Did you really mean you gave it 20% power?

At 12 volts at stall, you are giving it 1020 watts of power. 20% of that is 204 watts power. I doubt the 550 could dissipate 204 watts for 15 minutes with only mild heating.


Maybe you meant you gave it 20% voltage?

20% of 12 volts is 2.4 volts. At 2.4 volts at stall, you are giving it 41 watts of power. Even at that lower number, the 550 would get pretty warm after 15 minutes.
