Induction Motor’s Health Diagnosis Based on Vibration Analysis Using One Chip Transducer: Feasibility of using MEMS accelerometers for motor health diagnosis

Abstract

This work is intended to check feasibility for the use of micro electro mechanical accelerometers for the purpose of electric motor’s vibration signature analysis. Here Lab-VIEW software is used for analysis and user interface. Vibration signal of motor is observed for various speeds and speed is changed by SPWM technique. The complete assembly of MEMS (Micro Electro Mechanical Systems) accelerometer ADXL 203 and interfacing devices (PCI 6221 and BNC 2120) is also verified with standard vibration signal generating laboratory equipment’s.
