    DC motor brush failure

    Hey Clyde38, Thanks for this paper. I believe it a brush type problem, where the film is too thin. This paper explains the phenomena very well, and gives me some things to try. Thanks again!

    DC motor brush failure

    They are PWM driven. Yes, in this case the lead screw is lifting a mass.

    DC motor brush failure

    Hello, I have a small DC motor that is burning up the Negative brush. See photo. Anyone seen this before? Any ideas what could cause this? The motor is used by me in many linear stages, but only fails in one. The one that fails is unique only in that is has a faster lead screw. It operates at...

    CAD/CAM paperless

    Hello, We manufacture most or our parts in house and are looking to get CAD and CAM to work together seamlessly; even at the possibility of eliminating 2d drawings. Are many using the Y14.41 3D dimensioning specs? Have you gone away with 2D drawings completly? Thanks, Terry

    CAD/CAM and 3d dimensioning

    Ewh, Are you the mancufacturer of these parts? Is there any more details you can provide? We manufacture all parts in house and are looking at the possibility of eliminating 2d draft. Thanks for the info, Terry

    CAD/CAM and 3d dimensioning

    Hello, I'm interested in the CAD/CAM ability of UG, and have a few questions: Can you tolerance the 3D models? Can you apply a finish coating to models, that will account for plating, anodizing, painting, etc? Does it do tolerance analysis? Does the CAM read tolerances form the CAD models...

    CAD/CAM and 3d dimensioning

    I'm looking to get the CAD and CAM to work together completly; correct nominals and tolerances. A type II anodize can add .002". Are many using the Y14.41 3D dimensioning specs? Have you gone away with 2D drawings completly? Thanks, Tery

    Linear Rails: THK Vs NSK

    Barry, What is your experience with Hiwin. I have started evaluating them, but the rails are critical to our design and am afraid that in production the quality may not be as good as the few prototype rails they provide. Thanks, Terry
