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…
Noise generation during drone flight is unavoidable, but noise levels affect not only the flight experience, but also video quality, privacy concerns, and regulatory compliance. In urban aerial photography, inspections, and other low-altitude operations, reducing drone noise has become a key consideration. Drone noise mainly comes from propeller airflow and…
Motor burnout is a common issue encountered by many drone pilots. Whether used in aerial photography drones or FPV racing drones, once a motor overheats or fails, it not only affects flight safety but also leads to increased maintenance and replacement costs. Many users simply attribute the problem to poor…
In the overall design of an RC aircraft, the power system plays a decisive role in flight performance and user experience. A well-configured power system directly affects takeoff efficiency, climb performance, endurance, and overall flight stability, while also influencing component lifespan. Motors, propellers, and electronic speed controllers (ESCs) are the…
In RC cars, boats, aircraft, and other model systems, the motor is the core component of the powertrain. During extended operation or under high loads, motor temperature naturally rises. However, excessive heat can lead to performance degradation, reduced motor lifespan, and even winding damage. Therefore, mastering effective cooling techniques and…
With the widespread application of underwater robots, ROVs, submersible thrusters, and marine engineering equipment, underwater-operation-grade brushless motors have become core power units. Compared with conventional industrial motors, these motors must not only deliver efficient drive performance but also withstand harsh environments characterized by high humidity, high pressure, and strong corrosion.…
Submersible thrusters are widely used in unmanned surface vessels, ROVs, underwater robots, and various marine engineering systems. Their core component—the motor—operates for long periods in harsh environments characterized by high humidity, high pressure, and continuous water flow. Once water ingress occurs, propulsion efficiency may decline, and more serious consequences such…
