Overview

The MyActuator RMD-X8-S2 Motor is a servo actuator motor from the RMD-X V3 Series, designed for compact, high-integration robotic joints and drive modules. The series highlights include small size, light weight, and high integration, with focus points such as multiple protections, low noise, high precision, good quality, and long service life.

Key Features

  • Control modes: Servo mode (Torque / Velocity / Position); Motion mode (feedforward torque/velocity/position)
  • Communication: CAN bus and RS485 bus (baud rates listed in Specifications)
  • Encoder function: Encoder multi-turn angle recording function; reserve data after power off
  • Second encoder support: Support install the second encoder (higher control accuracy)
  • Protection design: Overtemperature protection / Overcurrent protection / Overvoltage protection / Overspeed protection
  • Firmware/updates: Support remote update and update the latest firmware at any time
  • Temperature sensing: Support temperature sensor and the temperature can be read in real time
  • Mechanical: Double bearing construction; compression resistance; shock resistance; “20% performance increased”
  • Environmental design (statement from product material): Fully enclosed waterproof design; waterproof / dustproof / resists corrosion; need to be customized
