Direct Drive Torque Motor 

HONPINE specializes in the R&D and manufacturing of direct drive torque motors, having established a 5,000-square-meter facility dedicated to the development, production, and administration of its direct drive motor product lines. The facility is equipped with a comprehensive array of advanced machinery, including dynamometers, fully automated winding machines, CNC machining centers, laser interferometers, automated potting machines, and salt spray test chambers. Furthermore, the company has established sales and after-sales service centers in Singapore, Suzhou, and Shenzhen. To support the localization of semiconductor equipment manufacturing, the company commissioned a precision assembly cleanroom and an R&D laboratory in 2024. HONPINE has successfully obtained quality certifications such as ISO9001 and CE, and its independently developed products have been awarded dozens of patents for both inventions and utility models.

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

Direct Drive Motor-FAQ

A：

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.

A：

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.

A：

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.

A：

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.

A：

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.

A：

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.

A：

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.
