motor start/run windings??

Original poster: "David Knaack by way of Terry Fritz <twftesla-at-uswest-dot-net>" <dknaack-at-rdtech-dot-com>

I have salvaged the 1/4hp motor out of a clothing
drier, hopefully for use in rotary spark gap.  It
appears to be a synchronous motor.

It has three input wires, black, yellow and red.
I assumed that black was ground, and attached it
to my variac.  I then flipped a coin and attached
a lead to one of the other leads.  Flip the power
switch and FFFFTTT, the magic smoke all squirted
out of the small-gauge lead.  So I put a new lead
on the other input, and the motor spins up, and
a centripetal switch of some sort on the shaft
clicks.  The motor then seems to run at a constant

The problem is that the motor windings get warm
to the touch in less than 30 seconds.  I don't
know if I've got things connected correctly or
not.  I was thinking maybe I'm powering the start
winding or something, but the diagram on the
schematic shows the start and run windings connected
to an internal switch, which I think is the one I
see change positions when it gets up to speed, so
I kind of thought it would handle switching start
and run windings itself.

Anyway, any suggestions would be appreciated, I can
provide pictures of the motor and the schematic that
came out of the dryer if it would help.
