Description
The DAMIAO DM40-1E is a compact FOC servo driver designed for robotic joint actuators, BLDC motors, gimbal systems, and lightweight robotic arms. Built around a Cortex-M4 MCU running at 200MHz, the controller supports MIT Mode, Velocity Mode, and Position Mode while providing CAN bus communication and UART parameter configuration.
Designed specifically for 35mm–43mm class motors, the DM40-1E supports dual encoder feedback architectures including dual magnetic encoders and magnetic encoder plus Hall sensor configurations. This enables precise motion control, smooth torque output, and reliable closed-loop positioning for robotics and automation applications.
The integrated Field-Oriented Control (FOC) algorithm delivers high efficiency, low vibration, and accurate motor control suitable for AGV robots, robotic joints, exoskeleton systems, pan-tilt platforms, and research robotics projects.
