The Cost

It is impossible to imagine any modern mechanism in any field of technology that has not been driven by an automated electric drive. In the electric drive, the main element that converts electrical energy into mechanical energy is an electric motor, which is controlled by converters and control devices in order to form static and dynamic characteristics of the electric drive that meet the requirements of the production mechanism. Equipment for the production and use of compressed air is universal and safe, it is widely used in modern industry. Compressed air is used as a source of energy, a medium for cleaning (purging), a means of transportation and even as a source of cold. Air compressors make up more than 80% of the total compressor fleet. Compressed air production and distribution systems in industry consume up to 10% of electricity. Unfortunately, there is an opinion that compressed air is cheap, although only 5-10% of the consumed electricity is spent on useful mechanical work. The cost of producing compressed air is 5-15% of the cost of production, and for some industries reach 30% or more. Reciprocating, centrifugal, and in recent years screw compressors have been widely used as air compression machines. In agricultural production, compressors are used to supply air and gases of the main or by-products of the technological cycle. These machines are common in gas supply systems. Compressors are also widely used in gas turbines. The laboratory stand for research of the piston compressor is modernized. On the basis of technical and economic indicators the electric drive system is selected, the electric motor is calculated and selected, it is checked with heating, overload capacity and start-up conditions, characteristics in statistical and dynamic modes are investigated, and also electric schemes of SAEP of the main lifting mechanism are developed. To verify the correctness of the adopted design methods, modeling was performed in Matlab.

The Relationship

Electric driving is one of the main courses in energy science. It represents the relationship between an electric motor as a tool to convert electrical energy into mechanical energy and between a managed or mechanical device that drives it through belts or gears. In the current research, a three-phase synchronous motor 1200 Watt was used to drag an electric vehicle with a rated load of 150 kg and at a speed of up to 40 km per hour. Transmission from the electric motor to the vehicle's tires is done through a gear to rotate the wheels of the vehicle. Batteries are used to store continuous electrical power from a 220-volt alternating power source using the DC/AC inverter. Solar energy 150 Watt has also been used by using a solar panel placed on the roof of the vehicle. Mechanical energy has also been used by mechanical pedal. The vehicle was tested on a flat and sloping road in Baquba / Diyala province / Iraq. The efficiency tests proved the acceleration and balance of the car are good and matched with the theoretical calculations.

And Performance

The use of electric drive for motor vehicle ancillaries is questioned when adequate power is available from the vehicle's own source of motive power. The term ‘motor’ is extended to include any electromagnetic device which converts electrical energy to mechanical energy. Reference is made to one of the earliest and best-known applications of an electric motor, i.e. the starter motor. Rotating machine construction and performance characteristics are outlined in some detail, and reference is made to applications appropriate to the machine characteristics. Simple control systems are mentioned to show their interdependence with motors as part of the application. The background and current status of the ‘disc’ motor is presented showing the advances made and the problem to be solved in the context of the motor vehicle industry. Machine rating based on the thermal stability of the insulation system with time is discussed. Life, reliability, and cost as major industry objectives receive mention at appropriate points in the text. A typical application is dissected to illustrate the process and some of the details taken into account by a designer before any calculations are made. Reasons are given to show that the application of an electric motor to a motor vehicle is almost wholly a mechanical engineering function with the basic electrical design taking an essential but minor role in the process from demand through to supply.

Railway Vehicles

An electric motor is a device that changes electrical energy into mechanical energy for railway vehicles. When developing the electric motor, it used to be developed simply for structures or control methods of the motor itself without considering convergence with other devices or technologies. However, as the railway vehicles become more advanced, technology development through convergence with other devices or technologies is spreading. Therefore, based on patent data related to the electric motors applied to the railway vehicles, this research aims to carry out technical forecasting for establishing research and development (R and D) direction for new technologies by predicting vacant technologies from the point of view of technology convergence. In other words, we studied how to find the vacant technologies in a field of convergence technology for the electric motor of the railway vehicles by analyzing the patent data. More specifically, we search the patents data associated with the electric motor of the railway vehicle that contain multiple IPC codes, and use multiple IPC codes to determine the field of convergence technology. In addition, we extract keywords from the patents data related to each of the determined convergence technologies and define the vacant technologies by interpreting the field of convergence technology and the extracted keywords.

