January 26, 2010

The start of a new decade, and efficiency is still the #1 catch phrase when it comes to motor operation. No one questions the demand for efficient motors in industry. But did you know that in the 1970's, the average house had over 40 electric motors? That number has no doubt risen since then. Most energy consumption in the home occurs in the kitchen, with over half of that used by the refrigerator. It's small wonder energy efficient motors developed for industry are now migrating to the urban environment, as outlined in "Motor Control Turns to the Home."

You can help track the migration on MACHINE DESIGN's Blogs, LinkedIn, Twitter, and Facebook accounts, or visit the virtual MD Office in Second Life.

Motor Control Turns to the Home

High-efficiency motor drives used to be items only found in factories. Led by strong impetus from the Energy Star program (which now includes a new “Super Star” category), energy-efficient motors and drives are turning up in the high-volume consumer market.

Implants Keep the Blood Flowing

Engineers have developed a host of devices that keep a patient’s heart pumping and blood flowing.
One device approved for use during heart surgeries lasting up to six hours is the Implella 2.5 from Abiomed Inc., Danvers, Mass. Although only four inches long and 0.12-inches wide, it can pump 2.5 l/min. An encapsulated motor located in the part of the Impella outside the left atrium spins a microaxial pump at up to 51,000 rpm, pulling blood through the heart and dumping it in the left ascending aorta.

Top 10 Tips for Working with Gearmotors

Gearmotors are onerous components to select and incorporate properly. Here are 10 suggestions for maximizing gearmotor efficiency and service factors. Our panel of industry experts shows you how to make the most of these workhorses in your design.

Small Motor Market Faces an Uphill Battle

According to new statistics from IMS Research, Austin, the 2009 economic downturn has cut more than $700 million from the small motor market, which had peaked in 2008 at an estimated $3.018 billion. IMS forecasts that it will take until 2012 to return to these levels and that the market for some motor types, such as brushed dc motors, may never return to previous peaks.

Video: eCorner wheel integrates drive train, steering, shocks, and brakes

Siemens VDO engineers are working on plans to integrate the drivetrain, steering, shock absorbers and brakes directly into the wheels of future cars. This concept, called eCorner, is the basis for the ecological "Drive-by-Wire" automobiles, which may become a common sight on roads in 15 years. Length: 3:07
