VSD 5315 380KV Drone Motor

 

This 5315 brushless motor adopts an outer rotor structure, equipped with a high-efficiency 12N14P magnetic steel combination and a large-size iron core (φ53×15mm), with a stable magnetic circuit design and excellent current response capability. Its KV value is 380, specially optimized to support 6S to 12S battery platforms, with a peak power of up to 4257W and a current limit of 101.88A, making it an ideal power core for high-thrust UAV systems.

 

Our 5315 motor 380KV has a built-in high-temperature H-class insulation coil and uses a low-impedance winding to ensure that the motor can still maintain low-temperature operation and high-efficiency output under high load conditions. Equipped with 13AWG high-temperature resistant silicone wire (800mm), it is easy to install and layout. The weight of the motor is only 310±3g (including wire), taking into account both performance and lightweight.

The motor temperature is the temperature at which the Motor runs for 3-10 seconds under 100% throttle (the above data is measured by our testing platform, and for reference only, it cannot be directly compared horizontally with data from non our testing platform)

 

These four propeller configurations fully demonstrate the wide adaptability and thrust potential of the 5315 motor 380KV. Whether it is an endurance mission or an extreme load, a suitable combination of ESC and propeller blades can be found.

 

Among the 5315 outer rotor brushless motors of similar specifications, our 5315 motor 380KV performs particularly well in key performance indicators. The following is a comparative analysis of its core advantages in four aspects: thrust output, unit power efficiency, temperature rise control and adaptation range.

 

1. Stronger thrust and more thorough power release

When using the GF1308-3 three-blade propeller + 12S platform, the 5315 motor can output a maximum thrust of 9034g, corresponding to a maximum power of 4257.4W.

 

Compared with some mainstream 5315 motors on the market (such as a certain brand with a nominal power of less than 3500W), this motor has a stronger power release capability and is especially suitable for high-load scenarios such as cargo flight and spraying platforms.

 

2. Excellent unit efficiency, especially in the low and medium throttle range

When the HQ15x7-3 propellers are used with the 6S and 10S platforms, the efficiency reaches 9.23g/W and 9.05g/W respectively at 30% throttle, which is much higher than the industry average (about 7.5g/W).

 

Efficiency performance in the medium and low speed stages means longer flight time and better battery utilization.

 

3. Stable temperature rise control, suitable for continuous operation

It is measured that under long-term operation at high load (100A current), the maximum temperature of the motor is 118°C, which is still within the H-level insulation range (≤180°C).

 

The high-temperature enameled wire + large-area iron core design effectively delays heat accumulation and is suitable for medium to high-intensity continuous flight missions.

 

4. Wider voltage and propeller adaptation range

6S ~ 12S voltage range supports a variety of flight control and ESC platforms

 

Adapt to propellers with different aerodynamic characteristics such as HQ15x7-3 and GF1308-3, with strong compatibility

 

Customized KV value, cable length and installation interface can be provided according to customer needs
