Part of the solution might be to hold the high-speed spindle in place with the 4 tapped holes in the face rather than with the drawbar. There are laminations available with a decent-sized central hole that would allow a through-bore motor to be made. http://www.gobrushless.com/shop/index.php?app=ccp0&ns=prodshow&ref=SC+65mmstator I think an ISO10 holder could be made to fit at least partly up inside that, and you could probably still get at the face mounting bolts. However I have not found a drawing which shows them. An Inrunner might package more easily. Rather than a brushless motor, I wonder if gearing up the existing spindle is an option. I have seen a centrifugal supercharger drive which used friction drive to achieve a large speed increase using only a slightly resilient outer drive ring, and slightly-floating-mounted planets. These are almost ready-made for the planet job: http://simplybearings.co.uk/shop/advanced_search_result.php?categories_id=4461&1_10=9205_1&21_210=-1&22_220=9205_22&23_230=9205_23&x=22&y=9&extra_field_filter=1 -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
