Main Features

n KGM series integrated Harmonic Drive Rotary Actuators, which consist of high precision harmonic drive reducer, Frame-less torque motor, motor shaft encoder, output shaft absolute encoder, servo drivers, brake and intelligent sensor etc, which supports personal customized design and development.

n It supports EtherCAT or CANopen bus type communication protocols, which can be matched with mainstream robot controllers on the market.

n Dozens of product models are available to meet diversified needs.

n High torque output with average torque up to 557N·m (model KGM-40), which is suitable for collaborative robots with effective load less than 25 kg.

n The rated speed can be as high as 88 rpm (model KGM-14).

n The positioning precision of integrated Rotary Actuators is within 50 Arc sec.

n Compact structure and light weight. For example, the weight of KGM-14 is less than 1.8 kg.

n An internal through-hole is set to facilitate threading of wires, gas pipe and laser beams, which simplify the system structure.

n High protection grade (IP65 or IP67) makes the product applicable to severe working environment.
