High Torque Speed Precision Encoder Direct Drive Motor

●  Introduction

The TDB-112-065-NH-A direct-drive motor is structurally composed of four main parts: the stator (stationary part), the rotor (rotating part), the bearings, and the encoder (a sensor used to detect rotational position). The motor has a diameter of 112 mm, a height of 65 mm, and a weight of 2.8 kg. It delivers a continuous torque of 3 N·m and a peak torque of up to 9 N·m, with a rated power of 110 W, a continuous current of 2.5 Arms, and a peak current of 7.5 Arms. Its key features include high dynamic performance, high precision, optimal speed control, ultra-compact structure, excellent MTBF, and reduced maintenance requirements.
