I’m interested in building up an experimental setup for motor current signature analysis. Since I’m not from an electrical engineering background I do have some doubt regarding the equipment like sensors and DAQs. Many literatures are showing expensive equipment used for experimental setup. Will it be enough to use a DAQ (https://www.dataq.com/products/di-1110/) with up to 160 kHz maximum throughput sampling rate and 4-20-mA to get current waveform required to do motor signature analysis using discreet wavelet transform? Can you also suggest a cost effective current sensor?
