Hello everybody,
I'm buying components for my next engineering project and I stumble upon a spreadsheet called Team Run Amok Spinner Weapon Excel Spreadsheet which is a pretty interesting file for people like me that uses brushless motors for projects. The biggest issue with this kind of motors is that there's usually not much information regarding the torque constant in sites like hobbyking.
This is where this excel file is pretty cool, it has a stall torque estimator and it also shows some pretty useful graphics.
My problem is I'm not understanding the equations from the file.
According to the spreadsheet the stall torque is equal to:
((1352/Kv) * (Voltage/Resistance)) /141,69
Now I understand that the stall torque is equal to Kt * (Istall – Ino_load) but I can't find out the origin of the constants in the excel equation.
And I have tested this with quality motors that I have all the specs and the results are pretty much the same.
thanks in advance.
