In submersible thrusters, the BLDC motor is the core component that directly determines propulsion efficiency, maneuverability, and energy consumption. When selecting a motor, torque is one of the most discussed parameters. High-torque motors are often assumed to be superior, but in practice, choosing the right torque requires balancing performance, efficiency,…
The underwater thruster BLDC motor is a critical component of underwater unmanned vehicles, submersibles, and small marine propulsion systems. Its operating environment is unique, with long-term immersion in water or near-water conditions. During operation, the BLDC motor generates significant heat. Insufficient cooling can lead not only to efficiency loss but…
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…
