Télega

State-of-the-art PMSM/BLDC motor control solution for aerospace applications and robotics.

Télega is an advanced electric motor control solution (PMSM/BLDC) for aerospace and robotic applications. Telega implements breakthrough approaches to digital signal processing that enable high energy efficiency and excellent dynamic characteristics. Telega supports a wide variety of communication interfaces and auxiliary features that enable easy integration into the end application.

Performance

Télega employs new approaches to digital signal processing (DSP), which in combination with a proprietary field-oriented control (FOC) algorithm enable a significant improvement in energy efficiency, better dynamic characteristics and higher robustness compared to traditional PMSM/BLDC drives, including modern vector control solutions from other vendors.

Higher energy efficiency and the resulting decrease in heat dissipation allows Télega-based drives to achieve higher power output in smaller form factors.

Built-in robust motor identification routines ensure compatibility with virtually any PMSM or BLDC motor with minimal manual tuning required.

Versatility

Supported communication interfaces:

  • CAN bus with optional dual bus redundancy for safety-critical applications.
  • USB (driverless compatibility with Windows, GNU/Linux, and OSX).
  • RC PWM for UAV/robotic applications.
  • UART and RS-232.
  • Scriptable GPIO and analog interfaces (coming soon).
  • Support for analog motor temperature sensors.

Telega-based motor controllers supports in-field firmware upgrades via CAN bus, USB, and UART/RS-232 – no special tools needed.

Reliability

Robust sensored and sensorless operation even with poorly characterized (low cost) motors.

The hardware implementations are made to withstand harsh environments and extreme operating conditions.

Every manufactured unit undergoes a rigorous automated testing procedure. The test reports are available online for every delivered device. Extended traceability data is available upon request.

Applications

  • Propeller and fan drives in electric aircraft (manned/unmanned).
  • Pump and propeller drives in electric watercraft.
  • Fuel pumps for jet engines and gas turbines.
  • Propulsion systems in ground robots and EVs.
  • CMG drives for small satellites.

There are motor controllers and integrated drives that cover a wide range of power levels and different application domains. We also design custom electric propulsion solutions for our customers.

High Power Motor Tuning Guide

Hi there, We have a mitochondrik design in the realm of the Komar ESC. We are having trouble getting a much larger motor to start reliably, and the myxa quickstart guide does not seem to cater to this sort of use case. The motor is consuming an average of ~1kW of power I took reference from this to…

Myxa controlled braking before spinup

Hi All, In my setup Myxa is connected to a Tmotor MN501 BLDC. To begin with - the Myxa is recieving 0 input and the motor is freewheeling in the reversed direction due to a small torque applied to it. When I’m applying an input to the Myxa, it rapidly brakes and changes direction and begins spinu…

RPM Software Estimation in Mitochondrik Telega

Hello, I was wondering how the Mitochondrik calculates RPM feedback of the motor since I read that the Mitochondrik is sensorless and doesn’t include a sensor for RPM feedback. Is there a document available which explains the RPM sensorless feedback calculation? Does Telega handle the RPM calculatio…

Myxa Field weakening

Hello guys ! I’m using the Myxa 0B with telega v0.2 for a quad copter UAV. I’m very please with the ESC controler and its small SWAP. I’m using a lithium-ion battery (full charge: 25.2V - empty: 18V) and due to it’s low empty voltage (compare to a classic lipo : empty voltage ~20.5V) the motor can’…

Data acquisition via USB

Hello everybody! I just bought some Myxa A2 ESC, and I have 2 questions: I am using it via USB on Windows at the moment, but I also have ubuntu. I am wondering if there is the possibility of acquiring data that are showed in the Kucher window while running the motors. Moreover, I am looking for a…
