Custom FPV Drone Motor Solutions Available
We provide professional OEM & ODM customization services for FPV drone brushless motors.We can customize motor specifications according to your flight demands: KV value tuning, stator size optimization, winding scheme adjustment, shaft structure, mounting hole layout, surface treatment, logo marking and cable configuration. Our engineering team supports design verification, prototype sample testing and mass production. Adopting advanced international production equipment, we strictly control processing precision to guarantee stable motor performance, high efficiency and consistent quality.Whether you need lightweight motors for FPV freestyle & racing, high-torque motors for industrial heavy-lift frames, or long-endurance optimized motors for beyond visual line-of-sight missions, we deliver one-stop customized motor solutions.
Important Notes & Safety Guidelines
Do NOT operate beyond rated power, avoid over‑load conditions.
Check propeller mounting tightness before every flight. Keep away from rotating parts.
Use proper‑length mounting screws; over‑long screws will damage internal coils.
Do not pull or lift motor by power cables or shaft.
Do not disassemble the motor; disassembly voids product warranty.
Storage condition:‑20℃~60℃, 10‑90%RH non‑condensing, storage period ≤6 months.
Bearing maintenance or replacement is required after 300 hours cumulative operation.

Strict quality control runs through every production stage, balancing high efficiency and consistent stable quality. Backed by leading manufacturing strength, Xpert reliably handles all types of batch customization orders.
FAQ
1. Can this motor run continuously at 100% throttle full‑power?
100% full‑power is peak instantaneous power. Sustained full‑throttle operation will lead to sharp temperature rise and shorten service life. We suggest avoiding long‑time full‑power work.
2. Are test reports and inspection records available for bulk orders?
Batch‑wise inspection records can be provided upon request for bulk orders. Thrust test data in datasheet is based on QF 1507 three‑blade propeller lab test.
3. Can I cut the motor power cable shorter on‑site?
You may cut the cable, but you must strip and tin the wire ends before soldering. Direct soldering on varnished wire without tinning will cause poor connection.
4. What is the maximum allowable operating temperature for the motor bearing?
The upper limit of bearing temperature is 100℃. Continuous operation above 100 ℃ will accelerate bearing wear, generate noise and shorten service life.
5. Why does internal resistance value change in different ambient temperatures?
Winding resistance will shift with temperature changes. The 45mΩ ±3% value is tested under standard room temperature. Large‑batch deviation caused by temperature fluctuation needs re‑confirmation between both parties.
