Overview

The LKMTECH MG4005-V2 Motor is a brushless motor module designed for robotics actuation. It integrates a PG4210 planetary reducer (1:10) and an 18-bit magnetic encoder, with communication via RS485 or CAN for closed-loop torque/speed/position control.

Key Features

  • High power brushless motor
  • High precision planetary reducer: backlash ≤10 arcmin, ratio 1:10
  • 18-bit single ring absolute encoder; one calibration, zero position is retained after power loss
  • Communication: CAN or RS485
  • Drive input voltage: 7.4-32V
  • Main control: 72MHz main frequency with 32-bit ARM
  • Supports PWM input; optimized motor cogging torque for smoother operation
  • Motor tool software support: parameter adjustment, testing, and firmware upgrade
  • Supports open-source development platforms such as PC, MCU, PLC, ICP and RPi
