Ultra-Small Pancake-style Gimbal Motors Developed by Orbex

Servo motors are at the heart of modern gimbals, allowing them to move and position components in tracking and communication equipment for military and surveillance devices, navigation systems, industrial robots as well as drones and UAVs. In order to achieve the precision these demanding applications require, the motor must operate smoothly and offer high torque and low cogging capabilites. Being compact and lightweight for use in space-constrained and mass-constrained devices can also be key attributes. 

To meet these challenges, Orbex Group has introduced a line of ultra-compact high-performance gimbal motors. Featuring a pancake-style form factor and with Neodymium permanent magnets inside, the motors are wound to operate at low speeds typical for gimbals while exhibiting a high torque constant for fast response when needed. 

They are engineered to minimize cogging torque and ensure smooth rotation for stable imaging or pointing. Because these brushless motors are electronically commutated, they can change speeds quickly and offer exceptional reliability. They are also lightweight, an important characteristic for drones, UAVs and other airborne craft that need to maximize flight time. 

There are two standard sizes: 16 millimeters (OD) by 10 millimeters (H) and 26 millimeters (OD) by 12 millimeters (H). In addition, Orbex can also engineer them to custom applications with special windings, connector configurations or mounting interfaces, and a magnetic encoder can easily be integrated for feedback. 

Based in Austin, Texas, Orbex produces slip rings and electric motors for a range of OEM applications. Its motor portfolio includes DC-coreless electric motors, brushless electric motors and electric servo motors. For more information, visit www.orbexgroup.com.
