Maxon Motor USA continues to shrink the size of its integrated motors and feedback devices. Here at the Medical Design and Manufacturing Show West in Anaheim, CA, the company showed off a new 6-mm DC motor with an integrated magnetoresistance (MR) encoder. “It's part of our growing focus on miniature mechatronic systems,” says Kirk Barker, the company's electronics product manager. Previously, the smallest size integrated motor of this type was 10-mm, Barker says. One of the first uses for the new motor is in a precision medical pump. Barker explains that the motor not only helps operate the pump but also acts as a sensor that reveals blockages or malfunctions—which turn up as changes in back-EMF and current. Stay tuned for more technical details on the new motor-encoder package as they become available.
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
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 radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
