Applications

  • Propeller drives for light unmanned aerial vehicles.
  • Pump and propeller drives for unmanned watercraft.

Features

  • Excellent dynamic characteristics.
  • Regenerative braking and active freewheeling.
  • Continuous power output up to 350 W.
  • Extremely lightweight, only 10 g without wires.
  • Optional RPM control loop (RPM governor).
  • Embedded self diagnostic routines and health status reporting.
  • Highly configurable.
  • Low noise and low current ripple.
  • Supported interfaces:
    • CAN (UAVCAN), with optional dual redundancy.
    • UART.
    • RCPWM (analog PWM interface widely used in robotics).
  • High quality assurance:
    • Every manufactured unit undergoes a rigorous testing procedure. The testing log for each produced unit is available on the web.
    • Protection against unlicensed (counterfeit) production by means of a digital signature installed on every manufactured unit.
  • Open source firmware – Sapog (3-clause BSD license).
