RPM to Frequency Formula:
| From: | To: |
The RPM to Frequency formula converts rotational speed in revolutions per minute (RPM) to frequency in Hertz (Hz). This conversion is essential in various mechanical and electrical engineering applications where rotational motion needs to be expressed as frequency.
The calculator uses the RPM to Frequency formula:
Where:
Explanation: Since 1 minute equals 60 seconds, dividing RPM by 60 converts revolutions per minute to revolutions per second (Hz).
Details: Frequency calculation from RPM is crucial in motor control, vibration analysis, rotating machinery design, and electrical systems where rotational speed needs to be synchronized with electrical frequency.
Tips: Enter RPM value in revolutions per minute. The value must be positive and greater than zero. The calculator will automatically compute the corresponding frequency in Hertz.
Q1: What is the relationship between RPM and frequency?
A: Frequency (Hz) equals RPM divided by 60, since frequency is measured in cycles per second and RPM is measured in revolutions per minute.
Q2: Why convert RPM to frequency?
A: Conversion is necessary when working with AC motors, generators, and systems where rotational speed needs to be expressed in standard frequency units for synchronization and control purposes.
Q3: What are typical RPM values for common applications?
A: Typical values range from 1,800 RPM for standard AC motors to 3,600 RPM for high-speed applications and down to 10-100 RPM for slow-moving machinery.
Q4: Can this formula be used for any rotating object?
A: Yes, this formula applies to any rotating object where you need to convert rotational speed in RPM to frequency in Hz.
Q5: How accurate is this conversion?
A: The conversion is mathematically exact and provides precise frequency values when accurate RPM measurements are available.
