サインインして注文 →Provide high thrust and efficiency for large drones and sport aircraft. The QX-Motor QF3748 1200KV motor is designed to work with 12‑13″ propellers on 4‑6S batteries. Power up to 2200 W and a reinforced 37x48 mm stator guarantee high performance. The hollow shaft simplifies installation and wiring. Choose a reliable motor for the most demanding projects.
High power 2200 W. Provides lifting of heavy drones and energetic flight of aircraft.
Large stator 37x48 mm. Generates high torque for efficient rotation of large propellers.
Hollow shaft with a diameter of 5 mm. Convenient for hidden wiring and easy installation.
Wide voltage range 4‑6S LiPo. Flexibility in choosing a battery for a specific task.
Recommended propellers are 12x6 (6S) and 13x5.5 (5S). Optimal propellers for maximum traction.
QX-Motor QF3748 is a brushless motor with an external rotor (Outrunner). 12 poles and 14 magnets (12N14P) configuration ensures smooth running and high torque. The stator with a diameter of 37 mm and a height of 48 mm is designed for long-term loads. The internal winding resistance is 22 mOhm, and the no-load current is 1.5 A at 10 V, which indicates good efficiency. The hollow shaft with a diameter of 5 mm allows the wires to pass inside, protecting them from damage.
The motor is secured with four M3 screws with a pitch of 25 mm. With a weight of 210g and compact dimensions (49x65mm), it easily integrates into frames for 7‑10‑inch propellers. It is recommended to use 60-80 Amp controllers with 6S support.
The QX-Motor QF3748 1200KV engine is ideal for powerful quadcopters with a diagonal of 7‑10 inches, for heavy cargo drones, as well as for large aerobatic and sports aircraft (wing span 1.2‑1.5 m). High power and torque allow it to be used in vertical take-off (VTOL) systems.
