Low frequency torque oscillations in the load can induce frequency components in the vicinity of that of rotor faults resulting in false alarms when applying motor current signature analysis (MCSA). False rotor fault indications due to load oscillations are most common in applications that employ speed reduction couplings for high torque, low speed operation. Recently, ideas for separating rotor faults and load oscillations have been proposed in the literature; however, the case where two… CONTINUE READING
