Abstract
This paper proposes a Digital Signal Processor (DSP) based implementation of online air-gap torque estimator for detection of squirrel cage rotor faults. Two non-invasive, computationally efficient methods for online air-gap torque monitoring are discussed. In both the methods the air-gap torque is computed from two stator voltages and currents and is cost effective when compared with the use of a conventional torque transducer. The online air-gap torque monitor has been implemented using TMS320C31 and successfully tested on faulty cage rotors.
