Overview
The SteadyWin GIM8115-9 Planetary Reducer Motor is a compact, high-torque robot motor with an integrated 9:1 planetary gearbox for use in demanding robotic joints and drive modules. With a power range of 190W to 245W, steel planetary gears, integrated driver options (SDC103 and SDC303), 14-bit encoder feedback and IP54 protection, it is suitable for applications requiring precise, low-backlash motion control in a 24-48V system.
Key Features
- Integrated 9:1 planetary reducer with steel gears and approximately 15 arcmin backlash for precise positioning.
- Power range from 190W to 245W with nominal torque from 12.9 N.M to 13.8 N.M and stall torque from 39 N.M to 49 N.M across variants.
- Nominal output speed after reduction from 100 RPM to 136 RPM and maximum speed after reduction from 129 RPM to 160 RPM.
- Supports 24 V and 48V bus systems (24-48V and 15-48V ranges depending on driver configuration).
- Low noise operation, specified at <60dB.
- High-load mechanical design with up to 225N max axial load and 900N max radial load.
- CAN and 485 communication options depending on variant, with second encoder support indicated as YES.
- Built-in 14Bit encoder, with separate encoder support specified as NO and custom brake support specified as YES.
- IP54 protection grade and -20°C to +80°C operating temperature range for use in varied environments.
- Compact motor dimensions from approximately Dia 96*41mm (without driver) and Dia 96*48.5mm (with driver), with motor weight from 660g to 705g.
