Braking Toward the Future
In the past decade, electrohydraulic braking systems--including ABS and traction control--have grown increasingly popular, due largely to the vehicle design flexibility and performance advantages they offer. The industry has seen several other instances of intelligent machine controls, unrelated to braking, over the years as well. But what all of these technologies have typically had in common is that they’ve existed as standalone, point-to-point functions that have not been integrated together. The present and future of braking is all about taking the next logical step--getting fully connected and finding ways to embed intelligence throughout a machine.

Electromagnetic Know-How
Finite Element Analysis (FEA) software can be used for a variety of mechanical engineering tasks, including injection molding simulation of plastic parts, analysis of aerospace components, impact and crash analysis of automobiles and the electromagnetic analysis of motors, actuators, transformers and sensors.

Sorting Out Flexible Couplings
In most cases, industrial power transmission calls for flexible rather than rigid couplings in order to forgive minor shaft misalignment. For that reason, this article will focus solely on the selection of flexible couplings.

A look at the IMTS 2012 show from a power transmission component perspective.

Technical Articles

Sleeve Bearings or Tilting Pad Bearings - Ask the Expert
A reader asks whether sleeve bearings can take the place of more expensive tilting pad bearings in a high-speed compressor application.

Wear-Resistant Bearings
More than a decade of intensive research and development has resulted in two new technologies that, when used in combination, expand the performance of rolling element bearings well beyond previous limits.

Bearing Protection Needed if Inverter-Duty Motors Are to Live up to their Name
All major manufacturers of 3-phase AC induction motors offer "inverter-duty" or "inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings--their most vulnerable parts--are too often ignored.

IANA and the Increasing Relevance of IMTS (Publishers Page)
Many of you probably think of IMTS as just a machine tool show. Of course, it’s hard not to. With the majority of the show focused on metalworking equipment, tooling and supplies, there’s no doubt that IMTS is a machine tool show. But this year, the show has partnered with Hannover Messe to include IANA—Industrial Automation North America.
