Maxon Precision Motors' new "RE" series of motors use powerful rare-earth magnets and graphite brushes to eke out the highest torque possible in a 25-mm diameter package, Maxon says. As with the company's other motors of this design, the RE series uses a patented rhombic moving coil design to deliver long life, low electrical noise, fast acceleration, and high efficiency. The ironless rotor allows for zero cogging and simple, accurate control. Weighing 4.6 oz and measuring 2.1 inches long, the 25 mm motor is rated at 20W. Maximum speed is 11,000 rpm, and maximum efficiency is 87%. Maxon Precision Motors, Product Code 4216.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
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.
