This heavy-duty PWM servo is built for high-load motion control where torque, durability and repeatable positioning matter. It uses a 24V brushless motor with a 12-bit magnetic encoder to deliver up to 450kg·cm stall torque and precise angular feedback.
The sealed aluminium alloy housing, hardened steel gear train and IP65 protection make it suitable for harsh environments with dust, moisture, vibration and mechanical stress. It is intended for demanding robotics joints, automated machinery, outdoor electromechanical systems and marine control assemblies.
Closed-loop PWM control and contactless magnetic sensing help maintain positioning accuracy across the servo’s 180° operating range. The package includes the servo and a servo horn screw accessory kit.

Jargon buster
Plain-language definitions for the technical terms used above.
- AGV
- An AGV, or automated guided vehicle, is a mobile robot used to move materials without a human driver. This matters because controllers used in AGVs need reliable communication and industrial I/O for motors, sensors, and safety systems.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- kg·cm
- A torque unit often used for hobby servos, meaning how many kilograms of force the servo can hold at a 1 cm arm length. A higher kg·cm rating means the servo can move or hold heavier loads, but power supply current needs may also increase.
- Matter
- A smart home connectivity standard designed to let devices work across different ecosystems. It matters if you want a project to integrate more easily with platforms such as Apple Home, Google Home, or other Matter-compatible systems.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- Stall torque
- The maximum twisting force a servo can produce when its output is held still and cannot move. It helps you judge whether the servo is strong enough for a robot joint, steering linkage, or other load.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
