Overview
The SteadyWin GIM3505-8 is a planetary reducer motor with an 8:1 planetary gearbox, designed for compact robotic actuation where controlled speed and torque are required. Two driver configurations are specified (GDS34 and GDZ34), with communication options of CAN, or CAN & RS485 depending on the driver model.
Applications
- Humanoid robots
- Robotic arms
- Exoskeletons
- Quadruped robots
- AGV vehicles
- ARU robots
Key Features

- Nominal voltage: 24 V (12–48 V range with GDS34; 12–40 V range with GDZ34)
- Integrated encoder resolution: 14-bit
- Protection grade: IP54
- Noise: <60 dB
- Separate encoder support: YES
- Custom brake support: YES
- Second encoder: NO
- Communication (by driver model): CAN (GDS34) or CAN & RS485 (GDZ34)
