The obsolescence of materials and processes in the manufacture of traditional DC brush gearmotors has necessitated the development of an upgraded DC brush gearmotor.
In this special news section, the editors of Power Transmission Engineering have gathered the latest product news
and information from the gears and gear drives sector.
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.
Despite posting its slowest quarter
since early 2007, AWEA remains
optimistic that the wind industry can
and will work successfully with the
revolving doors in Washington.
In order to make better purchasing
decisions about centrifuge applications,
one must understand the concept of
centrifuges and the drives that operate
this equipment.
Much of the industrial energy being
consumed by systems is wasted through inefficiency. For this article, a system will be defined as the following components working together: electrical input power, variable frequency drives, induction motors, gearboxes and transmission elements
(chains, belts, etc.).
Robotics and other advanced automation technology systems are viewed as a looming threat to some in the plant
maintenance field. Although there is
a constant battle for some workers to
remain useful while machines are continuously fulfilling more roles on the plant floor, there are those who in turn have found a better use of their newly freed time.
