Product Description
PH series servos highly integrate the three major components of reducer, motor and drive to form an ultra-small integrated servo module. The joints adopt bus design and hollow wiring, which greatly simplifies the system structure. It adopts high-precision double magnetic design and optional brake to meet various harsh working conditions.

Size & Interface






Application Cases
The servo module adopts a hollow design, which is particularly suitable for the six-axis collaborative robot arm. The high-speed closed-loop cycle of the module can flexibly control the rigidity and precision of the robot arm, providing a high-performance body for the host computer. The robot joints with different loads can be freely combined, and the body and software technical support are provided, so that customers can quickly build their own robot system.
