Compumotor has developed a direct drive rotary servo system that's the most compact in the company's Dynaserv line. Each consists of a brushless servo motor with 10-ft of motor and encoder cables, microprocessor-based drive, power supply, and an incremental encoder. Offered in both 4-inch and 6-inch diameter versions, they are available in speeds up to 2.5 rps and resolutions up to 655,360 positions per revolution. Axial and radial runout measures 10 mm--10 times better than the Dynaserv DR and DM series--with 5 mm available. Applications include scanning, semiconductor processing, disk drive assembly, rotary indexing, industrial robots, and low-speed inspection. Parker Hannifin, Compumotor Division, Product Code 4173.
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.
