Signal based condition monitoring techniques for fault detection and diagnosis of induction motors: A state-of-the-art review

, 2020
Uninterrupted and trouble-free operation of induction motors (IMs) is the compulsion of the modern industries. Firstly, the paper reviews the conventional time and spectrum signal analyses of two most effective type of signals, i.e. the vibration and the

Single- and Multi-Fault Diagnosis Using Machine Learning for Variable Frequency Drive-Fed Induction Motors

IEEE transactions on industry applications, 2020
In this article, an effective machine learning-based fault diagnosis method is developed for induction motors driven by variable frequency drives (VFDs). Two identical 0.25 HP induction motors under healthy, single-, and multifault conditions were tested

Incipient winding fault detection and diagnosis for squirrel-cage induction motors equipped on CRH trains.

ISA transactions, 2020
Stator/rotor winding faults are the common faults in squirrel-cage induction motor systems, which motivates the study of incipient fault detection and isolation (IFDI) to improve the safety and reliability of CRH (China Railway High-speed) trains.

Machine Learning-Based Fault Diagnosis for Single- and Multi-Faults in Induction Motors Using Measured Stator Currents and Vibration Signals

IEEE transactions on industry applications, 2019
In this paper, a practical machine learning-based fault diagnosis method is proposed for induction motors using experimental data. Various single- and multi-electrical and/or mechanical faults are applied to two identical induction motors in lab ...

FORCED OSCILLATIONS OF INDUCTION MOTOR

IFAC Proceedings Volumes, 1983
Abstract The general mathematical model of asynchronous machines is represented by means of a non linear either 5-th or 6-th order system of differential equations, according to the shaft elasticity is either taken into account or not. These models are sometimes linearized to study particular phaenomena, as for example forced oscillations due to ...

On induction motors control

IEEE Transactions on Control Systems Technology, 1997
This paper deals with the control of induction motors. First we show that field-oriented control can be simplified by considering the modulus square of the flux, namely F=f/sup 2/=/spl phi//sub a//sup 2/+/spl phi//sub b//sup 2/ instead of f. Second, we perform an input-output linearizing control without using any of Lie derivatives.

The Heating of Induction Motors

Transactions of the American Institute of Electrical Engineers, 1909
The object of this paper is to show the limitations imposed on the designer of induction motors by the heating of the machine, and also to show how this heating may be predetermined.

The induction motor

Electronics Education, 1993
This is the first of a series of articles intended to explain the principles behind the operation of a frequently encountered type of AC machine: the induction motor. The articles will briefly discuss the characteristics of various types of electric motor, indicating which features dictate the selection of a particular type for a given application ...
