This system's NEMA17 high-torque, brushless motor design uses innovative techniques to control current flow through the motor, reducing resonance throughout the MDrive's speed range and making it quieter. It can take a broad input voltage range from +12 to +48 V dc. It runs at an extended operating range of -40 to 85C, and its general purpose I/O, running to +24 Volts, has been expanded from 4 to 8. The MDrive17 has a full-featured, easy-to-program instruction set, a 10-bit analog input, 0-5 MHz step clock rate, and 20 microstep resolutions up to 51,200 steps per revolution. Expanded features make electronic gearing possible with an output clock generated fixed to the internal step clock, or by following a rotary or linear axis at an electronically controlled ratio. Options and accessories include a long life linear actuator; encoders; integrated planetary generator; control knob and linear slide.
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.
