Re: synchronous motor



Original poster: Ed Phillips <evp@xxxxxxxxxxx>


My SRSG also uses a synchronous 3600RPM motor from an Teletype ASR33 TTY
machine, but the wire colors and connectivity are different than yours,
as mine share a common terminal between the start & run windings.  It
uses an 88-108 (!) uF start cap, and a special starting relay to
energize the start winding/cap as the motor accelerates and draws more
current."

Was that the original starting capacitor? I've never seen a TTY motor using an electrolytic capacitor or one anywhere near that large.
