Drone electric motor U5 KV400

• Water-resistant & Dust-resistant • Precision Bearing SPECIAL SIDE HOLE DESIGN Special design ensures swift airflow. Motor cools 2.5 times faster than others. Six holes beveling upward sparkles motor with waterproof and sand-resistant features. ABNORMAL SHAFT A special screw is used for stator and rotor installation, avoiding looseness of circlip. HIGH-QUALITY VARNISHED WIRE Imported Oxygen-free copper coil which can tolerate temperature of 180°Cis employed to enhance short circuit resistance. HIGH-STANDARD SILICON STEEL SHEET PRECISION WINDING The precision winding ensures the tightness of coil and slot. It helps reduce the copper loss while improve the utilization. Advanced 0.2mm silicon steel sheet reduces heat and eddy,thus improves the efficiency. LARGER BEARING LOWER NOISE Adoption of imported bearing prolongs the service life to over 1 600 hours under trouble-free operation, bearing enables motor run more smoothly and longer with lower noise.
