SteadyWin GIM3505-8 is a compact 8:1 planetary gear robot joint actuator for small articulated mechanisms, robotics prototypes and integrated motion-control systems. SteadyWin publishes current 24 V configuration data for GDS34 and GDZ34 drivers. The official figures below distinguish the GDS34 and GDZ34 configurations. The Shopify listing includes Motor Version and Driver options; use the selected configuration, not a generic motor type label, when matching control and mechanical resources. Features 8:1 planetary reduction - The official product table lists an aluminum planetary gear train with 15 arcmin backlash. Two documented 24 V configurations - SteadyWin publishes separate GDS34 and GDZ34 supply, torque, speed and communication entries. Configuration-specific output - The official table lists 0.65 N·m / 1.27 N·m rated and stall torque for GDS34, or 0.67 N·m / 1.79 N·m for GDZ34. CAN and RS485 option - GDS34 lists CAN, while GDZ34 lists CAN and RS485. 14-bit onboard encoder - Both documented configurations list 14-bit encoder resolution. Separate encoder support - SteadyWin lists separate encoder support for both GDS34 and GDZ34 configurations. Very compact body - The official dimensions are Ø43 × 23.6 mm without a driver and Ø43 × 30 mm with one. Published mechanical loads - The official table lists 75 N maximum axial load and 300 N maximum radial load. IP54 operating range - Both documented configurations list IP54, -20°C to +80°C and noise below 60 dB. Brake customization - SteadyWin lists custom brake support for both official configurations.
