...Permanent Magnetic Generator Construction Manual http://HoJoMotor.com Our Team Doing an On-site Assembly in Peru http://HoJoMotor.com Section 1) Introduction This manual describes how to build a 'permanent magnet generator' (PMG). We can also call it an 'alternator', because it generates alternating current (AC). It will not generate 'mains voltage' or 'utility power' AC. It generates low voltage, 'three phase' AC, and then changes it into 'direct current' (DC) for charging a 12 volt battery. What this PMG is made of 1) EXPLODED PMG The PMG (see diagram 1) consists of: • • • • A steel spine and shaft. A stator containing coils of wire Two magnet rotors A rectifier The stator contains six coils of copper wire, cast in fiberglass resin. This stator casting is mounted onto the spine; it does not move. Wires from the coils take electricity to the rectifier, which changes the AC to DC for charging the battery. The rectifier is mounted on an aluminum 'heatsink' to keep it cool. http://HoJoMotor.com The magnet rotors are mounted on bearings, which turn on the shaft. The rear rotor is behind the stator, and enclosed within it. The front one is on the outside, fixed to the rear one by long studs which pass through a hole in the stator. The wind turbine rotor blades will be mounted on the same studs. They will turn the magnet rotors, and move the magnets past the coils. Magnetic flux passes from one rotor to the other through the stator. This moving magnetic flux...

...(Patterson, 2014) In this small article that is up for discussion, I will be bringing foresight of understanding about Flying Wind Generators. In ways it is better than resourceful energy such as your free standing windmills or even such as standby generators. This is exactly what the name states a flying wind generator better known as BAT (buoyancy airborne turbine). Just think of all the places in the world that is struggling due to the prices or material needed to produce mass electric. Most of these places have the use of windmills which only pick up so much wind with the height that it stands at. Another resource of power is a standby generator, into which you are burning resources such as diesel or any other fossil fuels that are harmful to the environment. Do you believe there are better ways to generate power for numerous of housing or businesses. Of course there is and this BAT I shall give you my perception. According to CNN This dramatic idea its a dramatic idea that could change the course of countless of lives around the planet. This BAT which is 35 feet wide and can be folded up and stored for traveling in a container is lighter than any other electrical resource. It flies at an altitude of just about 1000 feet above ground which does not affect wild...

...(DPC) strategy for a doubly-fed induction generator (DFIG)-based wind energy generation system. The strategy is based on the direct control of stator active and reactive power by selecting appropriate voltage vectors on the rotor side. The proposed direct power control (DPC) method produces a fast and robust power response without the need of complex structure and algorithms. Literature review________________________________________ There are two major classifications amongst wind generation units: fixed speed generation and variable speed generation. The fixed speed generators have a design speed for which they have maximum efficiency whereas for other speeds their efficiency is lower. But variable speed generators have the maximum power tracking capability that extracts maximum available power out of the wind at different speeds thereby resulting in more efficient operation. Also the variable speed generators reduce mechanical stresses on the turbine thus increasing the lifetime of the turbine. It also helps damp out oscillations in torques more efficiently. Thus variable speed generators are more commonly installed Fig.1. Block diagram of DFIG based WECS Amongst the variable speed generators there are two major kinds, synchronous generators with direct power electronic converters and doubly fed induction generators with rotor side power electronic converters. Both have the above mentioned advantages of variable speed generators but the power electronic ratings of the...

...| Generator | | | | | | When a company such as Generator decides to invest in a foreign market with distinctly nondomestic cultural norms such as China and Thailand, it would be well served to investigate and develop a negotiation and communication strategy that will mitigate these differences in a way that will not unduly jeopardize the success of its new endeavors. While they considered the differences in the legality of their overseas standing, it is obvious that Generator failed to develop a plan that accounted for the cultural hurdles before entering into these partnerships. By entering into these partnerships they effectively mitigate the limitations of corporate ownership in these countries. In contrast, their lack of understanding and adapting to foreign ways of thinking has resulted in the potential alienation and humiliation of their partners. With their failure to proactively administer to these cultural differences Generator must now address these issues downstream. Ideally they would have fashioned their forward-looking communications in a manner that acknowledged the difference between Chinese and Thai culture and approached them from two different standpoints. By segmenting one country from the other they will have the opportunity to facilitate constructive negotiations that are culturally aligned with their intended audience. This would also encourage them to not group all Asian cultures together and repeat mistakes that they have made...

...Electric Generator Juman Haffar Michael Faraday Michael Faraday was born on 22 September 1791 and died in 25 August 1867. He was an English scientist who contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis. Faraday’s family was not well off. He received only a basic formal education. When he was 14, he got a job in a bookstore, and spent all of his time reading books. In 1813, Faraday got the job of the chemical assistant at the Royal Institution. In 1831, Faraday discovered electromagnetic induction, the principle behind the electric transformer and generator. This discovery was crucial in allowing electricity to be transformed from a curiosity into a powerful new technology. During the remainder of the decade he worked on developing his ideas about electricity. He was partly responsible for coining many familiar words including 'electrode', 'cathode' and 'ion'. Faraday's scientific knowledge was harnessed for practical use through various official appointments, including scientific adviser to Trinity House (1836-1865) and Professor of Chemistry at the Royal Military Academy in Woolwich (1830-1851). However, in the early 1840s, Faraday's health began to deteriorate and he did less research. He died on 25 August 1867 at Hampton Court, where he had been given official lodgings in recognition of his contribution to science. He gave...

