Direct Drive DD Torque Motor
A DD motor (Direct Drive Motor) is also referred to as a direct-drive motor, torque motor, or hub motor. It is a specialized type of motor that transmits torque directly to the load, bypassing the need for intermediate mechanical transmission mechanisms (such as gears, belts, etc.). This design serves to minimize mechanical losses while enhancing both efficiency and precision
By connecting directly to the customer's load, the torque motor eliminates the need for intermediate coupling mechanisms—such as reducers or gearboxes—resulting in a highly compact overall assembly. It features stable and reliable operation, as well as low noise levels. Furthermore, the motor is equipped with a high-resolution rotary encoder, rendering the overall product structure even more compact while ensuring superior precision..
Linear Direct Drive Motor
With the rapid development of industrial automation and smart manufacturing, precision measurement technology has become essential for improving product quality and manufacturing efficiency. Advanced measurement equipment, including coordinate measuring machines (CMMs), optical inspection systems, and surface profilometers, is widely used in industries such as semiconductor manufacturing, automotive production, aerospace, and precision machining. These applications require motion systems with higher accuracy, repeatability, dynamic response, and long-term stability.
As a critical motion component, linear motor modules provide significant advantages through direct-drive technology, including zero backlash, high-speed response, micron-level positioning accuracy, low vibration, and stable operation over long travel distances. Compared with traditional transmission methods such as ball screws and belts, linear motor modules eliminate mechanical wear and transmission errors, delivering higher precision and efficiency for advanced measurement applications. Today, they have become a key solution for next-generation precision inspection and measurement equipment.

Yes. HONPINE provides customized solutions for mounting dimensions, hollow shaft diameters, encoder types, holding brakes, cooling methods, protection ratings, and electrical interfaces. Our engineering team works closely with customers to optimize motor performance for specific machine designs and operating conditions.
HONPINE Direct Drive Motors are widely used in semiconductor manufacturing, precision CNC machines, optical inspection equipment, lithium battery production, photovoltaic automation, medical devices, aerospace systems, robotics, and high-speed industrial automation where zero backlash and high positioning accuracy are essential.
Selecting the right Direct Drive Motor requires evaluating continuous torque, peak torque, maximum speed, load inertia, encoder resolution, positioning accuracy, hollow shaft size, and installation space. Providing your application details allows HONPINE engineers to recommend the most suitable motor and optimize system performance.
Linear modules can be installed in three main ways: horizontal, inverted, and side-mounted. In addition, if a load-balancing device is installed, the linear module can also be mounted vertically.
The choice depends on your performance requirements. Direct Drive Motors provide zero backlash, exceptional stiffness, and ultra-high positioning accuracy for precision rotary motion. Harmonic Drive Actuators deliver much higher torque density in a compact package, making them ideal for robotic joints and motion systems that require high reduction ratios. HONPINE offers both technologies and can help determine the best solution for your application.
DD motors can also be installed in three main ways: horizontal, inverted, and side-mounted.
For side-mounted installation, it is important to consider whether the load distribution is uniform. When the load moves to different positions, the torque caused by the center of gravity can affect the DD motor torque. If necessary, a brake can be installed.
Every HONPINE Direct Drive Motor undergoes comprehensive quality verification before delivery. Electrical performance, torque output, efficiency, temperature rise, and positioning accuracy are tested using professional laboratory equipment. Performance curves and inspection data are generated automatically, ensuring every motor meets the published specifications and delivers consistent performance in demanding industrial environments.
The protection rating for linear motors and DD motors is typically IP40 or IP20. Higher protection levels require customization. Additionally, the installation environment should be clean, free of iron filings, and away from magnetizable particles.
Linear modules and DD motors are generally used in high-precision applications. Maximum torque can be used for short-term load acceleration or deceleration, usually less than 1 second. Continuous torque is used for long-term load operation.
According to
F=ma and F=μmg, for the same acceleration and friction coefficient, the mass m of the load affects the thrust requirement of a linear module.
According to T=Iα, for the same angular acceleration, the rotational inertia of the load affects the torque requirement of a DD motor. Therefore, the closer the load is distributed to the rotational axis, the smaller the rotational inertia, and the lower the required torque.
For DD motors of similar size:
Inner-rotor DD motors have smaller rotational inertia and are generally used for small-load inertia, high-speed, and high-acceleration applications.
Outer-rotor DD motors have larger rotational inertia and are generally used for large-load inertia, medium-speed, and medium-acceleration applications.
In most cases, as long as the torque and speed are sufficient, inner-rotor and outer-rotor DD motors can be interchanged.
Yes, linear motors and DD motors can be used in cleanrooms. Many semiconductor applications already use linear motors. For example, in wafer fabrication plants, high-precision lithography machines are placed in Class 10 cleanrooms, and linear motors are applied in multi-axis positioning stages to achieve sub-micron accuracy with nanometer resolution.
A Direct Drive (DD) Motor is a precision rotary motor that drives the load directly without a gearbox, belt, or other mechanical transmission components. By eliminating mechanical backlash, DD motors deliver higher positioning accuracy, faster response, greater stiffness, and lower maintenance than conventional servo motor systems. HONPINE Direct Drive Motors are designed for applications requiring ultra-precise rotary motion, including semiconductor equipment, CNC rotary tables, optical inspection systems, medical devices, and industrial automation.
Every HONPINE Direct Drive Motor is validated with real laboratory testing rather than theoretical calculations. Using high-precision power analyzers and laser interferometers, we verify torque, speed, efficiency, temperature rise, positioning accuracy, repeatability, and angular accuracy before shipment. Complete performance curves and test reports ensure reliable and transparent product performance.
Compared with conventional servo motors and gearboxes, Direct Drive Motors eliminate mechanical transmission, resulting in zero backlash, higher positioning accuracy, faster acceleration, quieter operation, and lower maintenance. Their compact design also improves machine integration and simplifies cable routing, making them ideal for high-end automation and precision manufacturing.
Inner rotor motors offer lower rotor inertia and faster dynamic response, making them suitable for high-speed, lightweight applications. Outer rotor motors provide a larger effective radius and higher torque density, making them better suited for heavy loads and high-inertia rotary systems. HONPINE engineers can recommend the optimal configuration based on your torque, speed, and load requirements.
Positioning accuracy depends on the encoder resolution and application requirements. Every HONPINE Direct Drive Motor undergoes laser interferometer testing through a full 0°–360° rotation to verify angular accuracy, positioning accuracy, repeatability, and bidirectional positioning error. All published specifications are based on actual laboratory measurements.
