ST3025 serial bus servo designed for applications that require torque, precise position feedback, and flexible control. Metal case, brushless motor, and a programmable 360 degrees magnetic encoder provide smooth operation, durability, and reliable twoway feedback. Switchable between servo mode and motor mode for greater versatility. Key benefits torque for demanding tasks: 40 kg.cm at 12 V delivers strong output for robotic joints, grippers, and drive mechanisms. precision full rotation control: programmable 360 degrees position with 4096 steps gives 0.088 degrees resolution for accurate positioning and repeatability. Robust construction and long life: metal case and precision steel gears withstand mechanical load while maintaining smooth motion. Wide voltage range and strong current handling: operates from 6 to 12.6 V (typical 12 V) and supports up to 4.4 A lockedrotor current for heavy loads. Twoway feedback and flexible communication: reports position, load, speed, input voltage, current, and temperature while using serial bus communication with adjustable baudrate and ID addressing. Mode flexibility: switch between servo mode and motor mode to match control strategies for different applications.
