A 5-MW motor using HTS (high-temperature-superconducting) wire and magnets has passed load- and ship-mission-testing protocols. American Superconductor designed the motor under an Office of Naval Research contract as an interim step toward a 36-MW, 49,000-hp, 120-rpm unit under development for ship propulsion. The goal is a propulsion system that has one-third the weight and one-half the size of conventional copper-based motors of the same rating.
The 5-MW motor underwent static and dynamic tests at the Center for Advanced Power Systems at Florida State University (Tallahassee). Alstom Power Conversion's (www.powerconv.alstom.com) Rugby, UK, facility designed, built, and conducted further tests on the stator- and marine-drive electronics. In the static tests, the motor ran at full load and speed, 230 rpm, for 21 hours; resultant temperature and performance data agreed with design predictions. In the dynamic test, the test station imposed load variations of 0.5 to 10 percent around moderate- and full-power operating points. Testing also used hardware-in-the-loop simulation to control the motor and emulate complete propulsion-system operation.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
