The first drone to fly on Mars.

In April 2021, NASA's Ingenuity helicopter successfully completed its pioneering flight on Mars. Six specifically modified maxon micro motors control the helicopter`s flight direction. The lightweight and reliable design was a prerequisite for a successful flight on Mars, where there is hardly any atmosphere.

Tested a million times.

Any new UAV component undergoes a series of qualification tests before release, assuring utmost safety through a strict quality system.

Quality you can rely on

Unmanned aerial vehicles require reliable components and, above all, energy-efficient drives that ensure the longest possible flight time. maxon brushless DC motors and ESCs meet these requirements without difficulty. maxon guarantees the unrivalled quality of its efficient, reliable and powerful propulsion systems for the drone industry. maxon has been EN 9100 certified (equivalent to AS 9100) since 2012. This standard was created specifically for companies that develop and produce components for the aerospace industry. maxon offers sustainability and stability, combined with  consequent configuration management and traceability of parts. All maxon products rely on standardized designs, manufacturing processes and testing, to ensure maximum repeatability between parts.

Tested according to Aerospace Standards

As UAV applications and use cases grow to be more mature, operational safety of UAVs and corresponding components move into focus. maxon assists drone manufacturer with obtaining operational authorization by providing evidence of compliance to established and harsh aerospace environmental testing standards. Apart from standard maxon qualification testing during the developments, the entire UAV propulsion portfolio went through DO-160 G Environmental Testing. This harsh test campaign includes temperature, vibration, crash safety/shock and humidity tests according to the respective sections in the standard. The maxon drives were subjected to tests similar to the ones required for helicopter components qualification.

Work with the best

For 60 years, maxon has focused on customer-specific solutions in drive system technology. Our brushed and brushless DC motors are used wherever the requirements are high and reliability is of the utmost concern. For more than 20 years, maxon’s drive technology has been driving the Mars rovers on the Red Planet and our engineers use the knowledge they have gained from these and other aerospace projects to further improve serial production components. maxon`s UAV propulsion systems benefit from this extensive experience to design custom drive solutions for application in the most demanding environments.

Frequently asked questions

  • I can’t find a suitable product in the maxon catalog. How shall I proceed?

    Please contact the maxon sales affiliate in your country and provide the following information, so we can assist you:

    • Min/max battery /power supply voltage and battery type
    • Propeller size constraints. If propeller is already fixed, please provide propeller characteristics
    • Peak thrust / torque / speed (and for how long each operating point shall be sustained?)
    • Nominal thrust / torque / speed (continuous)
    • Environmental requirements 
  • What is the advantage of a closed loop ESC?

    The motor speed is controlled and always guaranteed, where as in an open loop ESC the increased motor temperature decreases the speed over time. 

  • Can I use the maxon UAV-ESC with third party motors and propellers?

    While this is theoretically possible, the ESC parameters are defined for the maxon portfolio and do not necessarily work with all third party components. The application note provides first guidance. To get the best performance, the parameters would need to be evaluated at maxon.

  • How frequently does the system need maintenance?

    The ESC and the UAV motor are designed to be maintenance free. maxon designed the motor in such a way that the bearings last for the entire service life of the motor. On lab condition and tests maxon reached 2000 hours continuous operation and additional 1000 hours with a cycle load profile with the same motor (and propeller).

  • Are the system designed to perform in demanding environments?

    Yes. The motor is designed for high environmental protection (e.g. use of shielded bearings), the openings are reduced to a minimum to still achieve the intended performance level. The impact of sand and dust can therefore be minimized. Salt fog on the other hand might impose a challenge on a different level.
    The ESC is designed to have protection class similar to IP 54 (not applicable for product samples). Qualification still in process.

  • What is the IP rating of the maxon UAV portfolio?

    We have not tested our motor according to IP standards and it would therefore not be appropriate to specify an IP rating number. The aim was to develop a motor with a closed overall mechanical design and optimized air circulation. Several iterations were carried out to find the optimal compromise between heat dissipation for high performance and closed design for environmental protection.
