free - 200 watt permanent magnet wind generator - ebook
SKU: f2wpmg/ebook/000

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.

Alternator secrets - ebook
SKU: as/ebook/0/0
Binding: ebook - pdf

In the last two decades alternators have replaced generators in motor vehicles. The reasons are many: output current can be produced at lower rpm, voltage can be more accurately' controlled with solid state regulators, alternators need less maintenance, and they cost less to manufacture.

When modified, auto alternators can provide variable direct current at 0 to 120 volts for battery charging, hot charging, light arc welding, or for running AC-DC appliances and lights. Another simple modification provides AC power to run some transformer-operated appliances. If you know the secrets of its operation and the modifications possible, the small low-cost alternator can become a versatile power plant.

Surprisingly, alternators are constructed with three sets of field windings positioned evenly at 120 degree intervals inside the frame. Such construction produces three-phase AC.

Rewiring Generators as Alternators
SKU: rga/ebook/000/000

Wind generators run at fairly slow speeds: usually 250 to 600 rpm. Most people who design their own wind systems are stymied by the unavailability of slow speed generators. They usually choose to use an off-the-shelf generator that is stepped up to operating speed from the relatively slow propeller speed of a wind generator. But stepping up with gears, chains or belts introduces large inefficiencies, not to mention more moving components that need maintenance. There is another way around this problem: rewinding the alternator or generator for slow speed operation.

Batteries - simple guide to batteries - free ebook
SKU: bsg/ebook/000/00
Binding: ebook - pdf

As many small-scale methods of electricity generation are available only intermittently, some form of electricity storage or battery is needed if people want to have electricity available at all times.

There are a wide range of batteries available, and the aim of this Technical Brief is to give an introduction to the advantages and disadvantages of the different types of batteries. The central point is that there is no such thing as a universal battery; a single type of battery cannot cover all applications.

Can migrogrids make a major contribution to UK energy supply - ebook
SKU: cmmac/ebook/000

Almost all the electricity currently produced in the UK is generated as part of a centralised power system designed around large fossil fuel or nuclear power stations. This power system is robust and reliable but the efficiency of power generation is low, resulting in large quantities of waste heat. The principal aim of this paper is to investigate an alternative concept: the energy production by small scale generators in close proximity to the energy users, integrated into microgrids. Microgrids – de-centralised electricity generation combined with on-site production of heat - bear the promise of substantial environmental benefits. This is brought about by a higher energy efficiency and by facilitating the integration of renewable sources such as photovoltaic arrays or wind turbines. By virtue of a good match between generation and load, microgrids have a low impact on the electricity network, despite a potentially significant level of generation by intermittent energy sources. The paper discusses the technical and economic issues associated with this novel concept, giving an overview of the generator technologies, the current regulatory framework in the UK, and the barriers that have to be overcome if microgrids are to make a major contribution to the UK energy supply. The focus of this study is a microgrid of domestic users powered by small Combined Heat and Power generators and photovoltaics. Focusing on the energy balance between the generation and load, it is found that the optimum combination of the generators in the microgrid - consisting of around 1.4 kWp PV array per household and 45% household ownership of micro-CHP generators - will maintain energy balance on a yearly basis if supplemented by energy storage of 2.7kWh per household. We find that there is no fundamental technological reason why microgrids cannot contribute an appreciable part of the UK energy demand. Indeed, an estimate of cost indicates that the microgrids considered in this study would supply electricity at a cost comparable with the present electricity supply if the current support mechanisms for photovoltaics were maintained. Combining photovoltaics and micro-CHP and a small battery requirement gives a microgrid that is independent of the national electricity network. In the short term, this has particular benefits for remote communities but more wide-ranging possibilities open up in the medium to long term. Microgrids could meet the need to replace current generation nuclear and coal fired power stations, greatly reducing the demand on the transmission and distribution network.

Autopower - Generator Secrets
SKU: cam/gs/118/400
Binding: Softback
Lindsay Publications says - We had this a while ago, when it was called by its original title - Autopower, and it is good. Here you get secrets from the 1930's about taking a generator and converting it into a 110 volt AC alternator that could power a farm or home; the opening chapters give detailed instructions for rewinding a Ford Model A, Model T, and Dodge Type G generators. Later chapters talk about the general principles that can be applied to almost any generator. That's where the real value of this small book lies. It is not applicable to modern alternators. You must start with an old generator and go from there. Obviously, you won't use a Ford Model A or T or even an early Dodge. You'll use what you can find. And generators are still available at scrap yards on old vehicles, even on eBay at reasonable cost. Useful information. 56 page, well illustrated paperback. Lindsay Publications

Dynamo! How to build them
SKU: cam/d/278/654
Binding: Paperback: 190 pages

This book combines two titles, the first being How to Make a Dynamo by Alfred Crofts, and orginally published in London in 1900. The second is How to Build a Fifty-Light Dynamo by A.E. Watson, published in the U.S.A. in 1895. Crofts’ book is considerably the larger and more detailed, and describes the building of a DC dynamo 16 inches wide, and powering about ten 16 candle-power lamps. Mr. Watson’s book describes building a big machine with a base around 34 inches long and 20 inches wide. The drawings are better than in the first book, but may have been reduced, as you need a magnifying glass to get some measurements. The drawings in Croft’s book are not so clean anyway, and appear to be enlarged, but neither should stop you building the dynamo if you are so minded - and there is also a lot of technical information here. 192 page paperback. 51 drawings.
