Talk about a maximum use for solar energy. While scientists have
shown that objects can be lifted by light alone (which in itself sounds
like science fiction), the ambition of many researchers is to create a
machine that is even more than light-switchable - one that uses a motor
powered by light, directly converting input energy to rotation and
taking out the middleman.

Austriamicrosystems reveals a brand new magnetic rotary encoder that
is, quite simply, meant for brushless DC motors in automotive
applications. With an 8.5-bit resolution, the AS5134 can recognize 360
positions within one 360° turn and is accessible with either a serial
or a PWM (Pulse-Width Modulation) interface.

Meet Deena, an X-Y-Z robot that uses three different versions of the
RGS 10000 slides leadscrews from Kerk Motion Products
Inc. While preparing samples to be tested for mercury and other
metals, Deena requires a precise ability to position the samples.
Designers broke with tradition and opted for slide leadscrews – check
out the results.

The EC16 brushless dc motor measures 16 × 56 mm, is rated to 40 W,
and has a 0 to 60,000-rpm speed range. Lower speeds and a corresponding
high torque are possible using a planetary gear. The unit is designed to
separate the control and main magnets. This protects the electronic
commutation Hall sensors from interference of the magnet and winding
current. Advantages of the motor include high efficiency, no cogging,
and the large linear speed/torque gradient.

The MLN50 Mechatrolink-II five-phase stepping motor and driver
system offers full programming-command functions and up to 10 Mbytes/sec
communication data rates with a maximum 50-m transmission range.
The 100/200-Vac driver system is designed for operation with the
company’s high-torque, CE-rated five-phase stepper motors in various
NEMA sizes.
The stepping system uses a high-performance pulse generator chip, the
MPG1032, to execute advanced operating functions including fast-forward
positioning, interpolation feed, and home. The unit provides high-speed
network integration with NanoDrive high-resolution positioning stepper
systems, which lets users develop their own motion field network.
Additional features include: external input positioning with speed,
acceleration and deceleration parameters setting, and linear and S-shape
acceleration and deceleration switching selection with onboard Serial
EEPROM, which can be rewritten 100,000 times.

Attention time and information starved engineers
Now you can get a quick dose of literature, product, and digital
information resources right in your copy of Machine Design Magazine.
Look for your edition of Literature Express in the second issue of May
of Machine Design. There you can request product information, catalogs,
CD’s and more from hundreds of manufacturers.
Rev up your interdisciplinary design skills
What happens when a microcontroller turns on a power FET, sending a
current pulse to a motor coil that develops a magnetic field which turns
the rotor shaft, advancing a timing belt that drives a pair of nip rolls
suspended on bearings in a web-processing operation on a form, fill, and
seal machine installed on a potato chip line at a Frito Lay plant in
central California? And how can you be sure that the encoders, prox
sensors, and other feedback devices you plan to use will accurately see
and report every relevant motion, machine state, and process condition?
And will the signals get through the networks fast enough, without being
corrupted, giving the controllers time to execute their algorithms as
intended? It's a lot to think about, and it only scratches the surface
of what many engineers grapple with today. If you happen to be one of
them, then the place for you — where you can find answers and meet
others with similar concerns — is www.Mechatronic-Design.com.
Backed by some of engineering's top information sources including

Supercharging Products with Embedded RFID
Sponsored by SkyeTek
DATE: June 26th, 2008
TIME: 2:00pm ET/11am PT
The power of RFID as a stand-alone application to increase accuracy and
efficiency in supply chain management has garnered much attention in
recent years. The story now is how RFID can be added as a feature to an
almost unending list of products -- adding new functionality, increasing
reliability and enhancing the user experience. They may still look the
same on the outside, but embedding RFID readers and software into
existing and yet-to-be released products can transform them on the
inside offering manufacturers, OEMs and product designers new
opportunities for competitive advantage through increased efficiency,
accuracy and product differentiation.
