stepper

["Metlicka Marc" <mystuffs-at-orwell-dot-net> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

now wait a minute, am i doing this math right?
the stepper driver has a max of 1500 pps-at-2.5amps
the motor gives 7.5 deg. per pulse.
that's 12 pulses for 90 deg.      48 pulses for 360 deg. right so far?
31.25 revolutions per second, times 60= 1875rpm.
now i'm really confused cause this aint a bad rpm at 2.5 amp.
1800rpm * 4 electrodes = 7200 / 60(sec.) = 120 bps  give or take from
the 75 extra rpm.
now i got a headack.....regards......marc
