Frequently Asked Questions
A harmonic drive (strain wave gear) provides high reduction ratios in a compact, lightweight package with zero backlash, which is why it is the standard gearbox for robot joints. Our DATORKER® Harmonic Drives deliver high torque density and precision.
The Lightweight Series Harmonic Drive is available in reduction ratios from 30:1 to 160:1 (and higher), with near-zero backlash. Select the ratio based on your speed and torque requirements — our engineers will confirm the right configuration.
Cup and hat types offer different shaft arrangements and stiffness for robot joints, while pancake types provide an ultra-thin profile for space-constrained applications. We recommend the best Harmonic Drives structure for your mechanism.
Selection is based on peak torque, average torque, speed, and the required life. Send us your motor torque, output requirements and duty cycle, and we will provide a sizing recommendation for Harmonic Drives.
Yes. We can supply Harmonic Drives integrated with servo motors, brakes and encoders as ready-to-install actuator units, reducing your assembly work and ensuring matched performance.
