Some of the stepper motors available from SteppersOnline show two pairs of screw holes near the edges. And you are correct. Youtube videos of stepper dismantling show that it's pretty thin near the edges and the windings are really close. However, I've read that once you dismantle a stepper motor it loses some of the magnetism. That they are magnetised with much higher pulses of current when the motor is assembled. But that might also be an urban legend. Anyway, the back end also has the motor leads coming out so pulling it apart may also damage it. Or not. Easier to just order a new motor perhaps. John

The metal end plate might be a lot thinner than it appears from the outside. Is it thick enough to support threading? It might be a thin diarist part. Maybe look inside first? But on the other hand, the load on the mounting screws would be nearly nothing. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
