This all-digital drive combines four motor control technologies into a single drive package: high-performance ac flux vector drive, high-horsepower servo drive and programmable motion controller and PLC technologies. Unique drive architecture enables the unit to control ac induction, ac synchronous, or brushless dc motors in the power range from 1 to 350 hp. All models provide extensive analog and digital I/O, feedback, serial communication capabilities, and dynamic braking control. Digital signal processor (DSP) technology implements the advanced space vector and motion control techniques and insulated gate bipolar transistor (IGBT) power devices directly control the motor. The unit supports encoders or resolvers, as well as operation, without a transducer for less-demanding, velocity-loop applications. Communications options include two fully-isolated RS-422/485 serial interfaces for connecting the drive to a process controller, communication network, or programmable controller, and an RS-232 port for connecting to a PC.
Boeing continues to tweak the design of its 737 Max to add fuel efficiency to the next-generation jetliner with a change in the size of fan on the plane’s CFM LEAP-1B engine.
With its QuickPack print engine technology, easy-to-use preprocessing software, and hands-free cleaning system, Stratasys' Mojo is taking professional-grade 3D printing to a new level.
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.
