Overview
The DAMIAO DM-J10010L-2EC Robot Motor is an integrated motor and driver assembly designed for robotics applications requiring compact size, high torque density, and precise control. This Robot Motor features dual encoders that provide single-turn absolute position at the output shaft with no loss of absolute position after power-off. It supports host-computer visual debugging, firmware upgrades, and rich telemetry (speed, position, torque, and motor temperature) over CAN.
Key Features
- Dual encoders with single-turn absolute output shaft position; retains absolute position through power cycles.
- Integrated motor + driver for a compact, highly integrated actuator package.
- Host-computer visual debugging and firmware upgrade support.
- CAN bus telemetry for speed, position, torque, and motor temperature.
- Dual temperature protection.
