P = I x E is NOT Ohm's law. It is a formula for calculating power. Ohm's law defines resistance, not power.
When you increase the voltage applied to a dc motor, the current does not remain constant. It increases. Motor torque is directly proportional to current.
Now, when you increase the voltage to a dc motor with NO LOAD, it will turn faster. But that is not because it has "more power". It can go faster because there is more voltage to overcome back EMF, back EMF being proportional to speed. But the power does not increase significantly because it is producing no torque, hence it has almost no current and is consuming almost no power.

Today's Featured Article - Ford Part Number Trivia - by Forum Participants. "Replaced by" means the part was superseded. All of my part books date back to 1964 and New Holland have changed some part numbers. They usually put the old Ford part number on the package. I was suppressed when I looked up the part number of the auxiliary drive shaft because for some reason the part number went through a radical change and it lost its "Basic Part Number". Ford part numbers follow the following rules. Most part numbers are in three parts. The middle part is called the
