  • what do electric motor specs mean?

    Specifically Watts, Volts, and Amps. I know Watts is J/s which is how much energy is being used per time, but I do not know how the volts and amps of a battery play into it. I also know that volts is the difference across the battery terminals and amps is the speed of the current, but how does that effect performance? i.e. if there are 2 motors with the same watts, what does changing the voltage or amperage do?
