We're almost through the first month of MACHINE DESIGN's The World's Smartest
Design Engineer competition. You score points as you correctly
answer engineering questions while competing against other engineers
around the globe for fun, prizes, and the prestige of being The World's Smartest
Design Engineer. Prizes are awarded monthly, so if you haven't
started yet, April 1 kicks off a whole new round of competition. Sorry,
but prior month winners are not eligible for the new round. But keep
playing to boost your score for the yearly grand prize! Challenge your
friends and colleagues to a grudge match! Remember, the monthly
competition for The
World's Smartest Design Engineer starts anew in April! In the
meantime, keep reading Motors Monthly and MACHINE DESIGN
magazine -- you'll never know where questions may come from! (Hint!
Hint!)
-- Robert Repas, Assoc. Editor
You can follow the search for The World's Smartest Design Engineer on
the MACHINE DESIGN Blogs, LinkedIn,

When engineers select couplings with the capabilities, environmental
resistance, and service parameters their applications demand and install
and use them as designed, they can be confident the couplings will work
reliably over their designed lifetimes. Unfortunately, ignoring one or
more of these factors can cause premature coupling failure with results
ranging from small inconveniences to serious financial loss and personal
injury.

Researchers at Purdue University, West Lafayette, Ind., impregnated
a piece of ordinary paper with a mix of mineral oil and nanoparticles of
iron oxide. The result, dubbed Ferropaper, can be moved using a magnetic
field, possibly making it useful in speakers, tweezers capable of moving
a single-cell, low-cost micromotors for surgical instruments, and other
applications.

As rotating machines face more-demanding life, speed, temperature,
and pressure requirements than ever before, standard seals made from
conventional materials find it hard to keep up. Potentially damaging
process fluids and gases further challenge seals. The result: high
premature-failure rates in seals, machine breakdown, and escalating
repair and warranty costs.

In celebration of its 50th Anniversary year, Bison Gear &
Engineering Corp. is offering over 30 models of metric worm gear
reducers for only $50 each. These hollow shaft right angle gearboxes are
designed to mate to IEC standard motors in frame sizes from 50 to 80.
Using hardened steel worms and forged bronze gears with reductions from
7:1 to 100:1, the lifetime lubricated gearboxes are rated for input
powers from 1/20 to 2.25 hp (.04 to 1.67 kW), with continuous torque
ratings up to 708 in.-lbs (80 N-m).

The RSBS Series single-phase plug-and-play soft start reduces the
starting current of heat pumps used in residential installations. The
soft start limits amperage demand, which peaks when single-phase scroll
compressors of the type used in heat pumps start. Maintaining starting
current below fixed limits lets the RSBS avoid high-energy tariffs.

The VLT low-harmonic drives ensure high-quality sine waves from the
power-supply grid by actively imposing currents, as needed. The drives
come in 132 to 630-kW high overload, 160 to 710-kW normal overload, and
voltage range of 380 to 480 Vac, 50 to 60 Hz.

The SCR100 is an ultrahigh precision, single-axis stage that
integrates a slide guide, encoder, and linear-shaft motor. The stage’s
moving-magnet design, locates all cables and connectors in the
stationary base. The resulting absence of any moving cable eliminates
motion errors due to cable forces.

Efficiency Loss & Capture in Mechanical Gearboxes and Motor
Systems
Sponsored by Wittenstein
DATE: April 15th, 2010
TIME: 2:00pm ET/11am PT
Make a large impact on system efficiencies through gearbox and motor –
whether in new designs or existing machines. The heart of any motion
system is the motor and delving into the mechanical components around it
play an integral part in optimizing overall system efficiencies,
providing designers with energy and cost savings. Having introduced the
world’s first low-backlash planetary gearbox, Wittenstein has spent 25
years on developing and identifying mechanical and electrical
specifications.

Cable Basics: Sizing and Selection
Standard vs Custom Cable for OEM Applications
Sponsored by Northwire Inc.
DATE: April 22nd, 2010
TIME: 2:00pm ET/11am PT
OEMs are pushing engineering teams for the fastest development cycle
possible. Component selection errors can cause big delays and
reliability issues after the products are in the hands of customers.
To help engineers make the best cable decision for their projects,
Northwire is teaching a technical course that dives into the key issues
that affect cable performance and the final cable solution attached to
the project.
