Abstract

Traditional accelerometers suffer the issue of low signal to noise ratio (SNR) and the measured signals generally show more completed modulation due to the undesired installation. On-Rotor Sensing (ORS) technology has been proposed to solve this problem and achieve the low-cost and effective condition monitoring of rotating machines. This paper aims to develop more accurate and robust diagnosis of motor bearing faults based on the vibration of the ORS. Based on the general layouts of a motor driving system, the structural design and device integration of the ORS system are performed to make it be installed on the shaft end easier and achieve non-invasive measurement. Then the ORS outputs for the diagnosis of different types of bearing faults are deduced theoretically. Experiments of three different motors are carried out to validate the performance of the proposed ORS method. Compared to the On House Sensing (OHS) by the traditional accelerometer, the proposed ORS technology can provide more robust incipient motor bearing fault detection (e.g., inner race and outer race faults), with higher fault frequency amplitudes in the spectrum of low frequency bands.
