In rotating machinery one of the critical components that is prone to premature failure is the rolling bearing. Consequently, early warning of an imminent bearing failure is much critical to the safety and reliability of any high speed rotating machines. This study is concerned with the application of Recurrence Quantification Analysis (RQA) in fault detection of rolling element bearings in rot...

Increased running speeds and the requirement for rotating machinery to operate within specified levels of vibration mean that the control of machinery vibration is essential in today’s industry. In this work, the flexible rotor balancing problem based on the influence coefficient method and holospectrum technique is formulated as a minimax optimization problem. This formulation can solve the mi...

Electrical machinery plays a very important in industry and everyday life hari. Exsitasi or starting means used by man to ignite drive the electrical machinery. The way exsitasi machines taken get good efficiency power torque efficiency. Thus it takes piece of equipment that is capable performing with small big torque. Inverter more commonly known as VSD (Variable Speed Drive) one option which ...

This study investigated the status of mechanized power and self-propelled rice cultivation machinery in Guilan Province in northern Iran. The raw data was obtained from 2013 statistics of the Agricultural Jihad Organization of Guilan province. Power per unit of area, mechanization level, area per unit of self-propelled machinery, and mechanization requirement were calculated for eastern, wester...

Abstract Condition monitoring arises as a valuable industrial process in order to assess the health of rotating machinery, providing early and accurate warning potential failures allowing for planning effective realization preventative maintenance actions. Nowadays, machinery (gas turbines, wind etc.) manufacturers adopt new business models, not only equipment itself but also additionally takin...

Monitoring the vibration behaviour of large rotating machinery is an effective way to reduce production losses and enhance safety, efficiency, reliability, availability and longevity in manufacturing processes. As large rotating machinery is increasingly employed in continuous operations at high speeds and with heavy loads, the vibration behaviour of the rotor systems is more and more complex. ...

The development of electrostatic rotating machines for macroscale power conversion has been largely sidestepped, given the uncertainty its capabilities and place in technological hierarchy. This article reviews prior present works machinery identifies relevant machine types, their limitations, strategies performance improvement. separately excited synchronous presents greatest opportunity compe...
