NO SPACE? NO PROBLEM
Barrett’s latest advancement comes in the form of two high-performance Puck® P4’s: both a 16mm and 37mm version. With patented dual iSense control and onboard magnetic encoder, motor control has never been so sophisticated, yet so simple. This revolutionary design features snap-on connectors and daisy chain wiring for quick and easy integration with any low space, high-performance application.
The P4-16™ is designed to fit seamlessly in any situation. At just 1.2 cubic cm, 2 grams, and up to 1/4KW drive power, this motor controller elegantly balances power and size. While this motor controller runs complex space-vector commutation and constant high speed computations, implementation is about as simple as it gets.
While the P4-16™ masters the art of size and strength, the P4-37™ is designed to push the boundaries of motor control without all the bulky electronics. At a modest 12.5 cubic cm, 16 grams, and 1.75KW peak drive power, this small motor controller is built for big output. With up to 160V input, and over 10A peak output, the P4 - 37™ drives motors at both higher speeds and higher torques. This design fits perfectly in high-speed and high-payload applications, like Barrett’s own Ultra-High-Speed WAM 3.0.

Competitor Comparisons
Small but Mighty
The Puck improves performance, efficiency, and accuracy (while reducing volume 10x!)
The Puck® P4-16™ combines power and elegance with its compact design and sophisticated motor control. Its Daisy Chain topology reduces wiring and enables a network of up 31 Pucks® per bus. With on-board encoder, the P4-16™ eliminates signal degradation, power loss, and cable bulk inherent to standard motor-control.
At just 6mm tall, the P4-16™ fits snugly against the back of any motor. Just snap the Puck into place, and let decades of Barrett engineering handle the rest.
With 250W of power, heat can be a challenge. With built in heatsink and an operating range of -25°C to 100°C, the P4-16™ offers near silent, fan-less performance without compromising speed or payload.
Please contact Barrett's experts at sales@barrett.com to see if the Puck® P4-16™ is a good solution for your OEM application.
Compact, Competitive
With a diameter of 16mm, the P4-16 Puck is 2-3x smaller when viewed from the top.
