Floor Fan Speeds Up And Slows Down

Had it for about 6 months.

Ceiling fan up or down. When the truck sits and idles the blower works fine but when your driving and start to pull a hill the blower slows down when the truck is at about 3000 rpms nothing really is coming out of the vents as soon as you let off the accelerator it picks back up to normal. Is it the motor or the motor 3 speed switch. In your breaker box flip the breaker that powers your fan to the off position.

I hope this information helps. The machine runs fine until it does something heavy on cpu like for example video processing or bulk compiling and then the cpu fan powers up. Were going to set certain fans to speed up or slow down based on the temperatures of certain sensors.

This in on an old window fan. I have put oil on the bearing ends on both sides of the motor. My car has 161000 miles.

The next best thing is a fan dimmer or speed control meant for use with fans and has a minimum speed adjustment. Here the dealer will help you to send your fan to the manufacturer and yes it will take near about 10 days to get a replacement from the company. Ive got a basic 12 oscillating fan.

It runs at full speed for a little then slows way down then speeds up again this repeat constantly without a pattern. It fit perfectly in my window so i dont want to get rid of it. My car has an automatic transmission.

However it seems to have screwed up the cpu fan device driver somehow. What is causing the motor on an electric fan to slow down and stop. Some fans have a combination start stop capacitor and some have a capacitor for each.

Other fans use multiple capacitors for speed changes. I can hear a slight hum and i can see the blades turning veeeery slowly. If i leave it on and wait 2 5 minutes the fan will just suddenly start working properly.

So far so good. So for example we can set our cpu fan to speed up when our cpu gets hot thus helping it cool down. They cost about 10 next would be a capacitor type de hummer control and it gives you about 3 usable speeds if the control fan are matched.

You could also for example set your front chassis fans which are next to the hard drive to speed up when the hard drives get hot. This only seems to happen when the fan has been off for awhile. The torque to drive the motor of your electric fan comes from the magnetic field induced in the motor coils when electricity.

Now if your fan winding is faulty then it is better to purchase a brand new fan since repairing the winding section does not increase the fan speed.
