For beginners entering the world of FPV drones, motor selection is often overlooked compared with frames or video systems. In reality, motors play a critical role in flight stability, control feel, and the difficulty of tuning. Choosing the right motor helps beginners build confidence quickly, while a poor choice can…
In daily FPV (freestyle or racing drone) flying, crashes are almost unavoidable. After a few hard impacts, many pilots notice a common issue: the motor still spins, but the shaft looks slightly bent. This raises a frequent question—can an FPV motor still be used if the shaft is bent, and…
Drone endurance directly affects operational efficiency and mission completion in photography, inspections, and agricultural applications. Battery capacity, flight load, and weather conditions all influence flight time, while the propulsion system, as the core energy-consuming component, significantly impacts energy efficiency. Among various ways to extend drone endurance, whether using a high-efficiency…
When drones are used outdoors for photography, inspection, or agricultural spraying, they often encounter rain, mist, or humid environments. In such situations, drone motors may get wet. If not treated promptly, water entering the motor can cause short circuits, burning, or damage to the control system. Therefore, knowing how to…
Brushless motors are widely used in RC car power systems due to their high efficiency, long service life, and low maintenance requirements. However, under conditions of high speed, heavy loads, and complex driving environments, brushless motors can still experience various failures. If these issues are not identified and resolved in…
In applications such as RC aircraft, RC cars, and unmanned model boats, brushless motors have become the mainstream power solution. Compared with traditional brushed motors, high-efficiency brushless motors offer clear advantages in power density, energy consumption, and operational stability. Their performance differences are determined not only by design parameters but…
In underwater thrusters, marine robots, and offshore equipment, brushless motors are widely used due to their high efficiency and long service life. However, compared with freshwater or air environments, seawater presents a much more aggressive corrosive challenge to brushless motors. Without adequate protection, corrosion can degrade performance and significantly increase…
In underwater robots, autonomous underwater vehicles, and various subsea operating equipment, the underwater thruster is the core component that provides propulsion. Once insufficient thrust occurs, it not only affects maneuverability but may also lead to unstable positioning, increased energy consumption, or even mission failure. Among the many possible causes, electric…
FPV drone motors are the core components that drive flight, and the motor magnets, which generate the magnetic field, directly impact thrust, efficiency, and durability. As FPV flight speeds and power demands increase, the magnet grade and its stability under high temperatures have become critical factors affecting flight control performance…
FPV racing drones, also known as quadcopters for speed racing, are renowned for their high velocity, agility, and extreme maneuverability. The motor, as the core power component of a racing drone, directly determines flight speed, acceleration, and control responsiveness. In high-speed flight scenarios, high KV (RPM per volt) motors are…
