Phase adjustment on Teletype motor?
Original poster: "John Richardson" <jprich-at-up-dot-net>
Hello,
Has anyone used the old 1/20 hp Teletype motors, the ones with a start
capacitor mounted on the bottom of the motor frame, with John F's phase
controller? I read in the archives that some of these motors didn't
require a capacitor in the phase circuit, just a variac. How true is
this? If anyone has built this circuit with this particular motor, please
let me know what value, if any, you are running. I did order some 370 volt
run caps, both 65 and 25uF, so hopefully I can mix and match and get a
working value. I have been running just the NST across the rotary gap, and
playing with the rotary variac trying to get the electrodes to fire, but no
luck yet. Seems to me that I should be able to adjust the phase of the
SRSG to get the rotary to fire with just the NST, to let me know that my
phase is changing. Info appreciated.
Thanks,
John Richardson
