12 pole
Hi all,
Here is my first 3 pole modified motor(smaller one). I used two different motors. One had external brushes and one had internal brushes. So i only had to add a small section of housing to make it work. I just used JB weld to attatch the extension. Only bad thing is i have zero shaft left. But its pretty torquey!
The other parts you see are a 12 pole armature and brush setup i'm gonna play with next. The motor is from a blower motor for an automobile. It has about a 7" shaft on it! Considering a metal-less housing, not sure though...
Instead of adding a commutator, because i don't have another identical motor, i'm considering splitting the commutator and having a dual commutator on one side of the motor like UFO posted earlier. It will deffinently be a little harder to accomplish, but i think its doable. I could chuck the shaft and just groove the comm. to split it(in the lathe of course) but then i would have to drill vertical holes through the base material of the comm. to allow the wires to pass to the upper comm. Does anyone know exactly what material that is that they bond the copper too for the comm? I think you should be able to drill through it. My other issue is i will need the second set of brushes. Does anyone know if a carbon brush can be cut? Or would it just crumble? L ots of question?
But its alot of fun tearing stuff apart and makin something else out of it!
