DAMIAO DM-J10422P-2EC Motor 48V CAN 5Mbps UART 921600bps Dual Encoder 1:22 Gear Motor

Overview

The DAMIAO DM-J10422P-2EC Motor is a 48 V geared motor with dual encoders, designed for closed-loop motion control via CAN (up to 5 Mbps) and tuning via UART (921600 bps). It supports MIT Mode, Velocity Mode, Position Mode, and Torque Control Mode.

Application Scenarios

• Humanoid robots
• Robotic arms
• Exoskeletons
• Quadruped robots
• AGV vehicles
• ARU robots

Key Features

• Nominal voltage: 48 V
• Dual encoders: 2 encoders, 17Bit resolution, ±0.03 degrees accuracy
• Control interface: CAN@5Mbps (Max)
• Tuning interface: UART@921600bps
• Control modes: MIT Mode / Velocity Mode / Position Mode / Torque Control Mode
• Reduction ratio: 1:22
• Integrated protection functions (over-temperature, over/under-voltage, over-current, communication loss)

Specifications

Protection

• Driver over-temperature protection: Protection temperature is 120°C. The motor will exit "Enable Mode" when over-temperature occurs.
• Motor over-temperature protection: Can be set according to usage requirements. Recommended not to exceed 100°C (setting above 110°C may burn the coil). The motor will exit "Enable Mode" when over-temperature occurs.
• Motor over-voltage protection: Can be set according to usage requirements. Recommended not to exceed 65V. The motor will exit "Enable Mode" when over-voltage occurs.
• Communication loss protection: The motor will automatically exit "Enable Mode" if no CAN command is received within the set period.
• Motor over-current protection: Can be set according to usage requirements. Recommended not to exceed 0.98. The motor will exit "Enable Mode" when over-current occurs.
• Motor under-voltage protection: If the power supply voltage is lower than the set value, the motor will exit "Enable Mode" (power supply voltage shall not be lower than 20V).
