Myxa

High-end PMSM/BLDC motor controller (ESC) for light unmanned aircraft and watercraft.

Myxa is a high-end FOC ESC based on the Télega motor control technology.

Myxa is designed for use in propulsion systems of light unmanned aerial, underwater, and surface vehicles. The controller provides up to 600 W of continuous power output and supports a wide range of operating voltages 12–50 V (LiIon 4–12 S).

State-of-the-art vector control algorithms make Myxa one of the most energy-efficient ESC on the market. Unlike other solutions, Myxa is compatible with virtually any PMSM or BLDC motor, and is able to measure the parameters of the driven motor and automatically optimize itself for best performance.

Applications

  • Propeller and fan drives for light unmanned aerial vehicles.
  • Pump and propeller drives for unmanned watercraft.
  • CMG drives for LEO spacecraft.

Features

  • Based on the advanced Télega motor control technology.
  • Continuous power output up to 600 W.
  • Single supply voltage 12–50 V (Li-ion 4–12 S).
  • Rich set of communication interfaces:
    • CAN bus interface (connectors are compatible with UAVCAN and the Dronecode Autopilot Connector Standard). Myxa B offers a doubly-redundant CAN bus interface for mission-critical applications.
    • UART interface for control, management, and telemetry.
    • USB interface for control, management, and telemetry; driverless compatibility with GNU/Linux, Windows, Mac OS X. The connector type is USB Micro-B.
    • Industry-standard RC PWM input.
  • 5V BEC (battery elimination circuit) power output (Myxa B only).
  • Optional motor temperature measurement.
  • Connectors compatible with the Dronecode Autopilot Connector Standard.
  • Bullet 3.5 power connectors.
  • 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.
