Dear readers, “Repetitive motion injuries are posing a major risk of injury in our working world today.” One manifestation of this is RSI syndrome with which highly repetitive movement sequences can lead to painful and chronic damage to the Publisher/Editor: DR.

PRECISION MONITORING & MEASURING TESTING m o v e m e n t s . INNOVATIONS move. Product life cycles are becoming shorter in all areas of industry. New products appear on the market faster and faster. This trend is particularly evident in the automotive sector. While not so long ago it still took seven to eight years before a vehicle was ready for production, today it is just two-and-a-half to three years. This places high demands on the development team. Vehicle functions, such as the frequent opening and closing of the door, must be tested quickly and precisely so that any necessary optimisations...

(Image: Kübrich) Kübrich Ingenieurgesellschaft GmbH & Co. KG develops and manufactures test systems for checking and ensuring the functionality and quality of complex mechatronic units. Together with intelligent software, well-tried hardware and high-precision mechanical components, automatically operating test systems for different tasks are created at the company...

ual drive components are optimally matched to one another, work perfectly together and thus achieve a very high level of efficiency. A brushless DC-servomotor lasts significantly longer in comparison to mechanically commutated electric motors. It consists of fewer individual components, essentially consisting of a three-phase winding (stator) and a four-pole permanent magnet (rotor) as well as the electronic commutation system. The dynamically balanced rotor provides quiet, cogging-free operation. Compact motor / gearhead combination In the described application, there are two different types...

The compact combination consists of a drive, a flexible mechanical interface for coupling, control electronics, a bus interface and a hub for the connecting additional sensor systems. (Image: Kübrich) less space. For tasks which require lower output torque, there is also the option of a plastic version of the planetary gearhead. The brushless DC-servomotors also demonstrate their reliability in the new micro-actuators for tests in the automotive sector. After all, they have proven themselves in many other applications, starting with medical engineering and camera technology to any kind of automation...

OPTICS & PHOTONICS X-RAY OPTICS radiation dose

When Wilhelm Röntgen discovered and investigated the X-ray in the late 19th century, he was one of the few pioneers in the eld who routinely used protective lead shields. He may not have known the precise reasons why, but he suspected that this kind of radiation was not good for human health – and his suspicions were well founded. Despite this, X-rays help to restore health as they are one of the most powerful instruments in medical diagnostics and, in many cases, are crucial for identifying the right course of treatment. When it comes to achieving the best imaging with the lowest possible X-ray...

SR series ∅ 8 mm, length 16 mm Torque 0.7 mNm In photography, the dynamic range describes the limits for the amount of luminance that can be recorded, or, as you could also say, the spectrum between overexposure and underexposure. The greater this range, the more details doctors are able to see on X-ray images. The technology developed by Optec has allowed the dynamic range of the lenses to be extended tenfold, from 300:1 to 3000:1. Thanks to this optical flexibility, Optec’s compact lenses can be used for both high and low sensitivity capture....

company to supply a zoom lens to be mounted on a satellite. “The lens and the zoom’s motor need to work reliably for many years under the extreme conditions in space. At the same time, every gram counts and the equipment needs to be as light as possible. Our product was the one to meet all requirements.” As with all Optec lenses, the first zoom lens in space will also be powered by a FAULHABER motor. Depending on a client’s needs, Optec can even develop and produce one-off pieces.

MEDICAL SCIENCES CHAIRLESS CHAIR

Test run at Audi: The specialist has fetched the speedometer element and is sitting comfortably on the chairless chair from Noonee during installation. "Oh, my legs! Aargh, my back!" Complaints like this are not uncommon when people have to spend a long day standing up. In many cases it is not possible to sit down at work because there must not be any chairs in the way. You are therefore on your feet all day, which can be quite uncomfortable. This can have a detrimental effect on concentration and performance. It can also result in physical complaints and more time taken off work, especially...
