So i have a water pump driven by a brushless motor I am trying to drive. im trying to control with a transistor and PWM. Works FINE when I give it the full 12 V. Moment I change it to an analogwrite, doesn't work. I'm still measuring the exact voltage drop across the motor. But I've verified this fucker works with less voltage.

I don't know much about pwm, so what could the problem be?
