Feetech ST-3095-C001 7.4V 95kg.cm Dual-Shaft Steel Gear TTL Servo

The Feetech ST-3095-C001 is a heavy-duty smart servo for large robot joints, arm shoulders and load-bearing mechanisms. A steel gearbox, ball bearings and dual output shafts in an aluminium case take the load, while the TTL serial bus provides closed-loop control and live feedback over a single controller line.

Key features

• Up to 105kg.cm stall torque when run at 8.4V, with 35kg.cm rated torque

• Dual output shafts with a 15T, 7.6mm OD horn spline

• 12-bit magnetic encoder: 4096 positions over 360°

• Absolute 0-360° position control, multi-turn operation, closed- and open-loop speed modes and step movement

• Feedback of load, position, speed, voltage, current and temperature

Specifications

• Stall torque: 95kg.cm at 7.4V; 105kg.cm at 8.4V

• Rated torque: 35kg.cm at 8.4V

• No-load speed: 0.286 s/60° at 7.4V; 0.25 s/60° at 8.4V

• Current at 8.4V: 800mA no-load, 10.5A stall

• Motor: cored DC motor

• Interface: half-duplex asynchronous serial (TTL), IDs 0-253, 38,400 bps to 1 Mbps

• Lead length: 150mm

• Dimensions: 30 x 65 x 48mm

• Weight: 194.5g (±1g)

• Operating temperature: -20 to 60°C

Stall current reaches 10.5A at 8.4V, so use heavy-gauge power leads and size the supply or BEC for the worst case of several joints stalling together.
