RE: AC Split phase motor????

Hi all, Scot,

  That motor sounds suspiciously like the Sears 1/3hp motor I am using.  I
ground my flats, slapped a 11.5" diameter x 1/2" thick, and it works fine.
Locks into sync so hard it almost clunks.  Give it a whirl, see what
happens!  To the best of my motor knowledge, the split-phase works about the
same as a cap-run motor, only not needing the cap.  It has start windings
that are connected at low RPM, and a weighted slider on the motor shaft
disengages them when it comes up to speed.  That assembly *has* to be in
there, or you'll either burn up the start windings, or it'll take forever to
come up to speed.  It's safe to leave it on the shaft while grinding also,
as mine was a *royal* pain to get off the thing, and there was no need to
remove it I later discovered.  Don't sweat it if the slider-thingey sounds
complex, it isn't.  A minute of fiddling with it reveals how it works.
										Caio!

Hi All...

I had an unpleasant situation occur last week...  I fried my SRSG. :(   the
hi
volt line was too close to the motor mounting bolt, so guess what went to
the
closest ground ??  ;)   )

Altho i did find another motor to replace it, it is a 1/3 HP 1760rpm 120V
model
from Sears.

heres the question..  What is a split phase motor? and can it be modified
for sync
rpms? (1800)
the design "looks" as if it is the same as my last inductive 1/5 hp motor (
windings and core etc) (( 4 field windings and a "solid" rotor)) I searched
the
archives a bit and saw nothing on Split Phase motors.
