A Design for a Generator

An Introduction to A Design for a Generator

We are often asked to assist with the design of generators, ranging from specifying a magnet to use through to the actual design. The level of enquiry ranges from a curiosity about the fundamentals of generator theory through to ways of getting the most from the generator and the buying of custom magnet sizes. To this extent we have produced a document about generators to act as a combined technical support document, design guide and reference booklet.

The document is a more detailed introduction to generators aimed at secondary school, university, R&D groups and companies allowing high voltage a.c. and d.c. to be generated.

If you have ever wondered how a generator actually works or have thought about trying to make and/or improve your own generator design, “A Design for a Generator” is a 50 page document aimed at answering many of the questions about generators. Written by our Technical Sales Manager (who has a PhD in the design of machines that use magnets) “A Design for a Generator” starts with an Introduction and a then an Overview of Generators (a full explanation of Faraday’s Law and how to use it at a practical level). “A Design for a Generator” shows how electricity is generated in a coil through the use of magnets, illustrating why the voltage produced is a.c. voltage and how it can be transformed into d.c. voltage. “A Design for a Generator” shows the effects of connecting coils in series and how an incorrect connection can be detrimental to the design. “A Design for a Generator” also offers an introduction to the design and theory behind multiple phase voltage outputs.

“A Design for a Generator” introduces the types of magnet materials available, the pros and cons of using each magnet material, the effects of using ferromagnetic and ironless generator designs and the theory of coil design.

After giving all the relevant background information on Generator design, “A Design for a Generator” then introduces a worked example generator which can be used as a generator for experimentation and for actual use. The design is aimed to provide around 12V through turning by hand – an achievable low speed of turning for experimental work with a reasonably safe voltage output for experimenting with. “A Design for a Generator” design concept can easily be modified to create virtually any voltage required in a.c. or d.c. e.g. 230-250V a.c., multi-phase a.c. voltages, and 24V or 48V d.c. voltages. “A Design for a Generator” illustrates with worked examples how to change the design to achieve different voltage outputs by changing parameters such as number of magnets, speed of rotation, number of coils and number of turns per coil, etc.

It should be noted that “A Design for a Generator” does not require the reader to actually make a Generator to be able to understand all the theory – the document is intended as a valuable source of information for generator design concepts with all the information required to make your own Generator as well if the reader wished to do so. A newcomer to magnetics should be able to clearly follow the theory given, the design and ways to alter the design to give different outputs. The design clearly illustrates, with pictorial guides, the method of making a Prototyping Generator including the design theory, multiple methods of changing the design to change the generated voltage and how to transform the device to a multiple phase output. The design is flexible - it allows the user to experiment with the variables of generator design theory using the same design concept – making it ideal for prototyping.

If the user wishes to make the Generator, “A Design for a Generator” gives a complete Bill of Materials list – we will supply the magnets (we recommend a minimum of 4 packs of EP646; ideally 8 packs), adhesives and magnetic test equipment (compasses and polarity checkers); the user is expected to source the other materials. The products we offer in relation to this Generator design can be found in the section we have called Products Required for A Design for a Generator.

“A Design for a Generator” concludes with a list of FAQ’s relating Generators and then introduces a list of other generator designs (including references) that use permanent magnets to give the user ideas about other ways of making a generator.

The 50 page “A Design for a Generator” is therefore a valuable combined design guide, technical support document and reference booklet. It is written to a text book standard. “A Design for a Generator” is available as a pdf file. The file size is 6.85 MB (7,190,528 bytes) – we recommend it is bought on cd if you are unsure how big a file your email system can handle. Please note that the picture has been deliberately blurred to protect the information within the document. “A Design for a Generator” is also available in a printed format.
