DDRE-325-065 Direct Drive Rotary Motor
High Torque · Zero Backlash · Precision Control
Ⅰ. Product Overview
The DDRE-325-065 Direct Drive Rotary Motor from W-Robot is a large-diameter, high-precision rotary actuator engineered for applications demanding high torque, direct coupling, and extreme positioning accuracy. Utilizing advanced direct-drive (DD) motor technology, this model eliminates the need for mechanical reduction systems such as gears or belts—achieving zero backlash, high rigidity, and exceptionally smooth motion.
With a rotor diameter of 325 mm, the DDRE-325-065 provides remarkable torque density, superior load capacity, and outstanding speed stability, making it ideal for high-end robotic rotary joints, indexing tables, semiconductor wafer stages, and optical alignment systems.
Ⅱ. Technical Features
Direct-drive design: Ensures precise angular control and zero mechanical backlash.
High torque output: Optimized electromagnetic design supports powerful continuous and peak torque delivery.
Low cogging torque: Guarantees ultra-smooth motion, even at low speeds.
High-resolution feedback: Compatible with absolute and incremental encoders for sub-arcsecond accuracy.
Rigid and compact structure: Ideal for limited-space installations in advanced machinery.
Long service life: Frictionless design minimizes mechanical wear and maintenance.
Efficient heat dissipation: Optimized stator and housing design for stable performance under sustained load.
Ⅲ. Application Fields
The DDRE-325-065 model is designed for precision motion systems across multiple industries, including:
Semiconductor processing and inspection systems
High-precision rotary tables and indexing mechanisms
Robotic joints and collaborative robot axes
Optical measurement, alignment, and laser scanning platforms

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.
