Yes, in fact this is how my coolant pump is wired. You don't get the same power output, and the motor needs to have an external star point so that it can be wired for the lower voltage, but it works fine. In fact, many of the cheaper single phase motors are exactly that, a three-phase motor and permanently connected capacitor, with no centrifugal switch. I don't know if it is still the case, but the single-phase motor we bought from Machine Mart was exactly this, and had far too little starting torque for the vehicle lift we wanted to run. http://www.machinemart.co.uk/shop/range/details/230v-110v-single-phase-motors/path/single-phase-electric-motors -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
