Feetech STS3045M 6V 6kg.cm Metal Gear Serial Bus Servo

The Feetech STS3045M is a compact smart servo for small robot joints, grippers, camera mechanisms and lightweight automation where a standard-size servo will not fit. Its coreless motor, metal gearbox and aluminium case weigh only 34.8g, and it is commanded and monitored over the TTL serial bus.

Key features

• 12-bit magnetic encoder: 4096 positions over 360°, with no potentiometer to wear

• 0-360° position control plus continuous multi-turn rotation for wheel-type drives

• Feedback of position, speed, voltage, current, temperature and load, with overload and over-current protection

• Coreless motor and ball bearings; 25T, 5.9mm OD horn spline

• Slim 36 x 15 x 29.2mm body

Specifications

• Operating voltage: 4.8-7.4V

• Peak stall torque: 6kg.cm at 6V

• Rated torque: 2kg.cm at 6V

• No-load speed: 0.133 s/60° at 6V

• Current: 120mA no-load, 1.4A stall at 6V

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

• Cable length: 150mm

• Dimensions: 36 x 15 x 29.2mm

• Weight: 34.8g (±1g)

• Operating temperature: -20 to 60°C

Its 4.8-7.4V range suits a 5-6V BEC or regulated supply; a fully charged 2S LiPo (8.4V) is above its rating.
