The DYNAMIXEL DRIVE (DYD) is a built-to-order product and requires a lead time of 7 weeks.


The DYNAMIXEL DRIVE (DYD) is a High-Precision gear with Superior Impact Resistance. 

Generally, a traditional Cycloidal Gear Drive is well known as being strong but larger in size and heavier compared to the Harmonic Drive. However, unlike traditional Cycloid Drives, the ROBOTIS DYNAMIXEL DRIVE(DYD) achieves high torque and accurate repeatability at the same time while being more compact, lighter, and stronger over other reducers in the market.
