Hot cocoa to warm December's chill is just the ticket while you curl
up with the latest Motors Monthly newsletter. This month we look at
installations that reduce cable congestion, new FEA software for motor
design, and an XY-position table that uses an interesting stepper motor
design. The featured video takes a look at what goes into rebuilding and
rewinding electric motors. And our usual selection of new products help
to make your job easier.

Precision-positioning applications often employ multiaxis-stage
technology. A simple arrangement of mechanically stacked stages is a
reasonable and economical installation. However, the downside is that
cable management often becomes a problem. A way around the problem is to
replace the central multiaxis controller with single, separate control
modules, each mounted directly to an axis. A simple network connection
than links and synchronizes all controllers.
|
A downside to FEA design is that building models can take a lot of
time. Analytic software for motor design does not provide enough
accuracy and precision. However, Opera Electrical Machines Environment
is an application specific variant of a general-purpose electromagnetic
FEA tool. It helped speed the building of models with ready-to-use
templates for common motor types.

A line of dual-axis linear motors from Baldor Electric Co., Fort
Smith, Ark., the HoneyComb Series, uses a novel linear-stepper-motor
design to drive an XY base. The motor comprises two parts, a forcer that
generates motion and a base or platen that performs two-axis moves.

This video, from Jasper Electric Motors, details the steps they take
to rewind and rebuild electric motors. They handle electric motors of
all sizes from fractional to several thousand horsepower.

New versions of the EtherCAT-enabled AX5000 servodrives now come in
18 and 25-A rated current. The Series supports highly dynamic
positioning tasks and its high-performance communication permits
interfacing with PC-based control technology.

The fractional-horsepower VWDIR83 gearmotors perform as drop-in
replacements for the Von Weise VW83 Series of stationary and portable
low-voltage motors. Six models each cover 12 and 90-Vdc inputs.

The compact J1000 ac drive features a standard internal braking
transistor for overexcitation braking, lifetime monitors that
continuously monitor key components, and the ability to operate a larger
motor with the normal duty rating.

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.
