Overview
The SteadyWin GIM8108-36 Planetary Reducer Motor is a high-torque Robot Motor combining a 36:1 planetary gearbox, 14Bit encoder feedback and robust mechanical design for precise motion control. With two driver options (SDC103 and SDC303), it covers 24–48 V supply ranges, delivering up to 192W power, high stall torque and low backlash performance for demanding robotic joints and drive modules.
Key Features
- Robot Motor with integrated 36:1 planetary reducer and steel gears for high torque transmission.
- Two electrical configurations: 48 V (SDC103) up to 192W and 24 V (SDC303) up to 120W.
- Nominal torque up to 35.1 N.M and stall torque up to 109.5 N.M for heavy-load applications.
- Low output speed after reduction (nominal 48–51 RPM, max 56–60 RPM) for accurate position and speed control.
- 14Bit encoder resolution with second encoder support (no separate external encoder support).
- Planetary reducer backlash of 15 arcmin for improved positioning accuracy.
- Mechanical robustness with 250 N max axial load and 1000 N max radial load.
- Protection grade IP54 and operating temperature range from -20°C to +80°C.
- Communication via CAN & 485 (SDC103) or CAN (SDC303) for system integration.
- Noise level <65 dB for use in noise-sensitive environments.
