TMotor U7 V2.0 Power Type UAV Motor (KV280 / KV420 / KV490)

About T-MOTOR U7 V2.0 Power Type UAV Motor KV490

T-Motor U7 v2 U series motors from Tiger motors is designed for lifting DSLR cameras. Using U7 V2.0 motors you can lift quadcopter upto 7kg. These motors are best if you are planning to build a Quadcopter or Hexacopter for a professional photography multirotor.

U7-V2.0 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 ：4.64kg
MTBF：1600hours
Features：Industrial Grade, Waterproof, dustproof, low noise, large bearings
