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.
