With the growing popularity of remote-controlled (RC) models, brushless motors (BLDC Motors) are widely used due to their high efficiency, high power density, and long lifespan. However, many beginners and enthusiasts often ask: Can RC Model BLDC Motors be waterproof? This article will explain the waterproof capabilities of brushless motors…
In the world of remote-controlled (RC) models and drones, motors are core components that directly affect performance, flight or driving stability, and battery life. Although both RC models and drones use electric motors, there are significant differences in design, performance parameters, and application scenarios. This article will explain the key…
In the design and operation of underwater unmanned vehicles (UUVs), the propulsion system is a critical module that directly affects speed, endurance, and reliability. In modern UUV propulsion systems, brushless DC motors (BLDC motors) have become the mainstream choice. Understanding and selecting the right motor parameters is essential for optimizing…
In underwater robots, underwater thrusters, and unmanned underwater vehicles, motor bearings are among the most critical yet failure-prone components. Many users notice that bearings in underwater thruster motors fail much faster than those in conventional motors, often developing noise, vibration, or seizure after relatively short operating periods. So why do…
During FPV drone flights, many pilots notice a sharp, high-pitched squealing sound coming from the motors, especially at low throttle or during smooth cruising. This sound can be annoying and often raises concerns about motor quality or potential failure. In reality, FPV motor squealing does not always indicate a defect.…
With drones increasingly used in aerial photography, surveying, inspection, and emergency response, operating drones in cold environments has become a common requirement. Many pilots notice that in low temperatures, drones experience shorter flight times, reduced responsiveness, and weaker power output. A key reason behind this is the decline in motor…
Coastal drone photography offers stunning visuals and unique perspectives, making it popular among hobbyists and commercial pilots alike. However, many users overlook a critical issue: the highly corrosive marine environment. Salt spray, moisture, and high humidity can severely damage drones over time—especially the motors. So, how can drones be protected…
In RC car upgrades and performance tuning, brushless motors have become the standard choice. Compared with brushed motors, brushless systems offer higher efficiency and longer service life—but they also require more precise parameter settings. Many drivers notice that even with the same motor and ESC, changes in settings can dramatically…
During the flight of RC fixed-wing airplanes or electric gliders, many pilots experience problems such as difficult takeoff, weak climb performance, sudden altitude loss at low speed, or even complete stalls. Most people first suspect the battery, propeller, or piloting skills. However, in many cases, an incorrectly chosen motor KV…
With the rapid development of underwater robots, unmanned underwater vehicles, and deep-sea exploration equipment, high-performance propulsion systems have become a critical focus. Underwater propulsion systems place higher demands on motors than terrestrial applications, including efficiency, long service life, corrosion resistance, and reliable sealing. Among available drive solutions, brushless motors (BLDC…
