BPM diagrams with torque versus speed/Ampere

[xango]

Does someone have this diagrams for the 3 versions of the bafang rear drive: 36V/250W, 36V/350W and 36V/500W. Or maybe a link to this diagrams?

There are more than 3 versions (codes) - the table only shows codes 10, 11, 15 and 16.
Torque-per-amp increases by ~ 10% with each code increase.
