Analisis Pengaruh Misalignment Terhadap Vibrasi Dan Kinerja Motor Induksi

Abstract

Vibration caused by misalignment of induction motor is detected by using Micro-Electro-Mechanical System (MEMS) and piezoelectric sensor. Measurement is done with alignment and misalignment. Vibration signal is presented by using LabVIEW trhough Data Aquisition (DAQ) Card and by monitoring variable of, voltage, current, electric power and motor speed. Vibration analysis is done by perceiving frequency and amplitude of signal with alignment and misalignment. Vibration analysis is done by using Fast Fourier Transform (FFT) and Wavelet Transform (WT). Calculation of energy consumption is done with alignment and misalignment. Keywords : misalignment, vibration, induction motor, MEMS, piezoelectric, LabVIEW, Fast Fourier Transform, Wavelet Transform
