Hollow Shaft Servo Motor features a through‑bore design at rotor center. Developed for high‑end precision automation, it allows cables, air tubes, optical fibers and drive shafts to pass directly through the rotor, eliminating external cable chains and slip‑rings and greatly simplifying machine layout. It is widely applied in collaborative robot joints, semiconductor wafer platforms, optical rotary stages, medical automation equipment, precision inspection instruments and 3C automation rotary stations. Equipped with high‑resolution closed‑loop encoder and optimized permanent‑magnetic magnetic circuit, this series Hollow Shaft Servo Motor delivers large bore size, high torque and superior positioning accuracy. With high system integration, compact dimension and fast dynamic response, it acts as a key power component for overseas B‑end system integrators to realize equipment miniaturization and rotary‑unit integrated design. Customization on bore size, flange and torque is available together with one‑stop supply of matched servo drivers.
Central Hollow Through‑bore Structure
This Hollow Shaft Servo Motor comes with penetrating rotor hollow bore. Cables, air pipes, optical paths and drive shafts can run straight through motor axis without extra external wiring assemblies. It avoids cable bending‑interference risks and greatly simplifies mechanical layout for rotary mechanisms, ideal for precision stations with 360‑degree endless rotation.
High‑rigidity Closed‑loop Positioning Control
The hollow shaft servo motor is fitted with high‑precision absolute encoder for stable closed‑loop feedback and excellent repeat positioning accuracy. Reinforced bearing structure provides strong tilting‑moment resistance. It runs smoothly without jitter under frequent high‑speed direction reversal, meeting strict positioning requirements of optical and semiconductor equipment.
High Torque Density Flat Housing
The newly upgraded Hollow Shaft Servo Motor adopts optimized magnetic circuit and rotor mechanical design to guarantee torque output with hollow bore. Its flat compact housing offers multiple flange options to save inner installation space. Compatible with mainstream motion buses, it connects with PLC and motion controllers and meets global industrial equipment standards.
Simplified System Integration
The hollow through‑bore design reduces the adoption of cable chains, slip‑rings and external adapters and cuts total component count to shorten machine development cycle. Hollow Shaft Servo Motor helps overseas equipment manufacturers shrink overall machine dimension and improve reliability of rotary units.
Low‑maintenance & High Operational Stability
Removing external wiring assemblies lowers failure risks caused by cable wear and breakage. Optimized bearings and permanent‑magnetic windings enable long‑time high‑frequency reciprocating rotation, reduce machine downtime and effectively cut later‑stage maintenance and component replacement costs.
Multi‑specification & Flexible Retrofit Compatibility
This series hollow shaft servo motor supplies multiple options for hollow bore diameter, flange size, voltage and communication protocols with standardized mounting interfaces. It supports mainstream industrial buses including EtherCAT and CANopen for easy embedding into existing rotary stations and fast commissioning for overseas factories.
