I have acquired a second hand AM03 Pedestal fan, with the intent of using it on low speed so that documents are not blown all around the room and magazine pages blown closed, etc.
When I saw it demonstrated at the seller's house it worked fine. When I got it home and powered it up I was annoyed to hear a whining sound from the motor that approximates worn bearings. Worse at low speed than high, it's especially bad when the fan is powered off -- the motor then grinds down noisily to a halt.
So, I pulled the fan apart to be greeted by a Johnson E9IHM-240 stepper motor. Although it feels OK when rotated by hand, I suspect the bearing at one end is shot.
Now, my problem is to find a replacement motor. Given that it's a Johnson -- a long-established Hong Kong based company that makes hundreds of such motors for thousands of OEMs --I thought I'd be able to buy one easily.
However, Googling around I have been unable to source it, including Johnson Electric's own site which mentions it, but that's all.
So, given the wide knowledge base on this forum, I'm hoping someone might be able to assist me in that endeavour.
