Wind-generated electricity in some locations is close to the cost of power from conventional utility generation. Wind power, the world’s fastest-growing energy source, will provide industry, businesses, and homes with clean, renewable electricity for many years. So in keeping with this year’s theme at NPE (National Plastics Exhibition) 2009 in Chicago of “Energy Efficiency and Renewable Energy” along with “Going Green” HPM America unveiled its newest product line – WIND TURBINES.
Introducing this line of turbines lets HPM America, Mount Gilead, Ohio, address the needs of home owners, businesses, schools and universities, governmental institutions and other applications. The new turbines will be available from small 1kW units to 1MW versions. People throughout the world are advocating for wind turbines and their positive effects on the environment. HPM America says it is devoted to helping people purchase and attain wind power electricity sources.
HPM says its turbines will use Axial Flux Permanent Magnets (AFPM) which generate power more efficiently and at lower wind speeds due to its coreless technology. The generators eliminate traditional cogging issues, making them ideal for wind turbines.
In addition, the generator design eliminates need for a gearbox as part of the unit’s drive train, thereby minimizing down time and reducing maintenance costs over the life of the system.
In AFPM generators, a coil wraps around a specially designed disc at the center axis. Magnetic discs then rotate on the sides of the coiled disc and generate electricity. This kind of power generating technology is ideal for generating power from the wind because its initial operation torque (cut-in speed) is lower than the often used Radial Flux Permanent Magnet (RFPM) method.
AFPM power generation is classified into two configurations, the inner type and outer type. In the inner type configuration, only the magnetic disk rotates while the generator housing remains fixed. In the outer type configuration, the whole generator body rotates by fixing the magnetic disk to the body. Both configurations can be provided depending on the application specifications.
When the generator is producing electricity, it also produces heat, and as heat increases, generator efficiencies decrease. To solve this problem, HPM generators are liquid cooled. This significantly reduces associated wear that high-temperatures can cause, and thus improves the generator’s life-span. What’s more, the company says the price point on its systems ensures a faster return on investment to the end user.
HPM America manufactures and supplies extrusion systems, injection molding machines and die casting equipment along with providing contract manufacturing from its headquarters in Mount Gilead, Ohio, U.S.A. HPM America maintains offices in Sao Paulo, Brazil and Chennai, India along with a network of manufacturer representatives and consultants that cover Mexico/Latin America, China and the Pacific Rim, and Europe. In the U.S. and Canada, HPM works directly with customers.
