrical damping one? because i have seen some paper that some may contain this and some may not.
and i am not so familiar with this part of the knowledge..so i m so confuse to proof those equation in order to have a response function with the
displacement input and the induced voltage output system.

and so thankyou that i have more idea about the electrical damping part which is related to the eddy current. =]
reli thxxx!
