Zdalny system pomiarowy silnika indukcyjnego dla urządzeń przenośnych z systemem Android

The paper presents a concept of inexpensive remote measurement system for induction motor fault diagnosis, designed for the portable devices using Android OS. The hardware of system consist two current clamps for stator current measurement, two-channel data acquisition recorder and portable device (mobile phone or PDA) with specialized software. The diagnostic software takes advantage of motor current signature analysis method (MCSA) for detection of rotor and stator faults, voltage unbalance and mechanical load misalignment. All the measuring equipment are compact and battery-operated, that makes it usable in not easy accessible surroundings.
