I think you have that a little incorrect. A motor will draw more current with more voltage. This assumes that the motor wind, gearing, etc is unchanged.

If you increase the voltage, you have to increase the number of motor turns to reduce current.

However, if you want to run higher voltage on the same motor, you could gear down a little. That will reduce the mechanical load on the motor, which reduces the current. So, the higher current generated by the higher voltage is somewhat offset by the reduced mechanical load.
