42" drum fan motor


Hello All
I have a 42" drum fan i bought from Lowes for 300.00 4 moths after I bought it it started making a whining noise and the blades were slow to start
then one day they wouldn't start at all. i tried calling the company that makes it but the 800 number is a help line not the company and they have no way to get ahold of them as they are in shanghai

I need help figuring out what i can do to get this fan working again it doesn't even list the Hp of the motor or the RPM
I can tell you it bolts on the back to the frame with 4 screws its about 5 1/2 " across and 5 1/2 " tall with a 2" shaft that uses a single pulley for the belt to move the fan blades..
can anyone help me find out what type this is and where I can find another?
The only thing on the plate was this..
Thermally protected capacitor 10mfd
Com -white High - Black Blue- Med low- Red
120vac 60hz 450w INS CL A

42" drum fan motor


A 450W motor is about 1/4HP. It's a 2-speed motor, which you may or may not care about when replacing it. I'd say you should take the motor out and take it to Grainger or another industrial supply house, and see if they can get you a replacement. Alternatively, measure all the important dimensions and look for one online. Burden Sales (www.surpluscenter.com) usually has a suitable cheap replacement for most small motors. The replacement doesn't have to be exact, or even really close. They key things to look for in a replacement are: Enough power (at least 1/4HP, more is fine), correct direction of rotation, mountable (even if you have to drill new holes), and the ability to line up the motor pulley with the fan's pulley. You may need a new pulley if the motor has a different shaft or a different speed.

42" drum fan motor


So the question is how do i find the right motor or rather what would it be called, every time i look I find attic or evap motors.
And I would prefer to find one that will work with the hi/med/low switch if possible or at least have a high and low.
and will my pully work with any motor? or will i need to get a new one too?

Would a 1/4 hp motor be strong enough for a 42" fan here is a picture of it btw

Did you look at the old motor and measure the important dimensions? did you look on the website I linked to to find one that might work? I answered some of these very questions in my previous post. To reiterate, you need a motor that physically fits and is at least 1/4HP. It should run at the same speed as the old one, or you'll need a different size pulley so the fan will turn at the same speed it used to.

I can't tell from the Lowe's picture how the motor mounts. Can you post some pictures of the motor, showing the mounting method and the pulley, preferably annotated with dimensions?

Have you tried to repair it ?
A lot of times it is just dry/dirty bearings,
Clean the bearings/sleeves and apply some thin machine oil,
Usually this fixes most motor problems,
Worth a try !
Other wise check the junk shops,
for another motor.
Finding motors is not hard,
But finding one with the same mounts,
Might be a little harder.

Sorry, but they will take it back. Bring it to the store with your receipt. Insist if you must. I would.
