Delta pwm fan

I'm currently working on a source code to control the speed of a fan through a potentiometer in arduino. However, the code does not work and the arduino only runs the fan to full speed. Would really appreciate some or a lot of help as this is for my thesis and the deadline is nearing like only a few days left, still have to do the "paper" :. I even used put search it with quotations marks and still can't find its specs for the wiring. Is the blue wire really for the PWM, then yellow for tacho output? I don't think the fan is damaged as well so i really need help. If you search for Arduino PC fan controller, you will get many, many hits. These are all 4 wire fans. An oscilloscope will tell you which wire is your tach. Unfortunately, i dont have an oscilloscope. Hi there. I already read this datasheet as well but it does not specify what is the yellow and blue wire for as it is a 3-wire fan model, i guess. It only says that "Blue wire frequency -F00 " but i dont know what that means. One thing that I have read is that there is no need to add a mosfet to control the speed of the fan as there is already the PWM wire, wherein control speed of the fan can be controlled through it. You do not set the control PWM pin as an output and it is a bit strange to determine the duty factor.

Unfortunately, i dont have an oscilloscope.

A medium-high speed case fan at x x 25mm. It operates at RPM and delivers air flow of With PWM feature, this fan has the ability to adjust spinning speed to achieve a balance of cooling and acoustics. It's also built to be tough to withstand long-hour operation in demanding environments, thanks to industrial-grade materials and top-notch, high-quality dual-ball bearing. Add to cart. Ships from China. Price Alert.

It utilizes the traditional AFC 7-blade design, features a tach output and like every Delta we stock, uses ball bearings for long life. In addition, it is available with your choice of optional cable sleeving. Skip to the end of the images gallery.

9v battery snap function

There was an error while thanking. Did you miss your activation email? Skip to the end of the images gallery. Then I tried voltage controlling it, it was still pretty fast at 7v and wouldn't even move at 5v, so voltage control seems unlikely. JavaScript seems to be disabled in your browser. Now I'm really confused. RoHS Compliant. An oscilloscope will tell you which wire is your tach. Sleeving Service. This fan is a standard PWM pinout. It could be that the fan has a custom firmware that accepts something other than the standard 25kHz PWM.

No, because the 'FG' pin is apparently an open collector output tied directly to the motor driver, and consequently it will exceed the maximum voltage rating of your Arduino pins. RoHS Compliant. You might have to sacrifice one and perform an autopsy. Controlled by a PWM 4-Pin fan connector ensures this fan will only run at the speed needed for your needs. New replies are no longer allowed. Answer this Question. You have already demonstrated that by grounding the yellow wire PWM input the fan will stop spinning. This topic This board Entire forum Google Bing.

After some time the fan goes on fullspeed. Quote from: mariush on February 11, , am. Be the first to review this product. No, Leave Fan Cable Stock.
