SteadyWin GIM3505-8 Built-in Planetary Reduction Motor — Quadruped Robot Joint Module, 8:1 Gear, 24V, CAN, IP54

Overview

SteadyWin GIM3505-8 built-in planetary reduction motor quadruped robot joint module designed for compact robotic joints and actuator assemblies. The GIM3505-8 integrates an 8:1 planetary reducer with a brushless motor and onboard driver options to deliver controlled motion for quadruped robots, robotic arms, humanoid joints and similar mechatronic systems.

Key Features

• Advanced planetary gear system for low backlash and smooth motion (gear backlash: 15 arcmin).
• Broad voltage adaptability: rated voltage 24 V with an operating range of 12~48 V.
• High torque density and efficiency: torque constant 0.52 N·m/A with rated torque 0.65 N·m and peak torque 1.27 N·m.
• Compact footprint: Ø43 × 23.6 mm (without driver); Ø43 × 30 mm (with driver).
• Integrated safety protections: over-temperature, over-voltage and overload safeguards (triple-layer protection stated in product literature).
• CAN communication interface; supports separate encoder and optional custom brake.
