That calculator was written by Andrew Schreiber¹, and was based on an early version (now superseded) of the Drivetrain Acceleration Model².

The model was updated a few days later to correct a small error and include the effects of reduced motor voltage caused by circuit resistance³. Andrew's calculator has not yet been updated to reflect the updated model.

Full C source code² is provided for the Model. All you need is a C compiler and you can change the parameters, compile, and run it. Compiling and running takes less than 2 seconds. The output is a CSV file which will open directly in Excel if you set file associations. Columns in the CSV file include time, distance, speed, acceleration, motor current, and motor voltage.
