Re: [CAD_CAM_EDM_DRO] 1KW, 30KRPM Router as a Spindle/Motor?

Hi;

The items you left out in your equation below make all the
difference. For example what is the intended usage, the frequency of
usage and acceptable runout.

The things that you are up agianst when using such hardware is fact that
these are often open frame motors. The motors are almost universally
series wound DC and the bearings don't last long.

Now the obvious thing is that router motors have been used for years in
systems handling wood or wood like materials. Not knowing you
intentions though makes specfic comments difficult.

Thanks
Dave
