A continiously variable transmission is a great idea.

The motors they give us can put out around a half a HP, if you keep them in the center of their RPM range. Look that the speed and torque VS current curves for the drill motors and the Chalupas.

problem is we start off at zero - the motors put out very little power at 0 RPMs.

I like this idea you have - I think it could be even better if you could find a way to keep the motors spinning at their optimal power output (midrange of their speed curve) and then vary the transmission ratio as commanded by the driver for speed. in other words, you would have a closed loop sensing the motor speed, and holding it constant through the Victors output, and the driver would vary the transmission ratio, not the motor speed. the performace (acceleration, pushing power, and top speed) of a setup like this would be phenomenal!

Im looking forward to seeing your published ideas on this.
