MOSFET controlled DC motor too slow
I want to control a DC motor using a P-channel MOSFET.
I tried the motor with a 5VDC power supply. It works perfectly and speeds up in no time. … Now, I wanted to include a MOSFET. I used FQP12P20. I connected the source to +5V, the gate to GND, and the drain to the same motor. The motor still works, but it takes seconds to speed up. …
