Punxsutawney Phil reports we still have 6 more weeks of winter
heading our way, so it's time to curl up with the February edition of
the Motors Monthly newsletter. This month focuses on selecting the right
dc motor for the right location. Effective replacement of servo motors
means knowing the inertia load of the system. It's possible to let the
motor itself provide the data needed to calculate that value. And
finally, a new torque motor design changes the game for these
special-service devices. This month's video choice is the ERockIt, an
electric motor bike you pedal to accelerate. And be sure to checkout the
new machinedesign.com
website with its growing volumes of articles, whitepapers, videos, and
webinars for the engineer.

Much has been written about the process of selecting motors for
applications in motion control. Motor selection can be complicated. The
decisions to be made include whether to employ brushless or brushed dc,
or stepper motors. A fundamental understanding of the speed-torque curve
is the key to specifying a dc motor that will do everything it needs to
do.

BX4 Brushless motor with Four-Pole
Power and reliable long service life
 What can the Faulhaber
BX4 Brushless motor with 4-pole technology do for your designs? From
aerospace to robotics to medical applications, the BX4 can deliver power
for a wide range of applications. Constructed with a modular design with
fewer parts and no adhesive bonded joints. Continuous torque up to 12.2
mNm combined with the 22F series gearhead torque increases to 1,500 mNm.

Faulhaber.

The process of tuning a retrofit servodrive on older machines can be
tedious work unless you know the load inertia of the system. The moment
of inertia of the load is a key measure for sizing and tuning
servomotors. But what if the design data is long lost or operating
conditions have changed invalidating the original data? You're in luck.
A sensor to measure load inertia is already in the machine -- the
servomotor itself.

The TMK line of torque motors from ETEL, a
Swiss firm, has 30% more torque (on average) and top speed has been
increased by a factor of 3.5 compared to the design of traditional
torque motors.

Is it a bicycle? Is it a motor bike? It's both! From Germany comes
the ERockIt, an electric motor bike you pedal to make go. The faster you
pedal, the faster the bike moves -- to a top speed of 80 km/hr (50 mph).
Stefan Gulas, the inventor of the ErockIT, states, "The pedals act as a
type of accelerator. So you don't have an accelerator on the handlebars
but you have to pedal. And the quicker you pedal the faster the motor
goes." Length: 1:50

A smooth-bodied, hygienic design lets the new Asepticplus
gearmotor meet the IP69K rating for high-pressure, high-temperature
wash-down conditions found in the food-processing industry. The hygienic
design means the motor has a smooth surface without recesses for
thorough and efficient cleaning.

The MDrive Plus product line has been expanded to include two new
step and direction units: the MDrive14Plus Microstepping and
MDrive14Plus Half/Full Step.

The IndraDrive Cs low-power servodrive is compact and supports
Sercos III, ProfiNet, EtherNet/IP, and EtherCat communications. The
drive has a universal multiencoder interface supporting Hiperface, EnDat
2.1 and 2.2, 1Vss, 5 V TTL, and Rexroth MSM servomotors.

The R7D-B Series servodrives, measuring just 120 × 35 × 105 mm,
leave room for other controls on the same rail. Real-time autotuning
eliminates the need for complicated adjustments and shortens start-up
time.

Energy Efficiency Web Conference & Expo –
May 14
Do you know you can get in-depth education on energy-efficiency and all
the benefits of an in-person trade show without ever leaving your desk
or spending a dime?
The intelligent use of energy is making headlines. Product designers and
manufacturers are striving to deliver products that consume less power,
extend battery life, generate less heat, or work from alternative energy
sources. Our Energy Efficiency Web Conference and Expo will
educate design engineers, product developers, and managers on how to
make the best use of energy-efficient product innovations and devices,
and on how to arrange them in systems to lower power consumption and
stay "green." This special one-day event will include sessions
on such areas as:
- Power-efficient drive techniques for lighting
- ROI for high-efficiency capital equipment
- Energy monitoring and energy standards
- Designing for SEMI S23 and the Energy Act of 2007
- Working with alternative power and battery technology
Make plans now to attend the Energy Efficiency Web Conference and Expo. The
event offers a full day of live webinars and interactive booths, along
with a Resource Center where visitors can download or link to additional
materials.

Collaboration is essential to successful product development in
today’s difficult economy. However, facilitating and managing the
process is growing increasingly difficult. Design teams must
participate from all parts of the world, develop products that are more
complex than ever before, and deal with product-update cycles that move
faster and faster.
Do you have the right CAD collaboration platform?
- Do you use network folders or an FTP site to manage CAD
files?
- Have you experienced trouble locating the latest versions of CAD
files?
- Are you looking for an easy way to collaborate internally?
Companies of all sizes face Product Data Management and Product
Lifecycle Management challenges. Fortunately, quick-to-deploy solutions
can help companies overcome these challenges. In this Webinar, we’ll
explore how design teams in small and medium-size companies can use
these solutions to work concurrently, find the right files, share data
and enable social product development.
