Lin Engineering's new 4518 NEMA 17 stepper motors are designed exclusively with the company's patent-pending Signature Series technology and are the new and improved version of Lin's 4118 motors. The 4518 series is available in three different stack lengths starting with the 4518S at 1.34 inch in thickness and the 4518L measuring in at 1.89 inch. Depending on the stack length, these motors are capable of producing up to 83 oz-inch of holding torque. The new series is suggested for use in applications where size is a factor and load capacities are critical to precision system operation. Industries currently benefiting from the features of this motor in their applications are medical, printing, imaging, optical and robotics. Lin's Signature Series was developed to help reduce system resonance and provide overall smooth motion. Depending on the application, using motors with the Signature Series technology may result in up to 50 percent less resonance being produced.
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?
