MagneTek's microsize GPD 205 adjustable frequency drives are now available in 460V ac models. The new models come in four incremental ratings from 0.5 to 3 hp. Although only a fraction of the size of conventional PWM drives, the GPD 205 is said to be useful for sophisticated equipment control in applications that include fans, pumps, mixers, agitators, compressors, conveyors, commercial laundry, and material-handling installations. The drive's 16-bit microprocessor provides the flexibility, features, and performance for a wide range of operational requirements. It installs and programs easily, has the versatility to adapt to simple or complex applications, and is UL-listed, CSA-approved, and CE-marked. MagneTek Drives & Systems. Product Code 4361
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
