Accurate motor RPM measurement
RPM measurement: Measuring motor speed isn’t always direct, especially when the shaft is hidden or contact sensors aren’t an option. Using FFT-based rotational speed analysis, motor RPM can be extracted directly from sound or vibration signals. That means:
🔹Non-contact measurement
🔹No reflective marks or mechanical modifications
🔹Works during acceleration and speed fluctuation
🔹Ideal for embedded or enclosed motors
