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.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