...The first process that we must address is who, or whom the stakeholders are. The stakeholders in this situation are: firstly the parents, the children that will be attending the schools, residents that are around the schools, businesses that are in the area of the schools, teachers and the school officials, and finally the school district. Objections to be considered about the redrawing of the school district’s boundaries plan are: • Quality of education • Increased travel time • Crossing economic and cultural boundaries • Affect on property values • Social effects on children School officials will have to address each one of these objections in order to make the parents, students, school’s faculty, outlying businesses, and communities feel at ease with this new transition. When negotiating this scenario to support the school board’s need to have boundaries redrawn is to use a diagram showing the key points of the school boards concern and explaining all the points in detail to the stakeholders as to why the school’s boundaries being redrawn. The points for each concern that the board has would show the negative effects that may happen if redistricting is not implemented. The points that the board would have to address and are not limited to are: • Overcrowding of the schools o Quality of education o Inadequate facilities o Fire, hurricane, earthquake, bomb threat, etc. evacuation plans o Transportation times (buses...

...INTRODUCTION: A synchronous machine rotates at a constant speed in the steady state. Unlike induction machine the rotating air gap field and the rotor in the synchronous machine rotate at the same speed called the synchronous speed. A synchronous machine can operate as both motor and generator. They are used primarily as electrical power generators. They are usually large machines generating electrical power at hydro, nuclear or thermal power stations. Synchronous generators with power rating of several hundred MVAs are quite common in generating stations. Synchronous generators are the primary energy conversion devices of the world’s electrical power systems today. Because the rotor speed is proportional to the frequency of excitation, synchronous motors can be used in situations where constant speed drive is required. In industry, synchronous motors are used mainly where constant speed is desired. In industrial drivers, therefore synchronous motors are not as widely used as induction or dc motors a linear version of the synchronous motor (LSM) is being considered for high speed transportation systems of the future. An important feature of the synchronous motor is that it can drop either lagging or leading reactive current from the ac supply systems. A synchronous machine is a doubly excited machine. Its rotor poles are excited by a dc current and its starter buildings are connected to the ac supply. The air gap flux is therefore the resultant of the fluxes due to both...

...analysis, the power system network to be studied is designed and simulated using the software, CYME 5.02 Power System Simulation Software. The system chosen for the study is that of a two machines system, involving two synchronous generators connected to a substation grid through circuit transmission lines. In order to gain much further comparison of the results, it is considered also the two different types of synchronous generators’ rotor types, salient-pole rotor and non-salient pole (round) type rotor. Transient stability studies are associated to the effects of faults on the synchronism of the generators. These disturbances may include faults on loss of load, loss of generation or loss of system components such as transformers or transmission lines. When fault is applied, the power generated from the nearby machine is reduced, producing speed differences during the time interval of the fault occurrence. Fig 1. Two machines system When the generator electrical load is suddenly increased, the electrical power exceeds the mechanical power input. This power deficiency is supplied by the kinetic energy stored in the rotating system. The reduction in kinetic energy resulted turbine speed to drop and as well as the frequency of the generator. This change of speed can be adjusted by a governor, which is an attachment to a machine for automatic control or limitation speed; it controls the energy through the prime mover to control its power. Governor changes the input valve...

...be no less than 50% of the maximum flow during a given calendar day. The existing generating units were typical fixed-blade propeller turbines with a very narrow range of efficient operation, so they could not effectively meet this new requirement. We Energies evaluated several options for addressing the new operating regime including spilling the required low flow when necessary, installation of a minimum flow turbine-generator unit, and conversion of one of the propeller units to full adjustable blade Kaplan operation. The Kaplan conversion was chosen as the most effective option to improve the operating efficiency and flexibility of the plant while achieving the required low flow operating capability. This paper describes the Owner’s planning process that resulted in the decision to convert the unit from fixed to adjustable blade operation. The conversion not only replaced the turbine runner but required the integration of a blade control system to work with the existing governor. In addition, the mechanical and electrical capabilities of the existing generator were evaluated to address the increased turbine output and higher overspeeds. The hydraulic and mechanical design aspects...

Cogeneration is possible using the cooling water that maintains the cold sink, so heat-and-power systems for homes are provided. With higher efficiencies, their quiet vibration-free operation, very low emissions when burning natural gas, simplicity, and potentially high reliability could make the Stirling engines an attractive alternative in the near future [6]. Simulation and modeling can be used to evaluate the operation of the solar Stirling engine based power generation systems. Considerable research has been performed on the modeling and control of Stirling engine systems. Most of this research, however, has been done using mechanical and thermal models of Stirling engines that neglects the electrical parts of the system [5], [7], [8]. In this research...

...huma/mechanical energy or pedal power with the use of our Bicycle Charger. A Pedal Powered generator provides a method of generating electricity by means of a modified exercise bike for use in energy storage and running portable devices. Human.mechanical energy is converted by a belt-liked cloth to a bike dick brake. The energy created by the DC generator can be stored in various types of lead-acid batteries. Energy stored in battery form can act as a supplemental energy source for battery banks that may already bu used for wind, hydro and photovoltaic systems. Also, energy that is stored within the lead-acid battery can be utilizrd as DC current for use in DC appliances such as those found in automotive mobile homes. If Alternating Current (AC) appliances are in place then an inventer must be used to transfer the 12 volts of DC current into the standard 110 volts of AC current for usage by these appliances. Pedal power is the source of getting energy from humans. It can be described as the transfer of energy generated through the movement of human feet and hands in some cases. Humans used the pedal power to impel bicycles for centuries. In the primeval time all the machinery was manual and required the physocal energy to run them. This use of pedal power proved to be really helpful to perform even hard labor tasks. Pedal power was the base of the industry for many years. The idea of pedal power generators emerged from the wind turbines. Recent trend towards the use of bicycle again has...
