Patent
Motorized system integrated control and diagnostics using vibration, pressure, temperature, speed, and/or current analysis
Frederick M. Discenzo,Dukki Chung,Joseph K. Zevchek,Jan Bezdicek,Ondrej Flek,Bohumir Sladek,Petr Tusla,Jiri Ryba,Sarat Babu Vetcha,Peter J. Unsworth,Dragica Kostic Perovic,Srdjan Perovic,Muslum Arkan,Kenneth A. Loparo +13 more
TL;DR: In this paper, the authors present a system and methods for controlling, diagnosing and prognosing the health of a motorized system using a setpoint and a diagnostics signal from the diagnostics system and/or prognosis information.
Patent
Detection of pump cavitation/blockage and seal failure via current signature analysis
TL;DR: In this paper, a system and method for monitoring the operating condition of a pump by evaluating fault data encoded in the instantaneous current of the motor driving the pump is presented. But the authors do not specify the fault conditions associated with the pump.
Proceedings ArticleDOI
Induction motor fault detection by space vector angular fluctuation
TL;DR: In this article, a new method of obtaining diagnostic data from induction motors, derived from space vector angular fluctuation, is presented, which obtains data from stator current by exploring the position of the current space vector in the space vector plane.
Patent
System and method for motor fault detection based on space vector angular fluctuation
TL;DR: In this article, a diagnostics component adapted to obtain a space vector angular fluctuation from a current signal relating to operation of the motor, and to analyze the space vector fluctuation in order to detect at least one fault in the motor.
Proceedings ArticleDOI
Stator fault diagnosis in induction motors using power decomposition
Muslum Arkan,Peter J. Unsworth +1 more
TL;DR: In this paper, a power decomposition technique was used to derive positive and negative sequence components of arbitrary three phase signals in the time domain, in order to detect deterioration in the stator of induction motors.
