STS3045M TTL Serial-Bus Smart Servo with 6 kgcm Torque, 12-Bit Magnetic Encoder and Aluminium Case
The STS3045M is a digital serial-bus smart servo designed for robotics, industrial equipment, automation systems, and compact drive mechanisms requiring accurate position and motion control. At 6V, it delivers up to 6 kg.cm peak stall torque with a no-load speed of 0.133 sec/60deg. Its 12-bit magnetic encoder provides 4096-position resolution over 360deg, enabling precise angular control without relying on a conventional potentiometer.
The servo combines an aluminium-alloy case, metal gearbox, coreless motor, ball bearings, and FEETECH TTL control electronics in a compact package. It supports 0-360deg position control as well as continuous multi-turn operation for applications requiring wheel-like rotation. Position, speed, voltage, current, temperature, and load monitoring provide useful system feedback, while overload and over-current protection help protect the servo during demanding operation.
