I have a fairly cheap breadboard power supply and a motor.
Now if I touch the wires from the adaptor (the thing that plugs into the power supply to provide it with electricity) the motor works fine and spins happily. I can adjust the voltage of this adapter to 3 volts - 12 volts, and the motor spins fine at all voltages. So I know the motor is working fine.
However if I plug the adaptor into the power supply and then try and power the motor from the power supply, it doesn't work. I try with both the 5 volt and 3 volt output of the supply. In fact the power supply appears to shut down - the led on it turns off.
What gives, why can this power supply not drive the motor? Is it just broken or is there some law of electricity I am not yet aware of (likely)?
Ok, so this is the motor I have : motor
And the power supply I have is something similar this : power
I can't find many details about the motor. But I have noticed for the power supply it says :
Maximum output current: <700 mA;
So I am guessing this is the problem? The motor likely needs more than that, especially if it needs 10x its requirement to get going.
