When you are sourcing motors for a new unmanned aircraft project, the first conversation usually starts with voltage and propeller size. Those two factors determine everything else about the build. A 6S system swinging 14-inch props needs a completely different BLDC electric motor supplier than a 12S rig running 30-inch carbon fiber blades. Looking at the catalog from Brushless Inc., the range is organized around these real-world constraints rather than abstract marketing categories. The heavy lift series starts at 100KV for the biggest platforms, with the 130KV and 170KV models covering the 22 to 29-inch propeller range on 12S systems. For medium-lift applications, the 250KV and 320KV variants handle 20 to 24-inch props on 6S or 12S, while the 400KV model is designed for 14 to 16-inch propellers on 6S. Each listing includes specific details like recommended propeller sizes and voltage ratings, which removes guesswork during the design phase.

The multirotor side of the lineup focuses on disc-type motors built for stability and quick throttle response. The 300KV model features a stator diameter of 52mm with a 10mm thickness, paired with a patented stepped and knurled mounting design that prevents loosening during high-vibration operations. This becomes relevant when the airframe carries expensive sensor packages where even minor instability degrades data quality. The 340KV option uses the same 52mm stator diameter but with an 8mm thickness, offering different torque characteristics for lighter platforms. Maximum continuous power ratings across this series range from 250W on the 400KV model up to 560W on the 740KV variant, giving builders multiple options within the same physical mounting footprint. For applications requiring even higher responsiveness, the 320KV and 380KV models provide 375W to 450W continuous power with the same disc-type construction optimized for rapid throttle changes during autonomous flight.

Fixed-wing applications demand motors optimized for sustained cruise efficiency rather than instant thrust. The fixed-wing series from this BLDC electric motor supplier includes the 1500KV motor with a 3mm shaft and high-performance tile magnets for lightweight 2-3S gliders and small surveillance platforms. The 980KV model uses a 12N14P high-torque design for 3-4S aircraft requiring efficient cruise with occasional climb power. For larger fixed-wing platforms, the 480KV motor runs on 5-6S with NSK precision bearings and a 6mm shaft, designed for jitter-free operation at higher speeds. The 570KV variant incorporates a hollow shaft end cap that increases heat dissipation surface area, addressing thermal buildup during long-endurance flights where motors run continuously for an hour or more. Shaft diameters range from 3mm to 6mm across the series, accommodating different propeller hub sizes and mounting requirements.

Beyond the specific motor models, the engineering details visible across the catalog indicate manufacturing consistency. Multiple models use precision bearings from manufacturers like NSK, which affects long-term reliability and maintenance intervals. The 400KV heavy lift motor lists a maximum continuous power of 700W with a recommended takeoff weight per arm of 1200g, giving engineers clear margins for payload calculations. The 300KV multirotor motor includes specific details about the stepped and knurled mounting interface, addressing a known pain point in the industry. For OEMs building drones for inspection, delivery, or survey applications, having access to a BLDC electric motor supplier that provides this level of technical specificity across a range from 100KV to 1500KV means fewer prototypes and faster time to market. Whether the requirement is a 12S heavy lift motor for agricultural spraying or a 3S fixed-wing motor for pipeline patrol, the catalog provides documented specifications that support engineering decisions without guesswork.
