I am looking for Info on little motor.Somebody got to know something on this.It is 23/4 inches high,2 inches wide, and 21/2 inches from end to end on the shaft.And yes it works.The wire insulation looks like almost a wax type covering.I am guessing around 1885.Perhaps this is a salesman sample.I've never seen a bi polar this small. Who is Ajax?

This is a toy motor I believe, not sure if it is a Bi-Polar motor though.

The 2nd motor from the right-front is a tiny real bipoloar motor, about the same size as yours, but the armature is multi-pole.

Your Ajax motor is sweet. I see these on feeBay often. Good catch!

I call your kind a "uni-pole" motor, as it only has a single coil to excite both the metal "poles". The motor in the rear-left of the photo, just in front of the largest motor is a uni-pole Erector set motor, similar to yours.
I collect mini-motors, some of these here are non-functional salesman sample paperweights, others are real, functional motors. The green one on the far right is an AC alternator, complete with slip-rings and brushes. Post your motor photos! I LOVE little electric motors!

More views...yes, the tiny GE loop handle fan works and oscillates, powered by two AA batteries.

I started collecting those in the 90's and have a lot. They're boxed up, in the attic. Your motor is a bipolar. We refer to those as 'toy electric motors'. They were made from about 1890 to the 30's. You could buy them assembled or as a kit.

The little motor is a bipolar. Later we got quadripole motors. The coil produces a N and S pole. But at the same time these came out we had Pacionotti (man I hope I spelled that right) motors (many poles). By 1900 we had AC ceiling fans with lots more poles.

Man that's nothing...we have lots of poles around here. Why...if memory serves me right there is a Pacionottiski living at the end of the block. :tumbs
