Yes, the mechanical parts of a 1750 motor are identical to those of a 3000 rpm motor (or whatever your 60Hz ones do) so they are generally fine at double frequency. One advantage of doing it this way rather than gearing up is that you have more torque at the lower speeds. I would expect the DC motor to perform better at low speeds than the induction motor, though. If you can drive it. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
