TENV Motor Internal Fan: Required?
« on: March 27, 2017, 05:07:18 pm »
I have a TENV fractional HP (1/6 HP) Leeson motor on a septic aerator.  The bearings froze and are shot after just 2 years.   The armature has a plastic internal fan that makes removal of the armature and replacement of the end bearing difficult.  There is no external capacitor.  The fan can probably be removed with a little heat, but I am worried about getting it reattached well.  Of course, I would use Loctite if I get to that point.

Question:  Is the fan really necessary?

TENV - Totally Enclosed Non-Ventilated (for the young players out there)

IMHO, no, you could leave it off for all pracitcal purposes.

I disagree. Noone puts a fan there without a reason.
Note that the fan is internal, and probably serves to eliminate local hot areas by circulating air within the motor.
Externally, the motor is TENV, but that's another issue.

SOLVED

I as able to get the fan off without heat or damage.   Will re-install with a little Loctite.  I would rather re-assemble as built.  My fear was that if the fan got damaged in the process, it is not a part I can buy retail.

Thanks all for the advice.
