P3™: New Patent / New Product

The Puck®—weighing only 4 grams

Barrett wins Puck® Patent #10,148,155.

This is the 4th patent supporting the Puck®, so named for its resemblance to a hockey puck. The 3rd-generation Puck®, aka P3™, is an amazing accomplishment. At only 4 grams (1/6X smaller than the nearest competitive brushless-servomotor drive), P3™ represents a game-changer for OEMs who need an extremely compact and networked servomotor-controller+encoder with vastly simplified wiring. 

Barrett collaborated with Draper’s internationally-renowned engineers and resources to subject P3™ to extremes of temperature, vacuum, and vibration under NASA contract #NNX17CP20C. This tough little CANbus-networked device, the diameter of a penny and less than 5 pennies thick, contains a 12-bit absolute encoder, 32-bit processor, and power electronics, adding less length to the motor than a typical encoder alone.

According to Barrett CEO, Bill Townsend, "We've actually been in the motor-controller business for 20 years, developing the Puck®. But the Puck® has been mostly hidden from view as we've been its chief OEM customer until recently. Now we want to share this technology with others as a way to make the biggest impact." In 2017, Barrett quietly began selling its new P3™ to OEM customers and has so far sold more than 1,000 P3s in commercial applications (medical, aerospace, entertainment) all working hard under various operating environments across several continents.
