Maximum power, minimum size: This is how you optimize your drone drives with ATEK planetary gearboxes.
What are the main advantages of planetary gearboxes in drone drives?
Planetary gearboxes offer a high torque density, which means they can deliver a lot of power in a compact size and low weight. This is crucial for the payload capacity, flight time, and maneuverability of drones. Their high efficiency also contributes to performance enhancement.
What role does material selection play in torque strong planetary gearboxes for drones?
Material selection is critical for the optimal ratio of weight to strength. Often, aviation aluminum is used for housings to save weight, while hardened steel is used for gears to ensure the necessary robustness for high torques. Specialty materials like ceramics or plastics are used for special requirements.
Can planetary gearboxes be adapted to specific drone applications?
Yes, companies like ATEK Drive Solutions specialize in customized drive solutions, even in small series. This includes the customization of gear ratios, shaft configurations, materials, and lubricants, to optimize the gearboxes for extreme temperature ranges, special load profiles, or installation spaces.
How does gearbox design influence the noise and vibration of a drone?
A well-thought-out gearbox design with precision-engineered gears, backlash-free designs (e.g. LZ variants from Maxon) and high-quality materials can significantly reduce noise and vibrations. This is particularly important for operations in noise-sensitive environments or to protect sensitive sensors onboard the drone.
What rated torques and gear ratios are typical for drone planetary gearboxes?
The values vary widely depending on drone size and application. For example, Nanotec’s GP series offers rated torques of up to 47.85 Nm. Multi-stage planetary gearboxes can achieve gear ratios of over 200:1 to deliver very high torques for heavy-duty drones. In the micro range, 6mm gearboxes can already generate torques around 20 mNm at high gear ratios (e.g., 1:700).
How important is the system integration of gearbox, motor, and control in drones?
System integration is very important for overall performance. An optimal coordination between gearbox, motor, and electronic speed controller (ESC), such as the factory calibration of Maxon ESCs to their motors, is necessary to achieve high efficiencies (over 90% possible with FOC) and precise control of the drone drive.
What role does thermal management play in high-performance drone gearboxes?
Thermal management is critical for reliability and lifespan, as high torques and continuous loads can generate heat. Effective measures such as special lubricants for extended temperature ranges or constructive cooling elements are important, especially when gearboxes continuously deliver torques over 40 Nm .
Are there online tools to select and configure planetary gearboxes for drones?
Yes, many manufacturers, including ATEK Drive Solutions with its online product configurator, offer such tools. They enable engineers to configure gearbox solutions based on specific requirements, simplifying the selection process and can significantly reduce development times, partly by up to 30%.
