Yeah, I caught that. I think the idea is important enough that I would have made it explicit. I think explaining how the Speed-Torque curves shift with voltage provides incite that leads to deeper understanding. But... ...this is more of my personal biases showing.
Of course, this was not my presentation. Everyone has different points of view. I am coming off much harsher than I intended. It was a good talk. I may disagree with this or that point but in general it's fine. I shouldn't throw the baby out with bath water.
This is especially true since I gave a talk on Friday in which I told about 30 FIRST mentors that one key to success is to have at least one person on the the team understand the Speed-Torque Curves for motors. If teams go with the information in this Behind The Lines talk, they'll be a lot better off than just using tribal knowledge and tradition to pick motors and ratios.
My criticisms should have been more temperate.
