A new brushless dc motor from MicroMo Electronics Inc. has an external motor-diameter of only 20 mm and a length of 57 mm. It provides high power-to-volume ratio by using a skewed winding in combination with a rotor made of Neodymium rare-earth magnets to provide cog-free motion. The brushless dc motor can achieve a continuous output torque up to 18 mNm at speeds up to 58,000 rpm. The motors come in a sterilizable version capable of withstanding an autoclave environment. The Series 2057 can be combined with a gearbox and encoder for a miniature dc drive system.
The Department of Defense and the Office of Naval Research are funding the design of Web applications that will help protect and police coastal waters.
This year, when Indy teams search for a competitive edge on the track, they're going to have to dig deeper into the mechanical aspects of the car than ever before in the history of the race.
A new process for laser-welding large-scale, steel-aluminum foam sandwich structures for lightweighting ships, which eliminates intermetallic phase, has been demonstrated.
The Department of Defense is designing a device that can virtually cure sepsis, an often fatal blood infection to which soldiers injured on the battlefield are prone.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
