The Direct-Drive Series

The BR series has a pancake high pole count stator design resulting in increased torque per weight and size. This is our most compact range of synchronous servo motors. The motor series comes in 4 frame sizes ranging from 70 mm to 180 mm. These motors are considered medium inertia making them a good fit for direct drive applications. These motors can be customized to fit your needs. Feedback options are nonproprietary, allowing these motors to be used with most third-party servo drives.
