Overview
The FEETECH STS3250 Servo Motor (model ST-3250-C001) is a digital TTL serial Servo Motor featuring a magnetic encoder and double shaft design. It uses a coreless motor with steel gears and ball bearings in an aluminium case, providing high peak stall torque of 50kg.cm@12V and fast response at 0.133sec/60°@12V. The servo supports half duplex asynchronous serial communication with ID addressing and returns rich feedback including load, position, speed, input voltage, and temperature.
Key Features
- Magnetic encoder with 360° operation (when 0~4096); neutral at 180°(2048)
- Double shaft, 25T/OD5.9mm horn gear spline
- Coreless motor, steel gear train, ball bearings, aluminium case
- Operating voltage range: 6-12V; stall current: 4.2A@12V
- Peak stall torque: 50kg.cm@12V; rated torque: 16kg.cm@12V
- No-load speed: 0.133sec/60°@12V; running current (no load): 280mA@12V
- Digital Packet command signal; half duplex asynchronous serial protocol
- Adjustable ID range 0-253; communication speed 38400bps ~ 1 Mbps
- No limit angle; connector wire length 15cm
