Please post the motor's datasheet as well, if available. I doubt it has a series resistance of 1k, as you previously posted.

I don't have any specs of the motor, I just place a resistor, not really meaning the true load

Ok ... what are the motor's physical dimensions? can you post a pic?

The how can you know that the 2N2222 transistor can drive it?

its a normal DC 12v motor, black and white wires are 12v, the other four are an encoder

I measure the current and is less than 200mA, I guess the 2N2222 can handle up to 800mA according to the spec

That is choose as 2SC1384(1A) is better, for the power dissipation, you should choose a rating Ic is three times or more of calculation (or measuring) values.

Yes, that should be okay.
I thought you didn't know how much current the motor took since you had no specs on the motor and didn't use that load for your simulated motor.

 

Too many wires in that motor... if I didn't know better, I'd say it's a brushless.

 

Any idea why the diode is letting the voltage pass to the regulator side?

I know that is a normal dc motor because I add the encoder to it, it's a magnetic quadrature encoder 40ppr

That is using as 2SC1384(1A) is better, choosing a rating Ic values for three times or more of calculation or measuring values is good for power dissipation.

I have two 2.7v 10F supercaps in series

When you in series with two supercapacitors then you should in parallel with a balancing resistor (Please see the section -- Why do ultracapacitors require balancing? What are the balancing methods?) for each supercapacitor, the R values is :
R = (Vcc/2)/I
= 2.5V/114 μA
= 21.923K
You can choose two 20K.

It's not, unless the circuit is wired differently than the schematic.

I think the capacitor discharge is through the transistor resistors and the lack of a resistor on the MAX809 output as I previously stated.

I didn't know that, thanks for the tip

I will re-wire again the circuit, maybe I did something wrong, thanks for all your help guys, I learned a lot
