Overview
The RCDrone TS9035-36 MIT drive servo gear motor actuator is a compact, high-torque joint module designed for robotic arms, quadruped robots, inspection robots, and exoskeletons. With a rated torque of 35N·m, peak torque of 45N·m, and a 1:36 reduction ratio, it ensures precise torque output and stable operation. Operating at 48V, it delivers 800W rated power with 6.9A current and supports FOC control. The actuator offers dual/single encoder options:
-
Dual encoder → retains zero position after power-off.
-
Single encoder → zero position lost after power-off.
Equipped with RS485/CAN bus communication, 18-bit + 14-bit high-resolution encoders, and a compact 99mm × 53.5mm housing weighing just 860g, this actuator provides lightweight yet powerful motion solutions.
