You can move the variables around via simple algebra and you can see why increasing one variable will decrease another to maintain the equality in the relationship. So in motor terms - if you cut the voltage in half you will make the motor attempt to draw twice the current (and run real hot) because the load (resistance in the windings) has not changed. Think of the simple starter in your car. It's only a mere 12 volts, yet draws hundreds of amps for a short amount of time before you literally cook the windings It's a bit more complicated in AC versus DC motors but hopefully you will understand the concept here.
