Myxa in the aluminum heat-sinking enclosure

Myxa

High-end PMSM/BLDC motor controller (FOC 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 (UAV), underwater, and surface vehicles. The controller provides up to 850 W of continuous power output and supports a wide range of operating voltages 12–51 V (LiIon 4–12 S).

State-of-the-art vector control algorithms make Myxa one of the most energy-efficient ESC on the market. In the UAV field, the vector control technology is also known as field-oriented control, sine wave drive, or just FOC. Unlike other vector control 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 (drones).
  • Pump and propeller drives for unmanned watercraft.
  • Fuel pump drives for jet engines and gas turbines.
  • CMG drives for LEO spacecraft.

Features

  • Based on the advanced Télega motor control technology.
  • Continuous power output up to 850 W.
  • Single supply voltage 12–51 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 via external thermistor.
  • Connectors compatible with the Dronecode Autopilot Connector Standard.
  • Standard 3.5 mm bullet power connectors.
  • High quality assurance:
    • Every manufactured unit undergoes a rigorous automated 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.

Variants

Two types of Myxa are available:

  • Myxa A - optimized for cost-sensitive applications.
  • Myxa B - optimized for mission-critical applications.

Each type is available in several modifications which are reviewed in the table. Regardless of the chosen enclosure option, all versions of Myxa are conformal-coated, which provides resilience against moisture, aggressive chemicals, corrosion, and abrasion.

RPM Control Mode

Hello, I am using Myxa to control the motor in RPM via PWM. I did an endurance test on my system and I observed that the RPM is not constant during the mission and decrease with the tension of the battery. The current should increase to keep the same power. The Myxa is configure to RCPWM control mo…

Max RPM still low after max_eangvel

Setup: 12n14p motor 470kv, 22.2V regulated power supply (im running at 22.2V so I know that I can reach the desired max RPM with a discharged pack voltage) I’m getting a max RPM of about 7600 with the max_eangvel set to 20000 in control mode 2. The motor is 12n14p 470kv and is set correctly to 14 …

Fine motor control using Myxa or Komar ESC

Hello everyone, I’m quite new to building quadplanes, but was wondering if it was possible to alter the min_eangvel value via CAN protocol, similar to what we can do via USB with the Kucher software? I’m wanting to spin the motor at around 50 RPM using Ardupilot, so was wondering if this functiona…

Control Myxa with traditional CANbus protocol?

I’m an electrical engineer working on a project where we may need to use your Myxa ESC as a backup controller for an air compressor motor in our system if the BLDC on the prototype controller we’re having developed doesn’t pan out. The controller we’re getting utilizes traditional CANbus protocol in…

CSSW Displaying Saturated

Greetings I was running Mxya today on a 7S Li-ion pack with a KDE3520XF-400 (400KV) motor with an APC 12x12 prop connected. I expected to reach a slightly higher RPM, but I noticed CSSW indicates ‘Saturated;’ please see the attached screensnap for reference. Doing some calcs, I notice the voltage …

Myxa high torque application

Hi everyone, We have a somewhat unique multirotor propulsion system and are therefore using Myxa to drive a 240Kv motor in a unique work regime - very low RPM (~1000) and high torque. Generally speaking and without getting into the details - what is the preferred control method to be working with …

Disable regenerative braking

Hi, I work on the definition of a new Tethered UAV and I am thinking of using Myxa ESC. But our power supply cannot take any reverse current. Is it possible to disable regenerative braking on Myxa or will we have to design a protection system to dissipate energy coming back? Thanks…
