UAV Projects

We offer customized speed controllers for BLDC/PMSM motors used (not only) in UAVs as starters combined with electric generators. With integrated telemetry and various possibilities of optional user configuration, the controllers offer high efficiency, low weight and precise motor control.
We offer two possible solutions:

Electric Starter

  • Combustion engine startup using a gearbox-equipped brushless motor (BLDC).
  • Automatic startup sequence with appropriate safety mechanisms.
  • 8 – 32V, 50A active current limiting.
  • Optically isolated control inputs:
    • PWM/servo signal to control the motor start sequence.
    • RPM input from the engine control unit as a part of the safety mechanisms.

Please contact us for further details.

 

Electric Starter-Generator

  • Combustion engine starter and electric generator in a single box. A BLDC motor is directly mounted on the engine shaft.
  • Hybrid operation possible: battery charging in generator mode, alternatively a function of an auxiliary electric motor to increase the overall power of the propulsion system (boost).
  • Automatic startup sequence with the appropriate safety mechanisms.
  • Autonomous operation in the Generator mode with configurable RPM-to-current curve.
  • Modified IBEX controllers support the starter-generator mode. Basic types:
    • IBEX 130: 12-51V (12S LiPo), peak 130A. Optically isolated control input (startup sequence and proportional current control).
    • IBEX 200: 12-59V (14S LiPo), peak 200A. Galvanically isolated control input (startup sequence and proportional current control). Automatic engine RPM control using a dedicated throttle servo output.
  • Automatic charging of the main LiPo battery (12S or 14S) using a configurable RPM-dependent current curve. The charging current is reduced as soon as the battery voltage reaches the user-defined target voltage.
  • Operation always with a battery.

Please contact us for further details.

 

Standalone Generator Mode

  • In cases where the starting sequence for spinning up the engine is not required, the generator-only mode can be utilized without the starter function.
  • Other features are identical to the starter-generator mode.
  • Regenerative braking function.

 

IBEX 130: 3D

Common features

  • Small dimensions and high power motor control.
  • Over- and undervoltage protection, overtemperature protection, motor-stall protection.
  • Configurable current limiter.
  • Optically isolated throttle input (PWM 1.0-2.0ms).
  • Safety shutdown when the throttle impulse is lost.
  • Configurable acceleration, charging current, charging ramp.
  • Low acoustic noise due to high frequency switching.
  • Online telemetry (several UART-based protocols supported): voltage, current, power, capacity, temperature, RPM, energy.
  • Telemetry min/max values are logged.
  • Configuration through the MAV Manager PC software or an external terminal (JETIBOX).
  • Firmware updates via USB interface.
  • Languages: CZ/EN.

 

 

EFI: Electronic Fuel Injection System

The electronic fuel injection system represents an advanced way of controlling gasoline engines. With integrated telemetry and various possibilities of optional user configuration, the unit offers high efficiency, low weight and precise engine control.

The control unit has been specifically designed for UAVs, enabling high altitude flight. It ensures quick engine start even at cold temperatures, providing more power and torque compared to the carbureted version. The EFI system offers high fuel efficiency and produce low carbon emissions. It includes on-board diagnosis capabilities and allows for performance tuning, catering to the needs of advanced users.

The fuel injection system is produced through an exclusive partnership cooperation.

Features

  • Small dimensions combined with efficient engine control.
  • 1 – 4 injectors connection, up to four-cylinder engines are supported.
  • 1 – 2 ignition modules can be connected.
  • Up to 5 temperature inputs (type ”K” thermocouple): CHT1-4, EGT.
  • Fuel pump connection and automatic fuel pressure control.
  • Barometric altitude compensation.
  • Wideband Oxygene sensor support, based on Bosch LSU 4.9.
  • Digital inputs: Engine stop, engine mode binary switch.
  • All system voltages are monitored.
  • Safety shutdown when the throttle impulse is lost.
  • Configurable acceleration, injection parameters, throttle range, governor, feedback control based on oxygene sensor etc.
  • UART or DroneCAN Bus communication.
  • Telemetry: supply voltage, current, temperature 1-5, internal temperature, RPM, fuel pressure, lambda value, injection length.
  • Engine consumption measurement.
  • Telemetry min/max values are logged.
  • Configuration through the MAV Manager PC software or Ardupilot.
  • Firmware updates via USB interface.
  • Languages: CZ/EN.
  • Design and manufacturing in the Czech Republic, European Union.
