Mart,
I think that those motors are not suitable to convert them in attraction motors, because you do not have a stator. It will be SO hard to make a good stator from scratch. Maybe you could get a grinder motor? Today I disassembled one of my old and broken grinders. I am talking about such one:
And here is what it has inside:
You see, there is a perfect stator inside made of high quality silicon steel. There already are two coils wound on the poles and you have an easy access to the coil wire ends. All you have to do is remove the coil wires form the rotor and cut out some of the rotor poles as Elias did some posts earlier. And you can use the original housing and bearings. This way you can easily modify such motor to run in attraction mod. All that is left, is the circuit and a commutator.
The only disadvantage is the airgap. This one has a total airgap of 1.5mm, that means 0.75mm on each side. This is not very good.
Hope this helps
