Measuring of Copter Motor Power Characteristics

Josef ČASAR, Jiří FISCHER and Vadim STARÝ


The article deals with the measuring of power characteristics of an electric copter motor. The aim is to design and realize the measuring workplace and algorithms, to verify declared parameters and get performance characteristics. The measurement is focused especially on a rotor thrust force. For more effective and accurate measuring, specific operations have been automatized. The whole process can be controlled by either open-source electronic prototyping platform Arduino or National Instruments myRIO device. The mechanic part of measuring workplace is realized by a pendulum with one degree of freedom. The object that was verified in this experiment was the motor 850Kv AC2830-358 with the 10×47 propeller made by 3DRobotics company.
