RPM and Frequency Basics
适用场景
Use this guide when teams mix rpm, Hz, and orders without writing down which shaft or gear stage they mean.
要使用的工具
Browser-based preliminary check for Rpm To Frequency Converter — fast estimates, not code or stamped design output.

- 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.
示例
- Pump at 1450 rpm mapped to Hz for vibration alarms.
- Four-pole motor approximate sync speed discussion.
应避免
- 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.

常见问题
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.
