Why was U-Power born?


 Why was U-Power born?
 With Multirotors widely used in many fields. There are more requirements for high quality power system focusing on Unparalleled reliability, durability, high power and high efficiency. Further more the working environment of motor is considered. The motor must operate in extreme climate conditions, so the performance must be designed waterproof and dirt resistant. THIS IS WHY U-POWER WAS BORN.        To meet the customer’s rigorous demands we started development of U-Power in 2011. Today, with 18 months of research and development we release (here is u-power logo )for UAV market.
However,there is much more to the story behind the scenes,For instance .our R&D department spent 18 months and work hard to ensure precise of appearance,craftsmen,construction and performance,flawless products are delivered right from the factory and ready for use in your application.


There are two series of U-power for different customer requirement.
Power Series :U3 U5 U7

Power Series :U3 U5 U7 U11 Aerial UAV of Photography,Video,Inspection,security,Surveillance ,scientific,Mapping
Efficience Series :U6 U8  which are focused on Long Flight time.

      We’re here to help! The passion of our innovation starts with our legendary motors. But with the release of our U-Power Series, we’re now focusing efforts on creating the optimal performance packages for UAV and Multi-Copter enthusiasts. Send us your Use Case or specific requirements. We can work with you to strip out the technical complexity and match the optimal motor, combined with the best ESC and Propeller combinations for your unique needs!

Construction
Self-cooling system(Patent protected)
1)The housing has unique cooling holes that while running pump 2.5 times more air through the motor than our MT and MN series.
2Options for two mounting prop method.(patent protected)
3)Abnormal shape shaft design to avoiding loose.
4)By combining the tight outlet cable way of MT and MM series
5)By combining the lightweight and high structure strength we leave the muscle on the inside surface.


 The top Four Advantages of the U-Power construction:
Waterproof
Dirt Resistant
Thermal Dissipation Optimized
Resistant Collision, drop, and pressure, extremely durable

 The top Five Advantages of the U-Power Material:
1.-----Bearing
   This Germany Bearing is three timers bigger than EZO bearing.
Features:----Long life :MTBF(Mean time between failure):160 Hours
        ----Running smooth
        ----silence sounds
2.----Housing Material
Features-----High hardness aluminum front and rear housing is more durable.
      -----CNC Machined hight  aluminum front and rear housing with cooling holes not only pump air through the motor and also waterproof and resistance sand while it runs.
3.----Copper wire
-----Oxygen-free copper wire temperature of 180 degrees is used in winding the motors to enhance resistance to short circuit.
4.---Silicon steel sheet
Features:All the stators of our motor are made with high lever 0.2mm laminations for maximum efficiency and minimum eddy current lose,which is better than the MN and MT series motor. High quality stator plates are epoxy coated on the inner surface to prevent winding shorts
5.------Magnet
   The Magnet is ensured by our rigorous 100% inspection within the tolerance before next process.
