Discussion Overview

The discussion revolves around the relationship between AC RPM and reactance, particularly focusing on how different components like capacitors and inductors behave with respect to frequency. Participants seek clarification on the context of the question posed, which appears to involve concepts related to electrical engineering and possibly applications in motors or welding.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants assert that reluctance does not change frequency, prompting a request for clarification on the context of the question.
  • One participant mentions the formula for capacitive reactance (Xc) being inversely proportional to frequency, while noting that inductive reactance behaves differently, being directly proportional to frequency.
  • There is a call for clarification on whether the discussion pertains to the RPM of an induction motor, the cutting speed of an arc welder, or the meaning of "rate of cutting in AC."

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are multiple interpretations of the original question and differing views on the relationship between reluctance and frequency.

TL;DR
For Rate of cutting in ac that means a higher frequency which also means a lower reactance theoretically. If so, why is higher rpm ideal?

No, you can't say that reluctance changes frequency.

Back up. Explain the context of your question please.

Ohh I was thinking about capacitors since Xc=1/(2*pi*f*c) where xc is inversely proportional to Frequency but in inductors they are directly proportional..

We still need context. Are you asking about the RPM of an induction motor? or the cutting speed of an arc welder? Or what does "rate of cutting in AC" mean?
