The rotor of any motor has mass, and can''t speed up instantly. So, whenever you connect your DC motor to a 9V battery, it won''t draw infinite current, and won''t instantly jump to 6000RPM speed. It will however accelerate, and momentarily draw a large current while doing so. All motors are flywheels.
