    Question Bridgeport - Superior Stepper Motor

    Does anyone have a Superior Stepper Motor, for '80's vintage Bridgeport CNC (knee mill), with Boss 3 to Boss 6 control vintage?
    Bridgepoert #025805 (alternate for #026744).

    Thanks, Dan Becker / 920-217-1534

    I've got two very large old Bridgeport steppers that were taken off an old CNC Bridgeport but there are no tags on them. The only ID I can find is on the face, "1926749". I bought them in this forum <20 years ago for a project that didn't happen. These are very large, black , heavily finned motors. Shank is 5/8"OD x 2 1/8".

    I hav eno idea if they are what you're looking for but thought I'd let you know.

    Hi, The stepper motor that failed (open winding) is a large black finned motor, with the same shaft specs. Could you send a pic (PM) of the back end of motor with circular cover removed? We would be interested in both motors. If I send you the terminal list, could you measure resistance on the terminals after the cover is off? Thanks, Dan Becker
