To improve motor performance and lower manufacturing costs, rotor-embedded flat NdFeB magnets replace surface-mounted curved magnets. The design effectively doubles the magnet's power volume providing flux for higher torque to inertia, and reduced size and weight.
Stainless-steel center shaft, non-magnetic-retainer rings and glass-fiber rods prestress the rotor assembly. The prestressed rotor cage delivers torque allowing center-shaft elimination in small-diameter motors. High mechanical stiffness allows increased current-loop gains.
The design secures magnets even at high speeds, eliminating the need for special rotor banding. Schlenker Enterprises has designed the synchronous ac servo motor in four diameters rated from 1 Nm to 147 Nm.

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.
