Given that many different hydraulic systems recommend the use of either frequency converters or cyclic control (soft starter technologies), the question must be asked - Which one of these solutions is the most cost-effective in reducing energy consumption and providing the most satisfactory payback time?
A new solution has been developed around
the use of microprocessor-controlled
prostheses. Just like natural limbs, these
can react automatically, adapting to the
current situation.
The Baldor Reliance RPM AC Cooling Tower Direct Drive Motor is designed exclusively for the cooling tower industry. This motor combines the technologies of the power-dense, laminated frame RPM AC motor with high performance, permanent magnet salient pole rotor designs.
While safety functions have been integrated into drives packages for some years now, the current trends are very exciting, from many angles. Today,
a full complement of safety functions can be implemented at the front-end of a system design on all types of production machines, including printing, packaging, converting,
materials handling and other equipment used throughout American industry.
Suggesting a bicycle is environmentally
friendly is stating the obvious. But
the Copenhagen Wheel, unveiled at the
2009 COP15 United Nations Climate
Conference, is taking green technology
and cycling in a new direction.
During the qualification campaign of the NIRSpec (near-infrared spectrometer) instrument mechanism, the actuator could not achieve the expected lifetime that had been extended during the development phase. The initial design could not be adapted to the requested number of revolutions during that phase. Consequently the actuator needed to be modified so that the function of the mechanism would not be
endangered or, by extension, the overall function of the NIRSpec instrument. The modification included a
change of the overall actuator design—internal dimensions, tolerances, materials, lubrication and assembly
process—while keeping the interface to the mechanism, mass and function.
