LORDWORLD

LORDWORLD ST3025 Serial Bus Servo 40kg.cm 360° Magnetic Encoder 253 Servos

SKU CH-3MZJ-ZCM3B

A serial bus servo delivering 40 kg·cm torque with a 360° magnetic encoder and brushless motor, controllable alongside up to 253 units via UART

  • High torque of 40kg.cm for heavy loads
  • 360° programmable magnetic encoder enables precise positioning
  • UART serial bus controls up to 253 servos simultaneously
  • Settable acceleration and speed for smoother motion
  • Real-time feedback on position, load, speed, voltage, current and temperature

High-torque serial servo for robotics

The LORDWORLD ST3025 is a 40 kg·cm serial-bus servo built for robotics and automation projects that demand strong, repeatable motion. Its brushless motor and all-metal case suit developers who need durable actuation in jointed arms, humanoid platforms or custom mechanisms.

Thermal and power behaviour in normal use

The brushless motor runs cooler than brushed alternatives during sustained loads, keeping temperature rise modest in typical joint cycling. Two-way feedback streams real-time voltage, current and temperature so the controller can throttle before overheating becomes an issue.

253-servo bus capacity decides fit

A single UART line can address up to 253 servos simultaneously, so the limiting factor for large builds is the bus count rather than torque or resolution. Projects that need more than 253 nodes on one serial line will require additional controllers or a different topology.

Preguntas sobre este artículo

How do I wire the ST3025 servo on a UART bus without address conflicts?

Connect the servo to a UART serial bus and assign each unit a unique ID; the bus supports up to 253 servos simultaneously, so duplicate IDs are the step most users get wrong.

What parts of the ST3025 will wear out and need replacement?

The brushless motor and magnetic encoder have no brushes or pots to degrade, but the metal gear train and output shaft bearings are the mechanical components that eventually require service.

At what torque does the ST3025 hit its thermal limit during continuous operation?

Sustained loads near the 40 kg·cm rating raise internal temperature; the servo reports real-time temperature feedback so you can throttle before the protection circuit engages.
