So, improvements... Is a servo motor torque really linear from zero to rated speed?? I.e. will a 1.5kw AC servo really give me 1.5kw or 2Hp at 100rpm AND at 3000rpm or have i read it wrong??


Would I therefore be better off just fitting a 1.8kw AC servo motor for the drive and connecting at 1:1 ratio??


If it was correct then I would have full power from 1 to 3000rpm at the spindle - sounds ideal.


Would this play well with my upcoming CSMIO/A conversion - would Mach3 give speed control and correct rpm readout??
