Room Blower fan motor upgrade

funflyer · Nov 30, 2014

Looking to start my spare parts collection, I searched the net for days looking for a good ball bearing motor for the room blower fan. Seems that almost all the good BB motors are 230 volt but I managed to find one 115 volt BB motor with the same dimensions and close to the same rating as a D132. It's a shaded pole 3 speed that runs 1550 RPM on high. The shaft is 2.5 inches long but should'nt be a problem. Made by Universal Electric in Michigan. Any electricans out there see any reason this motor won't work?

Nice motor, however, no way to lubricate the bearings. You see, it's the dust of operation that eventually eats up the bearings. What I do is replace the sleeve bearings with ball bearings from a jobber like Applied Technologies (Detroit Ball) but I make an oilway so I can lubricate them and then I lube my motors every spring when I shut the unit down I go by the old farmers saying..... It never breaks in the barn.

The stock motor is really as good. Will be a Fasco I believe.

Yep, the stock motor is a Fasco but there are no oil holes and man does it run hot. This BB motor has covers riveted on so there is no problem reengineering them for access to the bearings for the occasional lube or replacement.

Get yourself a needle oiler (available at a hobby shop or Hobby Lobby or a box store) and some lightweight synthetic oil and lube them with that....yearly. Do the same with the Fasco. All shaded pole motors run high ambient temperature, it's inherent in the design. Nothing to get concerned about. A shaded pole motor is very inefficient because it phases and that creates heat.

If cost was no object and we were all millionares, every motor would be a vector wound with frequency drive, but thats a fantasy.

Is that with or with-out dilithuim crystals?

..........poof, it's summertime and ac time Bart......

Get those phasers on stun......

I actually run a frequency inverter drive on the welding hood blower in the shop to vary the CFM intake while not loosing motor efficiency (horsepower) but it's not a cheap date.....

Why use a ball bearing that needs to be oiled? I would use a double sealed (viton) quality bearing and be done with it. I'm guessing that this new motor uses single shielded bearings which would need periodic lubing so they're already on my list of things to change.

Not sure they would last because they aren't hermetically sealed. might last longer but it's the minute dust particles that eat them. A consideration for sure. Myself, I just oil them.
