This compact unit includes a bipolar, 1.8-degree NEMA 17 step motor, along with an integrated microstepping driver and intelligent controller. Its affordable design needs no outside equipment. RoHS-compliant versions are available upon request. It comes in 2.76, 2.99 and 3.31-inch lengths and puts out up to 85 o-inches of holding torque, depending on motor stack size, with custom windings available for free. It has output currents of 0.1 to 1.5 amps peak, input voltage of 7V dc to 28V dc, and 16 kbytes of onboard memory. It has a general-purpose input switch for manual motor positioning and an open collector output switch that can put out 100 mA. It can be programmed for stand-alone operation with no PC, and has low enough power dissipation that it needs no heat sink. Its StallGuard™ stall detection feature means no encoders are needed.
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.
