A compact direct-drive servo motor integrating a brushless outer-rotor motor, encoder, and servo driver into a single unit. By eliminating the traditional gearbox/reducer, it delivers smooth torque, low noise, and long life in a smaller package.
The built-in driver uses a Field-Oriented Control (FOC) algorithm with a high-precision sensor for accurate speed, position, and current control. Communication over UART provides real-time motor data including position, speed, current, and fault codes.
Key Features
- Integrated Design – Motor, encoder, and driver in one compact unit
- Direct Drive – No reducer/gearbox, fast response with no mechanical delay
- FOC Control – Field-oriented control for precise operation
- Low Noise – 47.2 dB idle, 54.5 dB under load
- UART Communication – Read position, speed, current, and fault codes
- Hall Position Detection – Built-in sensor for accurate feedback
- Electric Braking – Active braking support
- Protection – Over-current, over-temperature, and stall protection
Specifications
- Working Voltage – 11–22 V DC
- No-Load Speed – 210 ±15 RPM
- Rated Torque – 0.25 Nm
- Stall Torque – 0.85 Nm
- Interface – UART
Ideal For
- Robot joints and articulated mechanisms
- Self-balancing robot drive wheels
- Small AGV (Automated Guided Vehicle) drive wheels
- Educational robotics platforms

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.
- Field-Oriented Control (FOC)
- Field-Oriented Control is a motor-control method that carefully controls the magnetic fields inside a brushless motor for smoother and more precise motion. It matters for projects such as robotics, gimbals, and haptics where quiet operation, low-speed control, or accurate torque control is important.
- servo motor
- A motor module that moves to a commanded angle rather than simply spinning freely. It matters for robotics and mechanisms because it is useful for steering, arms, gates and other parts that need controlled position.
- 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.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
