Agricultural drones, for instance, benefit from the precision of these drives to maintain exact flight paths. As an industry standard, such brushless motors provide over 30% higher efficiency, significantly longer lifespan, and reduced maintenance effort – all critical factors, for example, for delivery drones. Our servo motors exhibit similar advantages.
The brushless design of these high-performance motors significantly reduces friction and heat generation, leading to an impressive lifespan of over 10,000 hours. At the same time, it allows for extremely precise control, which is essential for complex flight maneuvers, such as those required for filming. A high-speed brushless motor for drone drives is often the first choice here. See also mini gearboxes..
Importance of brushless motors in modern drones

For example, surveying drones can transport heavy laser scanners thanks to these powerful drive systems while maintaining flight stability of ±5 cm.
Why brushless motors dominate
The dominance of brushless motors for drone drives is due to their higher efficiency, which can lead to an extension of flight time by 15-20%, as well as their lower noise emission. This is particularly advantageous for operations in urban areas, such as facade inspections (e.g., with the T-Motor U15XXL).Advantages of brushless motors for drone drives
Brushless motors achieve an impressive efficiency of 85-90%, directly resulting in longer flight times and the ability to carry higher payloads (e.g., an additional 0.5 kg). A high-speed brushless motor for drone drives is often the key. Our lightweight gearboxes can additionally support these advantages.
- High efficiency of 85-90%
- Enables longer flight times
- Carries higher payloads
- Offers a significantly longer lifespan (>10,000 hours)
- Requires minimal maintenance due to the absence of brush wear
- Ensures precise control and quick response times.
An integral system approach that includes the motor, electronic speed controller (ESC), and propeller is crucial for optimizing thrust and energy efficiency. Perfectly tuned systems, like in the Maxon/ASIO drone, can enhance overall efficiency by 10-15%, which can mean an additional range of 10 km for delivery drones. The basis for this is always a properly selected high-speed brushless motor for drone drives.
Efficiency and performance
The superior efficiency achieved by eliminating brush friction in a brushless motor can extend flight time by more than 20%. Models like the EMAX ECOII 2807 demonstrate this with an energy conversion of over 85%.
Durability and maintenance
The minimal maintenance effort caused by the absence of brush wear in brushless drone motors, results in a significant reduction of operating costs. Their lifespan often exceeds 10,000 hours, while brushed motors typically reach only 1,000 to 2,000 hours.
Precision and control
The precise control of speed and direction, as well as the quick response times enabled by a high-speed brushless motor for drone drives , are essential for the stability and agility of drones, especially for FPV drones that reach speeds of over 150 km/h. The KV number (e.g., 1700KV) is a relevant parameter.Selecting the right brushless motor for drones
When selecting the right brushless motors for drones is the KV value (revolutions per minute per volt) a central factor. A high KV value is suitable for small, agile drones that often high-speed motors and small propellers, while a low KV value is ideal for larger drones with big propellers and high torque demands. FPV drones typically use motors with 2400-2700KV, while heavy-lift drones use those with 100-300KV.
The size and weight of the motor directly affect the flight time and payload capacity of the drone. Ideally, the weight of the drone motors should account for less than 20-25% of the total takeoff weight (e.g., below 250g for a 1kg heavy drone). Equally important is the compatibility of the motor with the electronic speed controller (ESC), especially regarding current load capacity.
KV value and application range
The careful tuning of KV value, operating voltage (e.g., 4S or 6S LiPo batteries), and propeller size is crucial for the performance of the drone drive. A 7-inch long-range drone equipped with a 1300KV motor, a 6S battery, and a 7x4x3 propeller can achieve flight times of over 20 minutes, for example.
Size, weight, and compatibility
When constructing drones, every gram counts. A thrust-to-weight ratio of over 5:1 is desirable; professional applications often aim for 10:1 or higher. The T-Motor F60 Pro IV, for example, weighs just 55g but generates a thrust of 1.6kg, highlighting the power density of modern brushless motors . The ESC must match the maximum current and the number of battery cells.
System level and optimization
The motor, the ESC, and the propeller form an integrated drive system. Their precise tuning is essential to ensure maximum performance and efficiency of the high-speed brushless motors for drone drives . An incorrect configuration can lead to performance losses or even system failures. In certain applications, high-torque planetary gears can contribute to optimization.Technical aspects and design considerations
For drone applications, outrunner motors are generally the better choice, as they provide more torque at lower speeds, making them ideal for direct drives. Inrunner motors, which typically reach high speeds , are less commonly found and may require a gearbox. Most FPV and camera drones rely on outrunner, which are precisely tailored to (e.g., CENPEK A2212).
