a concept i can't grasp is the meaning of voltage for an electric motor. it seems all the motor needs to operate is a magnetic field which is generated by current. why does the electric motor "care" whether the current is fed to it from a 100V or a 200V battery? Isn't the concept of voltage useful only when talking about whatever delivers the current to the motor, like a battery?
