We know that the Jaguar controls the speed of a CIM motor very linearly. We also have data on the voltage drop across a resistive load. Could we correspond the voltage drop across the resistive load to the current draw of the CIM motor, and thus the torque of the motor?

In other words, torque is pretty linear.

(I can't seem to find where I got the vic-jag comparative data. It looks like a graph from an Excel spreadsheet.)
