One of the main hurdles facing the event of higher, bigger wind turbines is the way to grow larger without becoming heavier and more cumbersome. The manufacture, assembly and transportation of wind turbines is already expensive and requires special machinery to handle the massive loads, but if we would like to supply more power from wind, making larger and more powerful turbines is important . GE is looking into fabric-covered turbine blades that might be lighter even in greater sizes, but there are more possibilities to explore.
Wind technology company Boulder wind generation has come up with a stimulating thanks to make powerful turbine generators without adding weight. The start-up has created a generator that's inspired by printed circuit board design.
Gigaom reports, "A generator's engine is framed from a turning segment called the rotor and a stationary part called the stator. During a typical generator today, both the rotor and therefore the stator are made with iron wrapped with copper coils to make the magnetic flux for producing energy, which can then be converted to electricity.
But what Boulder wind generation has done is to engineer a special quite stator by printing copper wires onto fiber glass and laminating layers of fiber glass together to make a stator that appears , and works, sort of a computer circuit board, said Andy Cukurs, the startup’s CEO. This design doesn’t use iron, but it does add a magnet to the entire generator to make that magnetic flux. Within the end, what you get may be a stator sandwiched between the magnet-lined rotors."
What results may be a generator for a 3MW turbine that might weigh 40 percent but conventional generators. For a 200 ton tower, that would mean a weight investment funds of 6 - 10 tons which weight reserve funds converts into cost investment funds for assembling and moving breeze turbines. Be that as it may, this technique is good if you need to make many copies of the circuit and also can produce Best Quality Printed Circuit Board Layouts.
It's also more efficient and ready to operate at lower wind speeds. As Boulder wind generation states on their website, "The BWP design eliminates the mechanical losses related to a gearbox, while leveraging the upper efficiencies at lower operating speeds enabled by static magnet rotor excitation."
The company is functioning on a prototype of its technology for a customer that ought to be ready within the next year approximately. That unnamed customer will test out the planning and make an order for more if all goes well.
