You need a 12 volt AC to DC converter which are very, very common. The 12VCD 5amp power bricks that you use with laptops and game systems work perfectly and are readily available almost everywhere cheap.A wiper motor is normally powered by a car battery, right? If you want to use it with a prop, does that mean you have to connect it to a battery? Can it run on household current? Thanks.
Easy, a power inverter. Just make sure you get one that has more than the required wattage your device needs. Here's one.Here is a question for you.....OK so its possible to go from a car battery to House current.
But is it possible to go from a House current prop ( 120 Volt ) and convert it to using a car battery ( 12 Volt ).
I am going to have our Hearse parked in front of our home, and I am wanting to run a Fog Machine inside the Hearse, but would like to run it on 12Volt, as opposed to using its required 120 Volt supply.
How can I do this???
Ahhh, but that's the big advantage with PWM, you don't lose any torque from the motor. Simply reducing the voltage to slow the motor does result in loss of torque but PWM does not.PWM (pulse width modulation) controllers are available and allow you to adjust the speed of the motor, but they also reduce the power and, therefore, it depends on the application and how much resistance your prop provides how well they will work for you.
