Aerospace & Aviation Brushless DC-Servomotors control rocket fuel valves Extremely tough Amid tightening budgets, space agencies are increasingly looking to the commercial space sector to provide the launch vehicles of the future. Some companies now offer highly reliable and economically viable launch vehicles which can send a large variety of payloads into Earth orbit. The fuel-trim valve is located directly above the engine where the pipes of RP-1 fuel and liquid oxygen converge, to ensure a consistent drainage of both tanks.

One way to control cost is by optimizing fuel burned during launch to minimize waste. A specially developed fuel-trim valve guarantees optimum performance in this situation. It is driven by robust and reliable servomotors made by FAULHABER. Modern launch vehicles use the rocket fuel RP-1, a highly refined type of kerosene, which must be mixed with oxygen for combustion. On the launch vehicle, 4-in pipes run from tanks of RP-1 and liquid oxygen (LOX) to combine prior to entering the combustion chamber. The combustion chemistry of RP-1 is forgiving. The fuel won’t burn without oxygen, but as...

The Recon Scout IR can be thrown into a scene and operate untethered, sending back images and navigating on command for one hour or more per charge. Size is crucial Miniature unmanned ground vehicles reliably perform reconnaissance in the harshest environments, with the help of compact, high-torque servomotors It's unlikely that even the most sophis­ ticated robot can do a more effective job than a person if the task is to rescue disaster victims from a pile of rubble. A UGV (unmanned ground vehicle) such as the Recon Scout IR by ReconRobotics Inc. (Edina, Minnesota, U.S.) however can, ­n i...

FAULHABER's sister company MICROMO in the U.S. with 8 and 10 mm direct c ­ urrent motors. “FAULHABER had the best available solution in the size range we were looking for”, says Patrick McKinney, chief operating officer of Recon­ Robotics. The motors were more typically used for medical applications, which brought the added benefit of a depend­ able solution. “They have to operate in an environment where lives depend on their function”, he adds. “We've had­ these motors running continuously in tests for well over 168 hours at a 50% load. They’re very impressive.” An additional planetary...

Micro drives with the "strength of a giant" Mechanical stress test for component solder joints and bonding wires Flexibly usable Condor Sigma test device with ex­ changeable test heads. From consumer electronics to systems control, automotive technology to aviation and aerospace – today, electronics are absolutely essential in many sectors. They increasingly replace mechanical components, eliminating wear and tear and thereby extending the service life. What is easily for­ gotten in this regard is that electronics are also subject to the laws of mechanics. Mechanical test equipment is...

For electronics components, mechanical durability is no end in itself. Thermal stress, ageing or magnetic influences can also impair the fastening points of components on circuit boards. Even if the welded, soldered or adhesively-bonded points withstand the stress, the circuit path can still separate from the support­ ing board. To even attempt a quality assurance for such stresses, mechanical stress tests are essential. Special testing machines made by XYZTEC in the Netherlands, such as the Condor Sigma Series, provide certainty as to whether the construction or the soldering process meets...

Because of size constraints, it wasn't feasible to use a servo motor and encoder. Instead, Volk chose a 15 mm stepper motor in combination with a controller board. Stepper motors tend to be highly deterministic – command a step, get a step. The microcontroller determines the direction and the number of pulses applied to translate the condensing lens in and out of the optical path. The Merlin surgical viewing system consists of the condensing lens assembly and the lens positioning unit. Retinal procedures can range from re­ mov­ng a portion of the vitreous humor i that fills the eyeball to...

Brushless DC-Servomotor with integrated Motion Controller 1 Connecting cable Flange, electronics side Flange, motor side Brushless DC-Servomotor New drives with integrated functions The universe in a nutshell For years, electric drive technology has known motors that literally fit into ­­ the proverbial nutshell. Now it's about integrating drive electronics or sensors into the very limited construction space. Small, mini and micro drives - motors with just a few millimetres in diameter that manage to overcome more than just their own friction torque have long become standard items. With...
