Simple project, I am trying to control the speed of the fan using PWM. The fan is 12V, 1.5A at max speed. I am using IRF830 to control it as per project from:
https://www.digikey.com/en/maker/pr...raspberry-pi/c5061a5c6cf646b69a2ff6d698298422
The problem: I am not able to achieve full fan speed, the max voltage that I measure with the fan connected is about 6V not 12V as expected, without the load fan) it is 12V. Also, without IRF830 controlling unit current, is 1.5A, with the unit drops to 0.8A and again, speed is only half what should be.
What should be a solution?
Thanks in advance
Robert
