Since the 6 volts will spin the motor very slowly (if at all) the motor (which, while spinning, acts as a generator) doesn't produce enough back-voltage to limit the current, essentially a dead short.
Jul 27, 2023 at 9:37 comment added hdhondt Just remember that, with most equipment, changing the voltage is not a good idea. Increasing the voltage (say, plugging 110V equipment into a 220V socket) may be destructive. Lowering the voltage may cause erratic or faulty behaviour. That said, a lot of low-power equipment like plug-packs will happily work from 100 to 240V.
