This design has two spinning wheels, top and bottom. There are two separate FP motors running the wheels.

As of right now, we are running full applied voltage.
When you are running at full voltage, how fast are the wheels spinning? Or, how much current is each motor drawing? This is the data needed to estimate the operating point on the motor curve, so your question can be answered properly.

Also, are your motors properly vented? i.e, are the air vents unblocked?

Without the above answers, my guess would be either:

1) Spinning the belts at that high speed is placing a load on the motors that they cannot continuously sustain, or

2) The motors are not properly vented.
