The first trade show dedicated
specifically to small and community
wind took place in Detroit, Michigan
November 3–5. Denise Bode, American
Wind Energy Association (AWEA) CEO, was pleased with the turnout for the event and the increasing potential
for this segment of the wind energy
market.
Wind is the talk of the town. It has become especially relevant to the power transmission community where bearings, gears, couplings, motors and gearboxes are providing the equipment for this thriving alternative energy industry. It comes as no surprise that the Windpower 2009 Conference and Exhibition, arriving in Chicago from May 4–7, will be the largest gathering of wind energy professionals and
technologies to date.
In this paper, Edward Hage, founder of specAmotor.com, an online motor calculation and selection tool, focuses on the overheating of electric motors. Presented here is a calculation
method with which the temperature and heat development of a direct current (DC) motor and a brushless motor can be
predicted accurately.
Th e signing of a contract for more than 5,000 sets of SKF’s latest high-capacity cylindrical roller bearings (HCCRB) for wind turbines will impart added load-carrying capacity, more
reliability and longer life to the Nanjing Gear Company’s (NGC) line of gearboxes for wind generation applications.
