Re: [CAD_CAM_EDM_DRO] Re: Slo-syn Steppers

Brian:

On the other hand, I've had my stepper motors totally disassembled several
times, they are still powerfull and robust and work very well. While its
true some steppers don't like being taken apart, some don't care. Generally,
the larger the stepper, the more it doesn't care. (at least in my
experience)
