The hollow-core design of the IOS (Inside Out Stepper) motor reverses the conventional stator and rotor positions. Result: a large-through-hole configuration. The laminated stator assembly fits onto a non-rotating pedestal surrounded by a rotatable shaft cup assembly with an open shaft face.
A mirror or filter wheel, mounted in close geometry on the hollow-shaft face, rotates to various positions and angles for light-beam refraction.
The stationary through-hole accommodates a wide range of optical, electrical, pneumatic, hydraulic, and mechanical components without the potential of chaffing. A simple but effective way to increase motor torque performance without expensive internal changes is to lengthen the IOS motor by stacking motors together.
The size 17-rotor assembly is composed of a permanent-magnet ring surrounded by two soft-iron cups. These cups are laminated and comprised of 50 small vernier teeth. The second rotor cup assembly is constructed similarly, but with a one-half tooth pitch orientation to maximize rotor torque. The miniature size 17 IOS rotor uses a rare earth (Samarium-Cobalt) magnet while the larger size 23 and 34 rotors use alnico.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
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.
