HMHG-V Unit (Hollow & Long Shaft) Series Harmonic Drive

HMHG-V Series with hat-combination standard structure. The input shaft can
connect with the motor directly. The cable can go through the low-speed hollow
shaft Encoder can be installed on both input and output shafts Especially for
Cobot and Joint modular

Features of HMHG-V Unit (Hollow & Long Shaft) Series Harmonic Drive

The cable can go through the hollow shaft, safer and more reliable

Doubled torque/volume ratio, as well as modular design, make it more compact
with motor

No Backlash

Excellent positioning accuracy and rotation accuracy

Run out is smaller for install position of motor and encoder

30%higher torque capacity than the HMHS series

43%longer lifetime than the HMHS series
