High-precision drives answer aerospace demands

Maxon Motor UK product story

Maxon Motor will be showing off a selection of its impressive high-precision drives at the Farnborough Airshow from 14th to 20th July 2008.
With an almost legendary reputation for reliability, the Maxon range of high-precision drives and systems is fast becoming as familiar in aerospace development as it is in so many other endeavours where component failure is simply not an option.
In the highly competitive world of commercial airlines it is essential that passenger comfort features can be counted on to operate reliably at all times.
Success depends heavily on providing passengers with a pleasant, comfortable flying experience - every time.
Motorised features such as a TV screen that descends from the ceiling, and blinds that can be raised and lowered effortlessly, all add to that experience.
So too does efficient and reliable valve control for the toilets, and the motorised adjusting mechanism in a growing number of airliner seats.
One recent issue of concern to airline designers has been that hot air drawn into a plane's heating system can become contaminated with toxic substances released when oil seeps through seals and is burned by the engines.
This poisons the air that the passengers breathe.
A solution now being applied is to draw air through inlets on the wings, separate from the engines.
The control valves for that system are operated by motors that need to be dependable at temperatures as low as -50C.
But when you consider that the Maxon motors on the NASA Mars rovers work at temperatures as low as -120C, that is not a problem.
While reliability is top of the designers' list of priorities, low noise and low weight are two other important considerations.
Smooth, quiet motor performance is all part of ensuring comfort, and lightweight design in all systems contributes to fuel economy.
And when it comes to systems involved in actually flying the aircraft - the autopilot equipment, for example - high precision is obviously a must.
Needless to say, Maxon drives and systems meet all of those demands.
This year at Farnborough, Maxon will introduce an all-new design of planetary gearhead that is incredibly quiet in operation.
The company will also exhibit a representative sample from its massive current range of 147,000 dependable precision motors, gearheads, encoders, controllers and other components.
Visitors to Farnborough will be able to request free copies of the latest Maxon catalogue.
Designed not just as a sales catalogue but as an essential reference work that should be on every engineer's shelf, each copy also contains a free CD-ROM that holds the same information plus the Maxon electronic selection program.
In most cases it should be easy to choose the most appropriate components for any particular system by referring to the data presented.
Useful advice, diagrams and formulas are given to help in this process.
The Maxon selection program takes this further by automatically identifying individual products, and combinations of products, that closely match the design's requirements - with no need for laborious manual calculations.
It's even possible to take CAD images of Maxon components and drop them straight into the design.
But while information technology is a vital tool, Maxon recognises that some problems require the help of a human being.
"At Maxon Motor UK we have a team of highly qualified and experienced product engineers, ready, willing and able to work with designers on their projects - and they will be on our stand at Farnborough", says CEO Keith Ellenden.
"They are all engineers, just like our customers, and they really love a challenge".
"They will come out to look at the project, do the calculations and present the solution".
"And if the answer doesn't lie within our 147,000 off-the-peg solutions, we can create one that's tailor-made".
