Can someone please precisely define a synchro rotary?  I made my rotary out of
a skillsaw blade cut into an 8 pointed star, spinning at about 5400 rpm,
with 8
terminals. (pulley powered). this gives me about 720 pulses a sec.  i will
have
to slow it down to about 400 pulses /sec.  now, what makes a synchro rotary a
synchro rotary?  I have 15 kva pig and .161 mfd maxwell cap.  what formula
would you use to find the optimum pulse rate?
