stepper - FAULHABER - DC Motors & Micro Drive Systems
are designed to harmonise perfectly with the relevant vehicle interior.
The automatic opening and closing mechanism is highly sophisticated, requiring a drive system that is equal to the challenge.
Power stepper stepper - FAULHABER - DC Motors & Micro Drive Systems and reliability: compact
combination of miniature motor and gears
One of
the key requirements of the Stepper - World of Wellness GmbH drives is their ability to "dovetail" with the relevant application both electrically and mechanically. Another
aspect to be considered is that the space for installing stepper the opening and closing mechanism of the monitors
is limited in size. This calls for small, light-weight drive
solutions that can be accom-modated as discreetly
as possible.

At the same time, superior torque rates are essential in order to cope with high leverage forces generally associated
with the stepper opening and closing of in-car monitors. And, last but not least, the drives have to be durable and reliable. After all, the opening and closing mechanism – like the complete stepper monitor itself – has to operate for many years, despite the fact that the "environmental conditions" in the vehicle may stepper often be extreme. For instance, operation of the components deployed must not be adversely affected by vibrations or extreme temperature fluctuations.
ClearLine opted for a combination of DC micromotors with precious stepper metal commutation and a robust planetary gear head in a metal design as the "driving force" behind the opening and closing mechanism of the TFT/LCD monitors. Such a compact drive unit is no more than 20 to 25 mm in diameter and can even be integrated into narrow spaces. In addition, the drive solution is more than convincing when it comes to performance.
The ultra-light ironless rotor featuring a self-supporting skew-wound copper coil gives the motors particularly good dynamics. Powerful neodymium magnets provide impressive magnetic forces.
Thanks to optimized brush materials, even extended periods of non-operation pose no problem for these "micro-masters".
The precision planetary gear head is designed to dovetail perfectly with the micromotor. Its compact construction and durability as well as its low-noise functionality are equally impressive.
Whenever you see an overhead or cockpit display open and close in a state-of-the-art motor vehicle, e.g. as part of a state-of-the-art navigation or in-car entertainment system, there is every chance that FAULHABER has provided essential technology.
Compact drives for hexapod micropositioning systems
Parallel dynamics in micropositioning
The miniaturization of mechanical, electrical and electronic components is one of the key trends dominating research and development activities within the area of drive technology. Small yet high-powered motors are capable of exploiting new opportunities in automation technology. One area that has benefited con-siderably from miniaturized drive systems is micropositioning technology, designed to under-take high-precision tasks in the most varied areas of application. Micropositioning includes basic movements with resolutions in the sub-micrometre range and paths of just a few millimetres up to several hundred millimetres.
Drawing on over 30 years’ experience, PI (Physik Instrumente) has made a name for itself as a supplier of high-performance micropositioning systems. The product highlights include pioneering six-axis parallel kinematics micro-robots which are suitable for a variety of applications.
