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.
