Oranges ? I think I must be eating something a little more potent.

The FIRST line of the white paper reveals the clue....

"The motor power output (speed times torque) is determined by the
power supply voltage and the motor's inductance. The motor's output
power is proportional to the power supply voltage divided by the
square root of the motor inductance."

Inductors is where my ignorance comes in...
