I want to run a electric motor at 6v from a wall outlet. I need to know what wall plug transformer rating I should use to run it. Here is what I have.
Better stay away from your USB with motors of any sort. The on/off spike could take something out in the computer. If you care about the Router, try not to go much higher than 20 % above rated voltage. The current draw from a motor increases drastically as you double the voltage applied. Simple adapters have only a transformer, some diodes and maybe a capacitor. When trying a higher voltage, try to get a meter in the line to measure the current. If you exceed to rating for the adapter, expect smoke. Try adding a capacitor (say 1000 microfarad rated for 20 volts) [watch the polarity] to the leads coming out of your adaptor. Better quality direct current will make your motor run better. Simple adapters can be voltage controlled by the variable speed controls available for ceiling fans. Some can be controlled by regular light dimmers. Cheap adapters may be available from Radio Shack as returns where someone mashed the jack.
You need a device called AC to DC adaptor,output choose 6 volts DC with a current rate at least 1 ampere. Suggest you go to the Dollar shop in your area to search one if your are lucky. Or search more Dollar Shops, it costs $1 or $2. It comes with different output connector. Just cut it off,connect two wires to the DC motor that you have. Some printer or scanner might use the same adaptor,read its output information. If you can find a scrapped old computer,take out the power supply . If it still good (fan running),you can get a very high current output 25 amperes or more at 5 volts (usually is between the wires red and black). This power supply is perfect for your DC motor to run.
