A question about servo motors

Here is one of those brushless servo motors. 

Interesting the speed difference between the two machines using the same motor and same size handwheel.

I'm pretty sure both were run at minimum speed for that motor.  Both are slow enough for me I think.  I have to get some leather to try.

Are they really different?  I don't see it.

I thought the video with the Singer was slower then the other one. Maybe just me. Either will give you the control for those places where you need really slow precise thread placement control. Nice simple speed reducer setup.

I've used the same method, bj139, and it's a very effective way of getting slow speeds on a machine. I also added a speed reducer to one and it made yours look like an express train!

$18 for the pulley is a cost effective way of getting slower speeds.  My reaction time is quick enough for this lightning speed setup.
