Re: What motor? [TANKS]

Note that current is proportional to voltage, but power is proportional to the square of the voltage, so doubling the voltage quadruples the power.  The limiting factor is the amount of heat produced, which is related to the current.  The motor's rated voltage is the design level for continuous running without damaging it - you can go higher, but would be well advised to provide active cooling and/or reduce the duty cycle.

Actually, Power is proportional to the square of current... I^2 x R = P  which is why power companies use transformers to jack up the voltage to tens of thousands of volts before sending it out over long distances to keep from losing energy in the form of heat (power).  Raise voltage, current goes down, => I^2R goes down => less heat (power wasted)
