Re: [CAD_CAM_EDM_DRO] hi-freq motors[perske etc]

Hi, well there are a few mfg in the USA however they get the allmighty buck
and when you find one used,they want to rebuild it for you but when you say
geeze, give me the spec's and what v-freq drive should i use and which pipe
is oil mist, air, and a breakdown of parts available for the spindle. THEN
you might as well ask the Pentagon- its like top secret. someone must make
the motors for Bryant chuck and grinder in VT because the gal i knew at the
motor shop rewound a bunch of them. Advanced control makes them for their
"top secret" printed circuit drilling machines. I know Westwind in the UK
makes a whole bunch of spindle motor/driller/grinder to rpms in the 300
thousand range and in many different hp. ratings. I will keep looking from
this side. cul brian f.

A VERY good question, and one for which an answer is needed! I built a
machine for export to England just-over 15 years back, and used a 3½ hp
Perske 400 Hz router-motor, and it was SUPER-fine (and noisy due to
non-aerodynamic fan-hood on motor) and very, very expensive. But it "did
the
job well". Had to specify English 3-phase voltage for motor/generator (415
VAC/50 Hz in UK), and that confused the Germans, since they expected 240 or
208 VAC/60 Hz, but "we made it, ok")

I sometimes have uses for sub-hp routers for small special CNC WW machines,
but the only such available here are Japanese laminate-trimmers! As
"brush-motors", these outlast U.S.-made several times, over, but still, HF
3-ph. would be nice! TEFC type motors, instead of open, noisy, sparking,
"brush-motors" (fire-hazard!)

Let's see MORE on this topic!!! Jan Rowland
