DD Motor
For various automation tasks. Hiwin's DD motor.
HIWIN DD motors adopt a direct drive system that does not require a reduction mechanism. The motor is rigidly coupled to the load through cross roller bearings, achieving excellent acceleration and motion stability through servo driver control. Cables and related accessories can be connected through a hollow shaft, making it suitable for a wide range of applications such as automation tasks. ■ No backlash ■ Hollow shaft ■ No rotational friction from gears ■ Compact ■ Maintenance-free ■ High rigidity cross roller bearings ■ Built-in brake available (optional) ■ Hall sensor available (optional) Product lineup: 【DMS Series】Inner rotor type DD motor 【DMY Series】Outer rotor type DD motor 【DMN Series】Thin outer rotor type DD motor 【DMT Series】Ultra-thin large hollow diameter DD motor 【DMH Series】Inner rotor type DD motor ○ For more details, please refer to the catalog or contact us.
