Okay, now that we've settled that,
there remain two drawbacks of direct buffering in analog operation:


1. Such a huge capacity in parallel to the motor,
will make it virtually uncontrollable with a standard controller,
because of the stored charge.

Your controller has to be of the four-quadrant-type,
i.e. actively discharging the capacitor to the set voltage.


2. Supercaps AFAIK do not respond well to the simple circuit Si. featured.
You have to use diodes, too.
The simple circuit needs double the number of capacitors.
