TMotor U5 Power U-Type High Efficiency UAV Motor (KV400)

About T-MOTOR U5 Power Type UAV Motor KV400

T-Motor U5 v2 Power series 400kv Brushless Motor - Recommended 6s and 14-16 inch props and Flame 60A ESC Water and dust resistant, designed for maximum reliability and long life. U-series motors are tested to military standards and offer smooth, quiet running with high efficiency.The U5 comes with a special design to ensure swift airflow. Motor cools 2.5 times faster than others. Six holes beveling upward sparkles motor with waterproof and sand-resistant features.Offers high-quality varnished wire. An imported Oxygen-free copper coil that can tolerate a temperature of 180 °C is employed to enhance short circuit resistance.

U5 Highlights:

Unique Side Hole 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 loosiness of circlip.
High-Quality Varnished Wired：imported, oxygen-free copper coil which can tolerate temperature of 180C is 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 lose while improving the utilization. Advanced 0.2mm silicon steel sheet reduces heat and eddy, thus improving efficiency.
Larger Bearing – Lower Noise：Adoption of imported German bearing prolongs the service life to over 1600 hours under trouble-free operation. German bearing enables motor run more smoothly and longer with lower noise.
Max. thrust ：2.85kg
MTBF：About 1600hours
Features：Industrial Grade, Waterproof, dustproof, low noise, large bearings
