Three Phase Synchronous Generator

Build from scratch? Building from scratch would require some iron, carbon and silicon for the steel rotor frame and base, copper for the wire, hopefully you can buy bearings and journals already made... silicon again for some integrated circuits, SCRs, diodes etc. to make a controller ... how far do you need o take this?

You need to determine a number of things before you start.

Like;

Power Output?

Directly driven or inverter?

What is going to drive it? Petrol Motor, Diesel Motor, Water wheel or Wind?

What duty cycle and at what loading?

Manual or automatic start.

Portable or fixed installation?

Will this be a one off or potentially a commercial product?

How critical is the COTS requirement? Or does it need to be bespoke?

What are the regulatory requirements for putting it into service?

A tad more detail as to your requirements will provide bettter answers..

Wouldn't, " what equipment to buy and how to build step by step" be the homework assignment you have been given?

What will you learn if we design it for you? Then tell you how to build it.

Write when you get work.

Piffle, this is an engineering blog. Assembly work is done now in third world countries. Real engineers don't assemble!!

You should instead be delving heavily into Maxwell's Equations and learn the intricacies of multidimensional vector space mechanics. This will then show you how these equations transform into laws of Electromagnetic Induction. This will give you the fundamentals so that you can design your own generator. Don't think that this will only be useful for calculating the number of turns the stators must be wound. These equations will also teach you how to minimize eddy currents in your magnetically permeable material, what shapes your magnetic material should be and how you can control the output voltage by modulating the magnetic field strength. If your careful you'll even learn where the stored magnetic energy exists.

But if you're really ambitious, you could delve into the realm of metallurgy to understand which materials will work best for extruding your wire, which metals will magnetically quench sooner and how to increase the hardness of your bearings. With the electromagnetic experience in your repertoire, you can now even understand why some generators will have ceramic bearings. But don't forget, to properly steer your currents you should have a good understanding of chemistry so that you will know where and how poorly conducting materials are necessary in a good generator design.
