RPM and Frequency Basics
該当する場合
Use this guide when teams mix rpm, Hz, and orders without writing down which shaft or gear stage they mean.

Browser-based preliminary check for Rpm To Frequency Converter — fast estimates, not code or stamped design output.
Rpm To Frequency Converter を開く →手順
- 1Identify which rotating element defines your fundamental mechanical frequency.
- 2Convert rpm to Hz with f = rpm / 60.
- 3Multiply by integer orders for blades, poles, or gear mesh tones when relevant.
- 4Compare against electrical line frequency only when you have a coupled motor scenario.
- 5Use FFT or tachometer data to validate assumptions on real equipment.
例
- Pump at 1450 rpm mapped to Hz for vibration alarms.
- Four-pole motor approximate sync speed discussion.
避けること
- Confusing mechanical rpm with electrical frequency without pole count.
- Using Hz for orders without stating the reference rpm.
- Ignoring slip in induction machines when precision matters.

よくある質問
Is this structural resonance?
No. It is kinematics only; resonance needs modal analysis.
Variable speed drives?
Operating point rpm follows the drive, not nameplate sync speed.
