Thanks for your reply Peter. There are so many ways to deal with this I'm having a hard time sorting it out. If I where to stick with an outrunner solution, one thing comes to mind, I could get a kit and wind the motor for 220 and use a VFD. Also, I suppose there is plenty of fluid available for cooling already on my mill. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
