FLUID POWER: ThinGap LLC announced a TG14090 Brushless dc Ring Motor that delivers 122 kW of shaft power, allowing a ducted-fan to generate 600 pounds of thrust, depending on the fan blade design. The motor provides an exceptional power to weight ratio—6.4hp per pound; a compact package that fits the control inside the motor and low thermal load characteristics.
The TG14090 design provides a low profile platform that is quiet, cool running, and saves power. By utilizing a cantilever fan blade design, the hub can be designed for either open or closed operation. An open hub provides additional surface area that increases cooling, allowing higher input voltage and shaft output power. A closed hub design fits the control can within the hollow space of the motor for a compact and more aerodynamic package.
Based on physical tests, the operating characteristics of four design configurations for the TG14090 have been calculated. The projections indicated that 70 to 122 kW of continuous shaft output power is possible. This allows a TG14090 configuration, weighing 25.6 lbs. and producing shaft output of 163hp, to deliver 6.4hp per pound of motor weight.
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.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
