MotorPitchAnalyzer (MPA) is a real-time app for measuring small motor speed.

Features & Capabilities

Motor Pitch Analyzer (MPA) is a real-time app designed to measure the rotation speed of small motors easily and accurately. By simply placing the motor near your smartphone's microphone, you can quickly obtain real-time RPM data. The app enhances measurement accuracy by allowing you to narrow the measurement range. It also displays the motor's maximum rotation speed, considering stable rotation and frequency intensity. Additionally, Motor Pitch Analyzer offers a quick way to assess motor shaft runout and brush conditions through real-time sound waveform visualization, providing rough guidance. For the best results, measurements should be made in a quiet environment. Keep in mind that accuracy may slightly vary based on your device's microphone performance.

User Reviews

I'm glad I found this! I was watching my laundry tumble in a front loading washer and thought, "I wonder if there's an app to find out the RPM of that drum." Turns out, I can get the approximate RPM of the motor from sound! That's awesome! As an electrician, I'll be sure to exhaust all the possibilities of usefulness this app has! Thanks to you! ...Crazy side note... it picked up my heartbeat and ticking wall clock in an otherwise silent room!
