I found out positive and negative powerlines by using my multimeter to check which pin of the Panasonic AN8244SB is connected to the pins on the big capacitor.
Then I connected a 2,2k resistor to ground, turned on my powersupply at 12V (beware: voltage must be within the voltagerange of the capacitor!) and touched the other wires of ma 6pole connector wire with the resistor (note: 12V / 2200Ohm = 0,0054A = 5,4mA - just to avoid burning the chip).
Hitting the right pin the motor started to rotate. Tipping it multiple times it became faster and faster.
At this point I couldn't sense any optical or acoustic difference between 12V and 24V.
To ensure the resistor isn't limitating the speed I switcht to an 1K resistor, but again: no difference.
