New STAC6 Stepper Drives offer sophisticated motion algorithms and increased levels of programmability. The drives offer current output up to 6A, direct ac input without a transformer, bus voltages up to 200V ac and software selectable resolutions from 200 to 51,200 steps/rev at speeds up to 133 rps. New DSP-based algorithms focus on anti-resonance technology, demand signal smoothing, torque ripple smoothing and microstep emulation for systems that require low step resolutions. Self-Test and Auto-Setup features measure and configure motor parameters automatically. Macro assembly language programming provides register manipulation, conditional processing, math functions, multi-tasking capabilities, plus pulse & direction and encoder following capabilities for electronic gearing.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
