kg. Naturally, this performance cannot be achieved with the conventional operating specifications. Instead of the standard operating voltage of 6 V, the motors are operated at 10 miniature motors miniature motors - FAULHABER - DC Motors & Micro Drive Systems V.
In order to avoid pushing, the robots must be able to brake quickly.
As a EXPO21XX - MOTION21XX - HALL 05 : Micro and mini motors result, the motors are subject
to a short-term counter-voltage of up to 20 V. Despite this "overload", the motors in the robots have operated problem-free
miniature motors for four years, i.e. several hundred operating hours. Demagnetisation, bearing damage, carbon consumption or unsoldering of the armature
coil on the collector – problems that may occur in
low-budget drives developed by other companies –
are simply not an issue with the "souped-up" FAULHABER solution. The micromotor’s "fitness" level is miniature motors world class, as one would expect from a
champion. Boasting impressive performance in a small footprint, FAULHABER micromotors are the perfect choice for a range of applications – even those miniature motors that are slightly more "unusual". Many years of experience, combined with state-of-the-art materials, are the basis for outstanding results. Perfectly miniature motors synchronised pulse generators and gearheads are an advantage not only in robot football but also in industrial applications, an area in which compact design and performance are often essential. The miniature motors highly reliable and durable components also reduce operating and maintenance costs – the perfect solution for applications that require maximum efficiency until the final whistle has been blown.
The smallest drive system in the world
Precise positioning with 1.9 mm diameter
Micro-drives are the highlights at technology fairs. While just a few years ago there were only laboratory prototypes of motors available, FAULHABER is now successfully mass-producing entire micro-drive systems, comprised of a micromotor and planetary gearhead with a diameter of only 1.9 mm. At this year's Hanover Fair/MicroTechnology a new motion controller was presented for this system, which – for the first time – allows precise motions for a drive of this size. Due to a special type of motor actuation, speed profiles can be preset exactly, and positions can be approached with pinpoint accuracy. Together with "Motion Manager 2", a convenient user interface for motor controls, the user has at his disposal the same functionality as with larger drives.
The brushless DC micromotor is based on the same successful technology as its "big brothers", and its excellent power-to-volume ratio is truly impressive. It consists of a housing containing a coreless coil with skew winding as the stator and a 2-pole NdFeB magnet on a continuous spindle as the rotor. Electronic commutation without brushes ensures a long service life. The dimensions are: dia. 1.9 mm, length 5.5 mm – together with the gearhead 9.6 mm. The micro-planetary gearhead (also dia. 1.9 mm) was developed with a special involute gear toothing, and it generates torque up to 150 µNm.
The motion controller ...
Even a high-performance motor can only work as accurately as permitted by its actuation system. For this reason a special electronic actuator was developed to complement the micromotor. The new Motion Controller MCBL 05002 makes it possible to set all the motor parameters individually, as is state of the art with larger drives. Not only can rotary speed and torque settings
