Eppo is very important to be unmanned drones motor power system the dynamic system of unmanned aerial vehicle (uav), there are usually two kinds of motor and internal combustion engine, which is given priority to with motor. The electric power system mainly consists of motor, electrical modulation (Control of motor speed), propeller, and battery. Power system matches between the parts, power system and the machine whether match, directly affect the efficiency of the whole machine, the stability, plant protection unmanned aerial vehicle (uav) motor, so the power system is very important.
unmanned aerial vehicle (uav) motor mainly brushless motor, a motor seat fixed on the rack arm, a fixed screw, through the downward thrust produced by the rotation. Different size, load of the frame, need to cooperate with different specifications, power of motor, the motor is not to say that the bigger the better, the efficiency is king.
single motor doesn't work, need to cooperate with electricity, which is used to control the motor speed. Like motor, brushless motor, different load of power system needs together with the different specifications of the tone, though I do not have too big electric call big images, but electrically controlled, nature also heavy, nature would not improve efficiency.
the propeller is the parts directly generate thrust, also is the pursuit of efficiency as the first purpose. Matching of the motor, electric harmonic propeller is tie-in, can under the same thrust consumes less power, so it can extend the battery life of unmanned aerial vehicle (uav). The propeller is both positive and negative direction. Because the motor driven screw rotation, unmanned aerial vehicle (uav) power system, itself will produce a negative torque, would result in a frame of reverse rotation. By a motor is rotating, a reverse rotation, can cancel each other out the reverse torsion, corresponding to the direction of the propeller is the opposite.
now uavs batteries are mainly composed of lithium polymer batteries, characterized by high energy density, light weight, high resistance to electric current value, and so on, these features are more suitable for unmanned aerial vehicle (uav). Phones are some use lithium polymer battery, but the ability to charge and discharge far less unmanned aerial vehicle (uav) these batteries (Theoretical monolithic batteries discharge capacity of more than 400 a)。 And because these batteries used in the dynamic system of unmanned aerial vehicle (uav), so also can be called & other; Power battery & throughout; 。
