It's not what kind of motor, it's what are you trying to lift or move with it. All wiper motors will have that kind of current draw if stalled. If you are lifting heavy prop arms with it, you will require a lot of current. I can run mine on a 5A power supply as well. It just will severely limit the amount of torque that the wiper motor has. It won't be able to life as much weight. If you are using a 5A power supply, you might as well use a much smaller motor because the lifting power of the wiper is very low at that power rating. You can run it on .5 amps or less if there's no load. I specifically used a wiper motor because of it's ability to provide crazy amounts of torque, but the only way to get that kind of load capacity out of it, is to feed it LOTS OF POWER. I'm talking current here, not so much voltage. You can run it on 5 Volts, but that is less than half of what it was designed for, so it will move more slowly, and will again have less torque. It all depends on the application and what you are trying to move or lift.
