Open Source Brushless Servo

The odrive is a open source high performance brushless servo platform based on RC BLDC motors. Great Stuff!

Key Specs

  • Two motor channels.
  • 24V, designed for more than 100A peak current.
    • 48V version just released.
  • DC-DC converter, for brake resistor or energy storage.
  • Encoder feedback for arbitrarily precise movements.
  • Supports power regeneration.
  • Optional use of a high power density battery means you can achieve >1kW peak power output with only a modest power supply.
  • Open source: HardwareSoftware

Interfaces

  • USB Serial port — PC, BeagleBone, RaspberryPi, etc.
  • CAN — CANOpen and CiA 402 is a possibility.
  • UART — Arduino, mBed, etc.
  • PWM — RC Recievers, Arduino, etc.
  • Step/direction — Existing motion controllers
  • Some general purpose digital and analogue pins

Protocols

  • Many types of command modes
    • Goto (position control with trajectory planning)
    • Position commands
    • Velocity command
    • Torque command
