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?

Author Topic: How do I drive these Delta fans with varying speed? Read times. Hello everyone, I have recently obtained a box of like 30 or so delta fans from a source that shall remain unnamed for now. I thought they might be the standard yellow tach and blue PWM wires of a standard PC fan, but they aren't, I terminated them in a 4 pin fan header and the fan ran at full speed. So I thought maybe my dell test motherboard was being

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.

No, Leave Fan Cable Stock. 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" :. Im using Uno. It only says that "Blue wire frequency -F00 " but i dont know what that means. So I thought maybe my dell test motherboard was being In addition, according to the specification, computer fans are controlled by PWM with a frequency of about 25kHz. Cryptocurrency has taught me to love math and at the same time be baffled by it. I don't think the fan is damaged as well so i really need help. Add Sleeving to the Fan Cable None. I tried switching the position of the blue and yellow wire respectively. Sleeving Service. 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. The document also mentions that the PWM input voltage ranges are 0.
