TMotor U3 Power Type High Efficiency UAV Motor (KV700)

About T-MOTOR U3 Power Type UAV Motor KV700

U3 KV700 motors (from U-series) are aimed for high end UAVs requiring big thrust.
This kind of UAVs are usually for professional aerial photography, filming, delivery service and agriculture applications.Handmade high-temperature enameled wire has excellent fire protection, industrial grade waterproofing, anti-aging and other properties, which greatly extends the service life of the motor. The precision winding ensures the tightness of coil and slot.It helps reduce the copperloss while improve the utilization. Adoption of imported high-quality bearing ，enables motor run more smoothly and longer with lower noise.U3 Power series 700kv - recommended 4s esc and 12 or 13 inch props Water and dust resistant, designed for maximum reliability and long life.

U3 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: 1.8kg
MTBF: about 1600hours
Features: Industrial Grade, Waterproof, dustproof, low noise, large bearings
