But b4 we go futher its seem you friend from the german social media has run into a snag in his post about ecalc and maxons formulas while promoting his own mini calculator on the American forum with another eggheaded that reads and pays close attention to what's said. I have to admit its good Scheiße

Hi, using an e-flight calculator, i recommend to compare the calculated resuls with a reliable source with real measured data including real measured motor efficiencies. This may provides a real insight into the expected accuracies. For instance, a Leopard LC8072-10T (175Kv). Calculations in an e-flight calculators are based on simple math models, representing the steady state behaviour of an BLDC e-flight drive train. Propeller models used in an e-flight calculator somtimes very inaccurate. An e-flight calculator calculates (only a prediction ) an order of magnitude of the needed parameters motor current, motor efficiency and so on in a range of around +/- 30 % worst case. Reaching an overall calculated accuray of +/- 10 % is somtime more a wish than reality. This also applies to my Tiny MotCalc and MotCalc V9.0. Calculated motor efficiencies higher than 90 % using BLDC motors from the recreational sector, mostly cannot be reached in practice, that would be rather a domain of large bldc-motors used e.g. in electric-cars. https://www.reisenauer.de/aid-2043-L...elle-12mm.html Micha |
