Acurite Atlas - Aspirating fan motor replacement
« on: November 20, 2020, 09:45:27 PM »
Hi, new member.
I think the bearing(s) are bad on my aspirating fan motor. I have a known hearing problem and I can hear the thing grinding away 40 feet in the air. I brought the unit to ground level and tried a drop of machine oil, but you can feel the shaft vibrate in the housing when powered by the solar panels.
Pic below are the numbers on the back of the fan motor. Can it be replaced?
Funny thing..I just got this unit back from Acurite in Sept for wind calibration adjustments and they did not mention any issues with the fan motor.
Any suggestions are welcome.
Thanks,
Shawn

I don't know about the replacement but I do know if the motor isn't set perfect in the housing it will make some noise plus can lock up . I had that problem last year and removed the fan housing and lubed it up and was very careful about putting everything back together . But after a week it was sounding like dry bearings mainly when it was cold outside for some reason . I took it down and found one of the tabs wasn't pressed all the way in and that was my problem . Like I said maybe someone else here will know where you can find a replacement motor but I don't . Here's a old breakdown of the atlas with some good pictures also . https://www.wxforum.net/index.php?topic=35220.0

Thanks for the info...this thing was vibrating even after I had it removed from the housing and was just holding the motor in my hand with the solar panels in the sun.

Well hopefully someone on here can find a place that sells a new motor for you . Maybe use chat on Monday with Acurite and they can give you a hand on where a replacement motor can be found .

I have no idea what fan motor your PWS takes, but this is a place to at least start. This link shows the aftermarket VP2 replacement.

Thanks.. i appreciate the help. While I was fooling around with oiling the motor shaft, I broke the wires, so I put the unit back up with no fan. It is almost winter here, so I have some time to work on it. The temp reading is actually not my largest concern anyway...I pay more attention to wind, rain, humidity, dew point, etc.

Common misconception is that a fan is to combat heat. It does to an extent, but the main purpose is to combat lack of wind, regardless of "how hot it is". Also realize that just because you're unconcerned with the temp, that's exactly how your humidity and dew point are extrapolated.

I am kinda new to weather monitoring.
I did not say unconcerned, but temp was not high on the list..but I do appreciate the education understanding how things are calculated!  [tup]
