This circuit does not appear to be doing much of anything. Please provide a functional description so we know what it is supposed to be doing.

The circuit was copied from this site below, for a better understanding please read. I have not built this circuit yet, but i think I will later. http://electronics.stackexchange.com/questions/152432/555-timer-boost-converter-doesnt-meet-spec

It didn't make a lot of sense to me that little change happened.

The motor is a dc device, has a 2 amp start current requirement, and only shows rotation @ a 1 second time base, unfortunately the circuits out put is AC, less than 2 amps, and drops off at a 1 second base rate.

Where is this a.c. billy?

rich AC is when it's not DC. If the output capacitor is increased to about 4.7mf, then it is closer to DC, still needs a bit more filtering but DC. Got rid of the feedback circuit, it needed a bit more work and was only confusing the circuit. http://everycircuit.com/circuit/5476381117120512

Its not a.c. The term is more than its self describing name of alternating current, polarity reversal is also required. The polarity is never reversed for Yra, and the current in your cap alternates as much as Yra's. All dc caps have this positive negative cycle the same as a battery.

The voltage of concern is the voltage applied across the motor, the capacitor is and there to help reduce AC component of this voltage.
