Hello,
I salvaged a small DC motor from a old camera, it has not details of voltage, amps, model number, nothing.
I tried to run with 2 x 1,5 AA battery, and it works pretty good. It will draw around 70mA. It will work fine also with one battery.
Used it to play with arduino (PWM) using a transistor as driver. Everything works fine, then I decided to use a small breadboard power supply module 3.3v/5v instead of the batteries, and the problem is that from what I can see it is not able to supply the starting current needed to make the motor spin.
It will draw around 170mA and the power supply led will even fade. If I give "help" to the motor with a finger it will start to spin.
I guess the problem is that the power supply is not able to handle the starting spike of current needed, so I was thinking of using somehow a capacitor in parallel with the motor to give that starting help, am I wrong with it?
If so, can you guys give me some help with it?
Thanks in advance
