DDRE-140-80 Direct Drive Rotary Motor
High Torque · Large Hollow Shaft · Precision Rotation Without Backlash
Ⅰ. Product Overview
The DDRE-140-80 from W-Robot is a high-torque, large-aperture direct drive rotary motor developed for advanced automation and robotics applications requiring exceptional precision, rigidity, and responsiveness.
With a 140 mm outer diameter and an 80 mm large hollow shaft, this model offers superior torque density while maintaining a compact, integrated structure. The direct-drive mechanism eliminates mechanical transmission elements such as belts or gears, providing zero-backlash motion, high repeatability, and ultra-smooth rotation.
Its open-center hollow design allows for convenient cable routing, vision sensors, or pneumatic lines, making it ideal for robotic joints, rotary platforms, and semiconductor handling systems that demand compact and high-precision rotary actuation.
Ⅱ. Technical Features
Direct Drive System: Ensures zero backlash, high stiffness, and instant torque response.
Large Hollow Shaft (Ø80 mm): Allows internal routing of cables, air pipes, or optical paths.
High Torque Output: Optimized magnetic circuit delivers powerful torque within a compact size.
Smooth & Silent Motion: Low cogging torque and precision bearing design ensure minimal vibration.
Compact Design: 140 mm frame diameter suitable for integration into limited-space systems.
High-Resolution Encoder Support: Enables sub-arcsecond positioning accuracy.
Maintenance-Free Operation: No belts, gears, or lubrication required — ideal for clean environments.
Ⅲ. Application Fields
The DDRE-140-80 is designed for precision rotary motion control in high-end industrial systems, including:
Collaborative robot and manipulator joints
Wafer handling and inspection equipment
Rotary indexing or turntable systems
Optical and laser processing equipment
Medical and life science automation
Precision assembly and testing platforms
Its high dynamic response and compact integration capabilities make it a preferred choice for OEMs developing space-efficient and high-performance automation systems.
Ⅳ. Model Selection & Customization
W-Robot offers flexible customization for the DDRE series to meet diverse application demands:
Encoder options: absolute / incremental / serial type
Shaft configuration and mounting flange customization
Torque and speed tuning for target load dynamics
Cooling options: natural / forced air / liquid cooling
Integrated servo drive for compact embedded control
Multi-axis solutions (rotary + linear motion systems)
Ⅴ. Product Advantages
Zero mechanical backlash, high rigidity, and precision control
Large 80 mm hollow shaft for simplified cable and tube management
High torque density with efficient electromagnetic design
Quiet, smooth operation — ideal for sensitive environments
Compact footprint supports dense machine layouts
Long service life with minimal maintenance requirement
Ⅵ. Installation & Maintenance
Mount on a stable, vibration-free base for accurate alignment.
Tighten all fasteners with specified torque values.
Keep the shaft hole and mounting surface clean and free of particles.
Avoid prolonged exposure to moisture, dust, or magnetic interference.
Periodically inspect encoder calibration and torque output stability.
Ensure proper electrical grounding during integration.

FAQ

Listed below are answers to our most commonly asked questions. Don't see your question?Contact our customer service team. We would be glad to assist you.

What are the future development trends of linear modules and linear motors?

In the future, linear modules and linear motors will develop towards higher precision, higher speed, smaller size, intelligence, and integration with other advanced technologies (such as artificial intelligence and the Internet of Things).

What parameters need to be provided for customized linear motors?

It is necessary to provide detailed parameters such as load weight, stroke, speed, acceleration, accuracy requirements, installation method, and operating environment so that the manufacturer can design and manufacture a linear motor that meets the requirements.

How long is the customization cycle of linear modules?

The customization cycle depends on the complexity of the customization and the manufacturer's production capacity, generally about 1-4 weeks. The specific time can be determined by communicating with the manufacturer.

Can linear motors be upgraded?

The performance of linear motors can be improved by upgrading them with high-performance drives, optimizing control system parameters, and improving heat dissipation structures.

Is it easy to upgrade the linear module?

It is relatively easy to upgrade the motor, control system, guide rail and other components of the linear module according to actual needs to improve its performance and accuracy.

What is the after-sales maintenance service of linear motors?

Regular manufacturers usually provide comprehensive after-sales maintenance services, including fault diagnosis, maintenance guidance, parts replacement, etc., but the response speed and quality of after-sales maintenance services may vary from manufacturer to manufacturer.

What is the warranty period for linear modules?

The warranty period of linear modules from different manufacturers varies, generally around 1-2 years. The specific warranty period can be confirmed with the manufacturer at the time of purchase.

What should we pay attention to when integrating linear motors with other equipment?

Attention should be paid to issues such as interface compatibility, signal matching, control logic coordination, and installation space and layout between devices to ensure that the devices can work together.

Can the linear module be integrated with other equipment?

Absolutely. Linear modules can be integrated with other devices such as robots, sensors, and vision systems to build more complex and intelligent automated production lines.

What kind of control system do linear motors require?

Linear motors typically require a high-performance motion control system that can achieve precise position control, speed control, and thrust control, such as a dedicated linear motor drive with a motion control card or a high-end PLC.
