On-line Power Train Analysis

This is the culmination of the developments made within ThrustXL and MotorXl, and includes updated databases for props and the start of a motor database.

Being an online utility this offers accessable routines and graphs to MAC and Linux users without the need for Microsoft Excel.

This is the most powerful of all the utilities and offers functionality like MotorCalc but using empirical measurements from props. With this it is possible to select a prop, motor and drive voltage and the current, thrust, and RPM will get accurately predicted

This is the most recent development that supercedes both ThrustXL and MotorXl, and includes updated databases.

Being an online utility this offers accessable routines and graphs to MAC and Linux users without the need for Microsoft Excel. Some may use the utility in order to obtain the latest thrust and power constants for their props and use with their Emeter (or similar)

This is probably one of the best, and most complete, suite of motor analysis tools that has ever been written for use in Microsoft Excel

Prop power and thrust constants have been incorporated in a similar manner to that in ThrustXL and MotorXL

I have created an on-line data submission tool for this suite here

MotorXL Ver 1.00 is an accurate motor efficiency and thrust calculator I have written that relies on a huge database of real measurements for an accurate estimation of power from measured RPM, accurate calculation of motor efficiency and thrust from measured current and voltage. This is the combination of both ThrustXl and EffXL
