Actually, a motor is not a "constant power" device. The power rating for motors is the limit, not a constant.

Inductive reactance aside (to oversimplify to remain in the scope of this discussion), consider a motor like a static resistor. Amps=Volts/Resistance. So, more V = more A for a given R.

Yes, there is a limit to how much power any motor can dissipate. If exceeded, the result is melted coils.
