The Energy-efficiency Quest Intensifies

The Energy-efficiency Quest Intensifies Unless your head has been buried in a long-term design project, you've seen demand rise sharply for more energy-efficient motion systems. What may have escaped notice is the shifting attention away from easier pickings — like specifying smaller and more efficient motors and drives — and toward energy evaluation of everything in the system. As engineers consider options like reducing friction, eliminating components, or re-examining duty cycles and peak torque issues, they may seek assistance crunching the numbers. This Design News article presents some of the less-explored paths to energy savings and some of the analytical tools that might help in the quest.

Averaging for Positional Accuracy

Averaging for Positional Accuracy When the task is steering laser beams for marking or cutting, only the highest accuracy will do. One way to improve precision in positioning rotary tables is to average multiple feedback signals. This new dual-axis encoder is designed for the task, and to handle speeds up to 1300 rpm.

Video: Programmable Encoder Elite

Video: Programmable Encoder Elite Not all programmable encoders are created equal. While all start with high native resolutions, it's the algorithm that differentiates good from unreliable, and prevents the duty cycle from deteriorating. In the devices showcased in this video, resolution is stored redundantly in non-volatile memory, making them as reliable as fixed-disc encoders.

Mini Metric When Size Matters

Mini Metric When Size Matters When loads are light and the job demands small size, close tolerance positioning, and high-speed, this 8x6 mm stainless ball screw stands alone in the market. It's specifically suited for medical applications, such as when rapid approach and retraction is required. Bonus: precision-rolling, instead of grinding, helps lower component cost.

Reducing Wobble in Rotary Work

Reducing Wobble in Rotary Work Getting tooling in exactly the right place when manufacturing semiconductors, fiber optics, and other precision products can be challenging. These compact stages — featuring low profile, anodized aluminum body, and pre-loaded ball bearings — are designed to rotate components or tooling within confined spaces, helping to deliver smooth rotation and minimum wobble.

It's All in the Timing

It's All in the Timing In so many situations — from product introductions to telling jokes — success depends heavily upon timing. To make sure the timing is just right in a motion system, this new microcontroller incorporates multifunction timer-pulse units and a 16-bit general-purpose PWM timer. This allows for simultaneous control of up to three 3-phase motors.

Controller Cuts Unplanned Downtime

Controller Cuts Unplanned Downtime When thousands of motors operate in an industrial facility, just keeping them going can keep everyone on edge. This "universal" device offers uncommon assistance — help minimizing unplanned outages. Diagnostic and control functions, including pole reversal, load-shedding restarts, thermal load monitoring, help prevent motor overloads and correct faults quickly should trips occur.

Manifesto Maps an Engineering Future

Manifesto Maps an Engineering Future Many nations face the challenge: how to maximize engineering's contribution to society. The dilemma inspired eight UK engineering organizations to publish a manifesto aimed at swaying pre-election opinion. Too often, it infers, public investing in engineering and turning it loose on society's biggest challenges gets talked about, but action isn't sustained. The call for action urges the political sphere to acknowledge engineering's role in fostering a stronger economic base.

Video: Solar Flight — On a Wing and a Prayer

Video: Solar Flight — On a Wing and a Prayer It was once thought impossible: a huge, lightweight emissions-free aircraft flying continuously through day and night using only energy collected from solar cells mounted on its wings. Yet, in April, the prototype Solar Impulse, weighing 1,600 kg despite its jaw-dropping 63 m wingspan, completed its inaugural flight over the Swiss countryside.
