Hi,
I need to start a DC motor from 9V battery (PIC MCU controled, using 5V relay and BJT).
It has to start as fast as possible and if possible revolve only one time or in the worst case, spin very shortly (<100ms). There is a little weight attached to the axis so it behaves as a rumble motor which adds some extra inertia.
From what I know, a DC motor that starts requires a lot of current in the first moment so I was wondering if using a large capacitor (25V 100UF?) near the motor could help to supply current for the short period of time when motor is starting.
Would you have same suggestions?
Thanks
