Abstract:

The measurement of instantaneous torque in terms of voltage displaying rotating speed in revolution per minute (RPM) of a rotating shaft is known as a digital tachometer. An infrared module is used as the input that senses the interruption in terms of beam of rays caused by rotating shaft, generating a pulse. The usual method of counting pulse coming from the encoder in a fixed period of time produces a high precision velocity estimate in the high-speed range. The encoded signal is latched and further sent to decoder that decodes the latched pulse i.e. speed displayed in 7 segment display. Thi

Abstract:

Tachometer is an important tool for measuring the rotational speed of electro-mechanical machines and other rotating objects. In a closed-loop system, it should have a mechanism by which sensory instruments must be able to produce and deliver feedback values that can be fetched by the controller. Most commercial tachometers do not have such data communication features, making it difficult to be employed in closed loop systems. This study aims to develop a tachometer which is programmed using calculation on interrupt-based algorithm and has data communication capabilities as well. The algorithm

Abstract:

Accurate shaft speed extraction is crucial for synchronous sampling in the fault diagnosis of wind turbines. However, traditional narrow-bandpass filtering techniques face limitations when dealing with large fluctuations in rotational speed, hindering the accurate construction of an instantaneous phase for synchronous resampling of a shaft. To overcome this, we propose a tachometer-less synchronous sampling based on Scaling-Basis Chirplet Transform, tailored to a wind turbine’s structure and operating conditions. The algorithm generates a time–frequency representation of the vibration response

Abstract:

Computer vision techniques can monitor the rotational speed of rotating equipment or machines to understand their working conditions and prevent failures. Such techniques are highly precise, contactless, and potentially suitable for applications without massive setup changes. However, traditional vision sensors collect a significant amount of data to process and measure the rotation of high-speed systems, and they are susceptible to motion blur. This work proposes a new method for measuring rotational speed processing event-based data applied to high-speed systems using a neuromorphic sensor.

This paper contributes to an ongoing development of a micro hydropower network system tailored for implementation along river networks in Malaysia. The concept involves deploying multiple micro hydropower generators to charge a battery positioned on the riverbank. This interconnected hydropower network work alongside similar network systems to either charge larger batteries or serve multiple communities, enhancing its scalability and utility. The primary aim of this study is to determine a better generator blade type, and explore the relationship between the arrangement of generator blades in

Introduction: Cowpea decorticating is a crucial post-harvest process that involves removing the seed coats from the kernels to produce ready-to-use cowpea products such as flour, grits, and protein concentrates and food products such as Akara and Moinmoin in south western Nigeria. Methodology: In this study, a locally developed cowpea decorticator was tested and evaluated using small oloka (a Nigerian local cowpea breed) cowpea grains. The machine was allowed to run empty for five minutes before the experiment commenced. Three samples of 1kg each were weighed and wetted with same quantit

Fossil energy is running low, causing an increase in the selling price of fossil fuels. This causes the global community to become aware and consider using renewable fuels which are more environmentally friendly. Utilizing nutmeg refining waste into biopellets can be a solution for managing waste and producing alternative fuel. This research focuses on utilizing nutmeg refining waste into biopellets with a mixture of 0%, 3% and 5% tapioca flour using an extruder machine with engine rotation speeds of 1700 RPM and 2800 RPM.

Well tractor is a crucial tool in the oil and gas industry that enhances efficiency and productivity. This research aims to analyze the impact of changing the frequency of the electric motor driving the hydraulic pump on the performance of the well tractor. The experimental design involves using a well tractor with an electric motor whose frequency can be varied from 30 Hz to 60 Hz as the independent variable. At the same time, pull force and speed serve as dependent variables. The pull force on the well tractor is measured using a load cell, while speed is calculated using a digital tachomete
