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.

No, delta pwm fan, 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. I tried switching their places as the speed does not adjust according to the potentiometer.

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.

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. Skip to the beginning of the images gallery. Found a better price?

In addition, according to the specification, computer fans are controlled by PWM with a frequency of about 25kHz. I suggest connecting a function generator or even a and play around until you find something that controls the fan properly. Usually it doesn't work well, with the fan basically making nasty whining noises and not spinning up unless you go to pretty high duty cycles. 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. Did you miss your activation email? Length: 0 of Add to Wish List Add to Compare. Your motherboard probably cannot source enough current on its PWM control output pin for this fan. Just fill out this simple form and we'll see what we can do for you. You have already demonstrated that by grounding the yellow wire PWM input the fan will stop spinning. 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. Im using Uno. Skip to the beginning of the images gallery.

Read times. This topic This board Entire forum Google Bing. I can't seem to find any datasheets for the 4 pin flavor of this fan, only 2 and 3 pin versions. Usually it doesn't work well, with the fan basically making nasty whining noises and not spinning up unless you go to pretty high duty cycles. Add Sleeving to the Fan Cable. In addition, according to the specification, computer fans are controlled by PWM with a frequency of about 25kHz. If you search for Arduino PC fan controller, you will get many, many hits. This fan is rated at 4. You might have to sacrifice one and perform an autopsy. Add Sleeving to the Fan Cable None. For the best experience on our site, be sure to turn on Javascript in your browser.
