MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202431073896 A) filed by Indian Institute Of Technology Kharagpur; and Gail (INDIA) Limited, Kharagpur, West Bengal, on Dec. 30, 2024, for 'edge device for induction motor fault diagnosis.'
Inventor(s) include Ronit Dutta; Haraprasad Badajena; Bivash Chakraborty; Aurobinda Routray; Mamata Jenamani; Sanjeev Kumar; Lalit Kumar Maurya; and T. P. Yuvaraj.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "An edge device for induction motor fault diagnosis is disclosed. The edge device comprises a sensor configured to obtain a current signal from an induction motor and convert the current signal to a voltage signal using a transducer with galvanic isolation. A signal conditioning circuit is coupled to the sensor and configured to process the voltage signal to produce a clamped signal with reduced common mode noise. An automatic gain adjuster is coupled to the signal conditioning circuit and configured to dynamically adjust amplification of the signal. A processor is configured to convert the amplified signal to a digital format using an analog to digital converter. The processor conditions the digital signal to suppress noise using a noise rejecter and a low-pass filter. The processor detects fault frequency components and diagnoses motor faults by performance of spectral analysis and comparison of spectral peak amplitudes with threshold values."
