Outer Rotor Direct Drive Torque Motor with Hall Sensors and Incremental Encoder

Outer Rotor Direct Drive Torque Motor with Hall Sensors and Incremental Encoder

●  Introduction

TDB-170-095-NH-A Direct Drive Torque Motor adopts an outer rotor design, which structurally makes it easier to achieve higher moment of inertia and a larger output radius. It comes with Hall sensors for easier startup and better compatibility with a wide range of drives. Equipped with an incremental encoder, it is suitable for most servo control systems. With a positioning accuracy of ±20 arc seconds and repeatability of ±1.5 arc seconds, it meets the requirements of precision machining and inspection. It is widely used in applications such as CNC rotary tables, semiconductor equipment, robotic joints, and precision inspection.
