What is Direct Drive (DD) Motor?
Sinfonia Technology – DD Motor can transmit the torque of the electric motor directly to the driving objects. Without the use of any reductions such as belts, pulleys or reduction drives
● High Efficiency ● Low Noise ● Outstanding precision ● High Reliability ● Maintenance Fee
1. Outer Rotor Mechanism
- The outer diameter’s compact design enables to drive directly the roller, making it suitable for indexing rotation
2. High Resistance Bearings
- Simple and rigid structure for a higher load resistance
3. Hollow Diameter ɸ 50 mm
- Wiring and piping can be easily stored in the hollow space of the motor, reducing the installation space.
4. Low Price
- Model’s size reduction leads to a more competitive price matching today’s market needs.

Thanks to the outer motor, it’s possible to build the motor inside the roller, saving space. So, it can work smoothly, avoiding uneven operations or movements
*Applications :
● Printing Equipment
● Coating Machines
● Films-Manufacturing Machinery
● Roll-feeders
Space-saving design for a more compact structure. As no reduction device is needed, hence it’s possible to avoid complex installations, improving its efficiency and reliability with no back lash
*Applications
● Semiconductor making equipment
● Devices for manufacturing
● Liquid Crystal Display Panels
● Assembling Robots
● All kinds of indexing applications
