​Revolutionizing Precision Transmission and Driving the Upgrade of High-End Manufacturing

In the field of advanced equipment manufacturing, Direct Drive (DD) motors, also known as torque motors or direct-drive motors, are becoming a revolutionary technological engine. Thanks to their high precision, high rigidity, excellent dynamic response, low vibration, compact structure, and zero intermediate transmission mechanism, DD motors are widely adopted in industrial applications where rotational accuracy, response speed, and transmission efficiency are extremely demanding.

Smartwin offers a diverse and comprehensive product portfolio, including:

• DBM Series – Frameless torque motors

• DH Series – Modular torque motors

• DDA / DDR Series – Hollow-shaft outer-rotor and inner-rotor torque motors

This complete series enables Smartwin to support a wide range of applications, providing customers with one-stop high-precision transmission solutions.

Unmatched Performance in Semiconductor Manufacturing

In semiconductor production, requirements for precision and stability are exceptionally strict. Micron-level positioning accuracy, zero-backlash transmission, and compatibility with vacuum environments are essential.

For example, in IC test handlers and wafer dicing machines, Smartwin DD motors offer:

• High rigidity, ensuring strong resistance to external disturbances

• High-speed start/stop with millisecond-level response

These capabilities ensure that wafers maintain stable, wobble-free rotation during high-speed positioning, fully meeting the precision needed for micron-level inspection and processing.

Superior Integration for LCD Manufacturing and Display Equipment

In the LCD and flat-panel display industry, compactness, high integration, and low vibration are crucial.

For instance, in film-lamination machines, the hollow-shaft design of Smartwin’s DD motors allows power and signal cables to pass directly through the center, significantly saving interior space and supporting high-density machine integration.

In color filter coating equipment, Smartwin DD motors provide:

• Zero-backlash transmission, eliminating mechanical play

• Highly uniform coating motion, reducing defects and improving yield

High-Speed Dynamic Response in Industrial Automation & Robotics

In industrial robotics and automation, core requirements include:

• High dynamic response

• Flexible load matching

• Compact structure

For robot joint drives—such as collaborative robots and articulated arms—Smartwin DD motors provide:

• 30% increase in system rigidity through direct load coupling

• Superior accuracy and stiffness, ideal for precision joints

In fast-paced automation systems such as assembly lines or inspection equipment (e.g., welding machines), DD motors achieve:

• Millisecond-level acceleration/deceleration

• As fast as 2 ms settling time, far outperforming traditional servo motors

This dramatically enhances manufacturing throughput and precision.

Key Advantages of Smartwin DD Motors (Torque Motors)

Smartwin DD motors offer:

• Convenient hollow shaft

• Zero gear wear, maintenance-free operation

• Compact size

• High-stiffness cross-roller bearings

• Zero-backlash direct drive

Most importantly, because the rotor is directly coupled to the load, all errors caused by intermediate transmission mechanisms are eliminated, achieving the highest level of motion control precision.

Advantages Over Conventional Motors

• Precision: Within ±2.5 arcseconds

• Response Speed: No mechanical conversion mechanism, extremely fast response

• Angle Division: Any division possible; freely configurable

• Structure: Direct drive, no additional transmission components

• Installation: Simple structure, easy to mount

• Energy Efficiency: Higher efficiency through direct-drive power transfer

• Maintenance: Fewer components, low friction, easy to maintain

A New Benchmark for High-End Precision Transmission

Smartwin DD motors have become a symbol of high precision, high efficiency, and high compactness in the high-end manufacturing sector. Their robust mechanical design and superior performance continue to drive advancements in industrial automation towards higher precision and intelligence.

This technology not only boosts production efficiency but also strengthens the competitiveness of domestic high-end equipment in precision manufacturing. Smartwin DD motors are rapidly becoming a key driving force behind industry upgrade and technological innovation.
