Rotor Misalignment Detection using a Wireless Sensor and a Shaft Encoder

By Lufti Arebi, Fengshou Gu and Andrew Ball

Abstract

Mechanical systems such as motors, pumps, engines, and turbine are all operating based on different shafts. Due to unexpected operating conditions, various faults such as cross-sectional cracks, looseness and misalignment may occur during their service life. This paper presents the analysis of collected signals from a wireless sensor and a shaft encoder and compares their responses under different degrees of shaft misalignment. The results have shown that the wireless sensor outperforms the encoder in detecting small shaft misalignment
