Direct Drive Servo Motor eliminates intermediate transmission components such as gears and couplings to drive loads directly. With zero backlash, low‑speed high‑torque and high repeat positioning accuracy, this Direct Drive Servo Motor is widely used for precision rotary tables, semiconductor equipment, automation machinery and robots. It simplifies mechanical design, lowers maintenance and improves machine positioning accuracy & running stability.
Zero‑Backlash Direct‑Drive Structure
This Direct Drive Servo Motor works without gearboxes or belt transmission. The motor drives load directly to eliminate transmission backlash completely. Compared with conventional servo systems, it avoids accuracy drift caused by gear wear and guarantees stable positioning for precision machines over long‑time operation.
Low‑Speed High‑Torque Performance
The Direct Drive Servo Motor delivers continuous high torque at low rotating speed without torque amplification from reduction gears. It performs smooth heavy‑load operation for rotary index tables with minimal speed fluctuation.
Built‑in High‑Resolution Absolute Encoder
Equipped with high‑resolution absolute encoder, this Direct Drive Servo Motor provides million‑level pulse feedback for sensitive closed‑loop control. It achieves arc‑second level angular positioning for demanding automated production processes.
Excellent Overload Capacity for Shock Load Resistance
This Direct Drive Servo Motor features great short‑time overload capacity and tolerates instant shock loads. It runs stably under frequent start‑stop and sudden impact conditions, protecting the whole motion system and adapting to variable load requirements of automation production lines.
Optional Hollow Shaft for Convenient Cable & Pipeline Routing
Direct Drive Servo Motor is available with hollow shaft design. Cables and air tubes can pass through the motor central bore directly. It keeps wiring neat, avoids cable tangling and optimizes mechanical layout for precision rotary tables and optical equipment.
High Repeat Positioning Accuracy for Consistent Production Quality
Benefiting from backlash‑free direct drive transmission, Direct Drive Servo Motor delivers superior repeat positioning accuracy with tiny angular deviation for each rotation. It ensures uniform precision for mass‑produced workpieces, reduces defect rate and improves overall production quality of machinery.

Q: Will positioning accuracy degrade after long‑term 24‑hour continuous operation of your Direct Drive Servo Motor?
A: Our Direct Drive Servo Motor has no wearing gear parts, so there is no accuracy degradation caused by mechanical wear. After long‑time aging test, it maintains original positioning accuracy under 24‑hour continuous running. Accuracy shift is mainly caused by ambient temperature; proper heat dissipation keeps stable performance.
Q: Will large eccentric load shorten the service life of Direct Drive Servo Motor?
A: Eccentric load beyond allowable radial load will reduce bearing service life. The bearings of our Direct Drive Servo Motor are reinforced to withstand certain eccentric load. Please send us your eccentric data during selection, we will check your working condition to prevent premature bearing failure.
Q: How much modification work is needed to replace traditional servo motor with your Direct Drive Servo Motor on existing machine?
A: Modification effort depends on flange dimension, mounting size and driver protocol. Our Direct Drive Servo Motor supports customized flange size and multi‑protocol encoder. In many cases, only motor replacement and minor parameter adjustment are required, without large‑scale mechanical rework.
Q: Do high‑torque models of Direct Drive Servo Motor require extra water‑cooling due to heavy heat generation?
A: Standard Direct Drive Servo Motor models work well with natural air cooling for most applications. Water‑cooling structure is optional for heavy‑duty continuous‑load scenarios to control temperature rise and ensure full‑load long‑time operation of the Direct Drive Servo Motor.
Q: Can Direct Drive Servo Motor handle frequent high‑speed forward‑reverse reciprocating motion?
A: Yes. Featuring high stiffness and zero backlash, this Direct Drive Servo Motor is well‑suited for frequent forward‑reverse cycles. However, high‑frequency reciprocating movement accumulates heat. Please provide cycle time and torque duty data, we will verify your condition to avoid over‑specification usage.
