A family of electrically released brakes are designed to automatically engage when power to them is disconnected.
The ERS spring set brakes use a system of springs and a magnetic coil to generate braking torque. This style is normally limited to use in static holding applications with only occasional emergency stop cycling. Five models handle torque ratings from 1.5 lb-ft to 100 lb-ft.
The FB/ER series permanent magnet style brakes use both a permanent magnet and magnetic coil to generate torque and control the brake. The magnetic coils counter permanent magnetic force to hold brake "off" when current is applied. All FB/ER brakes are designed for dynamic engagement applications which cycle brakes periodically. FB models, which include bearing mounting hubs, are available in three sizes and handle torque ratings from 10.5 lb-ft to 56 lb-ft. Seven ER models, which require assembly on the shaft, handle torque ratings of 10.5 lb-ft to 400 lb-ft.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
