Introduction to common terms of drones and batteries

by:Vglory      2021-04-11
General term for drones and batteries. Tattu battery term explanation: Ampere: Standard current unit. In a circuit with a resistance of 1 ohm, the current that appears from a pressure of 1 volt. Battery Elimination Circuit (BEC): A circuit that makes the battery-operated motor also power the receiver and servo power. This is usually built into the ESC. Brush motor: A traditional motor in which brushes contact the rotor and stator. The brushes mainly present the current that makes the motor rotate correctly. Brushless motor: The type of motor used for RC electric aircraft. Brushless motors are much more powerful than traditional brush motors and are often used in electric stunt aircraft. They can be pioneers, or they can surpass engines. Current: The flow of electrical energy. In ampere capacity: Measure the time required to extract a specified current from the battery. Its unit of measurement is ampere hour (Ah), or more commonly the size of an electric flight device, namely ampere hour (mAh). Electronic Speed u200bu200bController (ESC): Controls the current of the motor and the speed factor of the motor. Usually they have built-in BEC. There are two important types-brushless and brush. Horsepower (HP): A measure of work efficiency. Lift 33,000 pounds per minute, or 550 pounds per second. Exactly 746 watts of electricity equals 1 horsepower. inrunner: Just like a standard ferrite motor. They run in a motor. Libao: Lithium-ion polymer battery. These are the most modern aircraft batteries. They provide tremendous power for their scale, especially when used with brushless motors. MAh: The unit of measurement for the total capacity of the battery. The larger the number, the more energy the battery can store. Generally speaking, under a certain load, the battery lasts longer. Nickel-cadmium: an abbreviation for nickel-cadmium. They are rechargeable battery cells used in radio control equipment and electric motor batteries. With the takeover of NiMH and li-po, the use of NiCD is becoming less and less. Ni-MH battery: Ni-MH battery is the abbreviation of Ni-MH battery, it is the successor of Ni-MH battery, with better performance, and the capacity is three times that of the same size battery. Another type of brushless motor whose shell or inside rotates with the shaft. The extra inertia presents more torque, so what is superfluous is a more powerful punch, with fewer gears. Power: Regarding the electric model, this is the product of voltage and ampere, in watts. RPM: The number of times an object is completely rotated (360 degrees) in one minute. Voltage: When applied to a conductor, the unit of voltage in which current appears in the conductor. Watt: When two currents are in the same phase, the power required to maintain one ampere of current under a pressure of one volt. 1 horsepower is equal to 746 watts. Watt is the product of volts and amperes. The power meter is a convenient device to check the operation status of the aircraft's electrical system. What is the discharge rate of the battery? The capacity of each battery is a certain amount in a certain period of time. Compared with the conventional discharge, the discharge rate of the battery is several times that of the conventional discharge. Under normal circumstances, it is necessary to test the discharge performance of the battery under different constant current conditions. How to evaluate the battery multiplier (C)? When the discharge capacity is greater than 85% of the 1C capacity of the cell, the discharge rate of the cell is considered to be N times. For example: a 2000mAh battery, when discharging with 2000mA battery, the discharge time is 60min, if discharging with 60000mA, the discharge time is 1.7min, we think the discharge rate of the battery is 30 times that of 30C. Average voltage (V) u003d discharge capacity (Wh) u0026 pide; discharge current (A) median voltage (V): it can be understood as the voltage corresponding to 1/2 of the total discharge time. The intermediate voltage can also be referred to as the discharge plateau. The discharge platform is related to the discharge rate (current) of the battery. The higher the discharge rate, the lower the voltage of the discharge platform. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
