Industrial Servo Drives Direct Drive DD Torque Motor with Hall Sensor

Industrial Servo Drives Direct Drive DD Torque Motor with Hall Sensor

●  Introduction

TDB-170-125-NH-B direct drive DD torque motor, with its outstanding structural design and stable control performance, is widely used in CNC rotary tables, semiconductor equipment, robotic joints, precision inspection, and other fields. This model adopts an outer rotor structure (all TDB series feature outer rotor design), which structurally makes it easier to achieve higher moment of inertia and a larger output radius, making it suitable for high dynamic response and high-load applications. It is designed for drive solutions that do not require Hall sensors for startup and is well compatible with most industrial servo drives, facilitating easy commissioning and deployment.
