Torque and RPM Graph for Castle Creation products ?

Looks to me like the torque is left to right on the graph.Which means the more load they put it under the lower the efficiency went.Which is to be expected. Looks like it reached about 34 oz/in of torque,with no rpm fall off.But it was down to 50% efficiency.Now if we only had the same graph for every other motor we could interpret some results.

Green is RPM, red is efficiency, and the graph is for Torque -- the graph goes from 0 oz/in to 35 oz/in from left to right.

So, to find RPM and efficiency at a given torque, find the torque on the bottom, and follow the line up for RPM and efficiency at that torque.

Please note that this graph is for 16.0V only.

No, the efficiency is the red line -- so at 34oz/in of torque, it was still at 84% efficiency.

Green is RPM, so the RPM was down to around 32500RPM

The 50% efficiency point is at around 240oz/in. (if my memory is correct)

This graph is a little misleading because at the right most point the motor is only outputting 1.21 horsepower. But we use this type of graph to do comparison testing between motors to determine if the motor iron is saturating early. A nice flat graph from left to right is the goal.
