I have a number of fans, my favorite is the Emerson Jr.  I have one now that I have a question about.  It runs fine.  It has a great lengthy spin down.  But when starting it seems to barely have enough "Umph" to get going.  First 2-4 seconds are painful as you never know if your going to have to give a finger boast or not.  But all else is fine.  Any thought why the starting torque seems to not be there but it runs a speed just fine?

Hi Joe!

We need additional info on your fan... We need the wattage and amp draw after running an hour would be helpful... Picture of the jr. so we know what fan we are working with... Have you removed the stator? what kind of maintenance have you performed on your fan... Starting torque is not real exciting on these fans and they are a little touchy after working on them...

Joe ,
Have you changed the oscillator grease ? That too
Can add a slow start due the dry grease. Just a thought

Yes the whole unit was cleaned down to metal.  New grease for sure.

You might try taking the oscillator off the back and see if it starts faster.
The rod that goes to the blade might be binding somewhere along the line...
Happy Fanning!

I am curious what you find out. John has the best approach. When you disconect the linkage to remove gear box test it then too before removing the gear box.

If it’s haviing a slow start a load of something cause it to have a slow start up would. It will have a higher amps as a reading. Then drop as the fan gains speed ?

Joe is your motor getting hot at some point or is it just a start-up issue? I've seen a couple of those jr's that started up ok , but ran too hot. Wondering .

No it never gets hot.  I've run this one a lot and never gets above warm or about 112 degrees.  I use an infrared thermometer to check.

I've had interest in this fan but not selling as most think it should just fire up without 1-2 seconds to do so.  Has anyone else seen this in a fan they have?  Done or checked all the things above in this thread.  I've used it myself all last summer without any problems.  Would like to sell and move on to next purchase.

Joe,  I've got a red badge jr that is one of the best running jr's I've restored. It's .57 amps or thereabouts and runs cooler than any I've restored. It has the same problem. It's a flip of a coil wether or not it will start on its own, and starts slow. I bring it with me on trips and meets wherever I go. It's quiet and cool and pushes good air. Unfortunately it is unusable around the house, i.e. The wife will never reach her hand inside a cage and for good reason. So potiental buyers have a point. But I can't help you. I've taken mine apart many many times and everything is good with the fan. Just sometimes it won't start. Like it wasn't wound "hot" enough. I love it though. Got it with a broken neck stem and missing lots of paint. Made a new neck stem and it is one of my favs, unpainted and unloved looking but so much character and runs flawless, once it starts...  lol

Thanks for this bit of news Lucas.  I am actually glad to hear that you too have a fan that does such.  Whatever the reason I think it is normal on the more rare occasion that it happens.  I have a red badge waiting to be worked on once my "thumb" heals from surgery.  I'll probably keep the fan as I have four Jr.'s that span the range of production, except for the "B" version which is way different than the tapered bearing models.  Again thanks for sharing.
