The Linearserv direct-drive linear brushless servo does not feature rotary-to-linear conversion devices or any other components that can introduce inaccuracies and system complexities. The Dynaserv direct-drive brushless servo provides high accuracy and torque without speed reducers, offering fast setting times and smooth rotation at slow speeds. Brochure includes information on these two models as well as the DM 1004 Series Dynaserv motor/drive system. Also included are dimensional drawings, product photography, performance curves, and ordering information.

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?
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.