The Stability

In the development and utilization of wave energy, the wave energy is first converted to mechanical energy, then to hydraulic energy, and finally to electrical energy. Due to the instability and randomness of the wave energy, which makes the energy easily fluctuate during the conversion process. In this paper, an oscillating wave power generation device based on hydraulic transmission system is taken as the study object, and the factors affecting the stability of the hydraulic transmission system are studied by model experiment and AMESim simulation. The results of the test show that the stability can be improved by optimizing the parameters in the hydraulic transmission system according to different wave conditions; However, the optimized hydraulic system can only ensure that the wave energy within a certain wave condition can be stably converted; when the wave condition changes greatly, the hydraulic transmission system is still easy to cause fluctuations. In addition, a Hydraulic Energy Grading Control System is proposed, which further improves the stability of the wave energy during the conversion process.

This paper investigates the effectiveness of a smart damping system consisting of a magnetorheological (MR) damper and an electromagnetic induction (EMI) device in reducing cable vibrations. The smart damping system incorporates an EMI device to reduce complexity of conventional MR damper based semi-active control system by eliminating external power sources. This is because the EMI part in the system generates electrical energy (i.e., induced voltage) from mechanical energy (i.e., reciprocal motions of an MR damper), which can be used as a power source for the MR damper. The primary goal of this experimental study is to evaluate the performance of the proposed smart damping system using a full-scale, 44.7 meters long, high-tension cable. To this end, free vibration responses and damping of the proposed smart damping system were compared with those of an equivalent passive control system. The experimental results show that the smart damping system shows better control performance than all the passive control cases.

It is known that piezoelectric material shunted with external circuits can convert mechanical energy to electrical energy, which is so called piezoelectric shunt damping technology. In this paper, a piezoelectric stacks ring (PSR) is designed for vibration control of beams and rotor systems. A relative simple electromechanical model of an Euler Bernoulli beam supported by two piezoelectric stacks shunted with resonant RL circuits is established. The equation of motion of such simplified system has been derived using Hamilton’s principle. A more realistic FEA model is developed. The numerical analysis is carried out using COMSOL® and the simulation results show a significant reduction of vibration amplitude at the specific natural frequencies. Using finite element method, the influence of circuit parameters on lateral vibration control is discussed. A preliminary experiment of a prototype PSR verifies the PSR’s vibration reduction effect.

<p><em>Abstrak <strong>- </strong></em><strong>Transformator adalah peralatan listrik yang sangat vital dalam proses pembangkitan maupun transmisi energi listrik karena transformator dapat menaikkan atau menurunkan tegangan. Pada proses menaikkan dan menurunkan tegangan biasanya sering timbul panas akibat rugi – rugi tembaga pada inti besi dan kumparannya sehingga pada kondisi overload akan menimbulkan pemanasan yang berlebih dan dapat mempengaruhi kinerja transformator. Oleh karena itu dibuat sistem kontrol temperatur pada transformer yang dapat mengontrol temperatur di dalam transformator saat bekerja pada kondisi overload, sehigga transformatornya tidak terbakar. Dial thermometer digunakan sebagai alat yang mengontrol temperatur transformator pada sistem kontrol temperatur. Agar mendapatkan sistem kontrol yang optimal, maka setting temperatur pada dial thermometer di sesuaikan dengan temperatur maksimal tranformator dapat bekerja. Sehingga pada saat temperatur tertentu dial thermometer dapat memberikan sinyal untuk membunyikan alarm dan mengaktifkan kontrol kipas sehingga kipas dapat bekerja menurunkan temperatur transformator.<em></em></strong></p><p><strong><em> </em></strong></p><p><strong><em>Kata kunci - </em></strong><em>transformator, rugi – rugi tembaga, temperatur, sistem kontrol, dial thermometer<strong>.</strong></em></p><p><strong><em> </em></strong></p><p><em>Abstract <strong>- </strong></em><strong>A transformer is an electrical device that is vital in the generation and transmission of electrical energy because the transformer can raise (stepping up) or lower (stepping down) the voltage.
