“…Finally, Fast Fourier transform (FFT) analysis, which has been very successful in recent years, has been performed on mechanical vibration signals. In this study, the FFT transform was preferred because it is the most widely used method in the literature in vibration analysis [18]. Fourier analysis is a tool used to reconstruct a periodic waveform using series harmonics, where the harmonic frequency is defined as a multiple of the fundamental and is used to convert a signal in the time domain to the frequency domain [19].…”

Internal combustion engines cause the engine to vibrate with a certain acceleration due to the oscillation of many components and combustion events during operation. The resulting vibrations can give information about the regular operation of the engine or a possible me-chanical failure. For this reason, it is very important to measure and interpret these vibrations in a healthy way. In this study, a microcontroller-based measurement system was designed and implemented to examine the vibrations of a 4-stroke, 3-cylinder and water-cooled diesel engine at different speeds, under loaded and unloaded conditions. Vibration results for three different measure-ment points at different engine speeds (900,1200,1600,2000,2400,2800 and 3200rpm) were recorded in the data recording system for 60s. The recorded data were filtered by the EMA method and the results were analyzed by the FFT method. According to the results obtained, it has been determined that there is a close linear rela-tionship between engine speed and vibrations. Results of measurement point 1 (Cylinder head) Higher vibration harmonics were measured compared to measurement points 2 (engine block) and 3 (Flywheel housing). The highest vibrations occurred at 3200rpm under loaded and unloaded operating conditions. As a result; It has been seen that the measurement sys-tem developed using MEMs-based accelerometers can be successfully applied to measure engine vibrations.

“…Predictive maintenance can be characterized as a set of efforts to compare, analyze and interpret engineering limits by measuring and examining trend data such as vibration, temperature, pressure, voltage, increases in the amperes drawn by the motors of the equipment in active operation, and to provide the most economical and fastest solution to the problems that may become malfunctioning [10,11].…”

Today, with the developing technology, it is important to establish facilities suitable for industry 4.0 in order to reduce CO2 emissions in factories, ensure efficiency, and automatically monitor the systems. Cement Factories are at the forefront of energy-intensive sectors. The cement industry is constantly focused on production, high energy demand and unforeseen failures lead to high-cost loss and systemic crises with the decrease in production/sales targets. Predictive maintenance, which is one of the maintenance methods, is aimed to solve the problems by determining the failure sources that may occur economically by examining and analyzing the physical parameters such as vibration, temperature, frequency changes, amperes, and spectra of the asynchronous motors in the field in trend data. In this study, dynamic and static analysis of large power asynchronous motors with a stator voltage of 6300V in cement plants are analyzed with the help of advanced measuring instruments. As a result of the analyses, a general evaluation study was carried out on the actions to be implemented in the maintenance plan by identifying the types of failures that may occur in advance.

In this study, the dynamic effect of stator turn-to-turn short-circuit fault on electrical, mechanical and magnetic motor parameters is investigated in detail. For this purpose, the Finite Element Method (FEM) based ANSYS@Maxwell-2D program is used, which enables steady state and transient analysis. The changes in stator current and induced back electromotive force voltage from electrical parameters, output torque from mechanical variables and leakage flux from magnetic parameters are examined in detail in both time and frequency axis by means of Fast Fourier Transform (FFT) for the faulty state. Moreover, in order to detect stator turn-to-turn fault, stray flux analysis is carried out and characteristics fault signatures are defined. The obtained results and findings have been proven through the developed experimental setup in laboratuvary.
